problems in protecting large-dimension power systems, power swing and its effect on distance have caused a lot of damages to energy transfer systems in many parts of the world. Therefore, power swing has gained attentions of many researchers, which has led to invention of different methods for power swing detection. Power swing detection algorithm is highly important in distance relay, but protection relays should have general requirements such as correct fault detection, response rate, and minimization of disturbances in a power system. To ensure meeting the requirements, protection relays need different tests during development, setup, maintenance, configuration, and troubleshooting steps. This paper covers power swing scheme of the modern numerical relay protection, 7sa522 to address the effect of the different fault types on the function of the power swing blocking. In this study, it was shown that the different fault types during power swing cause different time for unblocking distance relay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=power%20swing" title="power swing">power swing</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20relay" title=" distance relay"> distance relay</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system%20protection" title=" power system protection"> power system protection</a>, <a href="https://publications.waset.org/abstracts/search?q=relay%20test" title=" relay test"> relay test</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20in%20power%20system" title=" transient in power system"> transient in power system</a> </p> <a href="https://publications.waset.org/abstracts/82234/realistic-testing-procedure-of-power-swing-blocking-function-in-distance-relay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82234.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23237</span> Automatic Approach for Estimating the Protection Elements of Electric Power Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Mohammad%20Salem%20Al-Suod">Mahmoud Mohammad Salem Al-Suod</a>, <a href="https://publications.waset.org/abstracts/search?q=Ushkarenko%20O.%20Alexander"> Ushkarenko O.

In this paper, the possibility of wireless communication for protection is studied to exchange the information between the relays. The negative sequence and positive sequence directional elements are used to determine the direction of fault current.

Protection system consists of many subsystems like relays, circuit breakers, instrument transformers, auxiliary DC system, auxiliary relays etc. Although the fundamental protective and relay operating concepts are similar throughout the world, there are very significant differences in their implementation. These differences arise through different traditions, operating philosophies, experiences and national standards. Protection system mis-operation due to problem in one or more of its subsystem or inadequate knowledge of numerical relay settings and configuration are very common throughout the world. Protection system mis-operation leads to unstable and unreliable grid operation. In this paper we will discuss about the fundamental concepts of protective relaying and the reasons for protection system mis-operation due to one or more of its subsystems. Many real-world case studies of protection system mis-operation from Indian power sector are discussed in detail in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auxiliary%20trip%20relays" title="auxiliary trip relays">auxiliary trip relays</a>, <a href="https://publications.waset.org/abstracts/search?q=bus%20zone" title=" bus zone"> bus zone</a>, <a href="https://publications.waset.org/abstracts/search?q=check%20zone" title=" check zone"> check zone</a>, <a href="https://publications.waset.org/abstracts/search?q=CT%20saturation" title=" CT saturation"> CT saturation</a>, <a href="https://publications.waset.org/abstracts/search?q=dead%20zone%20protection" title=" dead zone protection"> dead zone protection</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%20ground%20faults" title=" DC ground faults"> DC ground faults</a>, <a href="https://publications.waset.org/abstracts/search?q=DMT" title=" DMT"> DMT</a>, <a href="https://publications.waset.org/abstracts/search?q=DR" title=" DR"> DR</a>, <a href="https://publications.waset.org/abstracts/search?q=end%20fault%20protection" title=" end fault protection"> end fault protection</a>, <a href="https://publications.waset.org/abstracts/search?q=instrument%20transformer" title=" instrument transformer"> instrument transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=SOTF" title=" SOTF"> SOTF</a>, <a href="https://publications.waset.org/abstracts/search?q=STUB" title=" STUB"> STUB</a> </p> <a href="https://publications.waset.org/abstracts/171178/protection-system-mis-operations-fundamental-concepts-and-learning-from-indian-power-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171178.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23234</span> Impact of Very Small Power Producers (VSPP) on Control and Protection System in Distribution Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noppatee%20Sabpayakom">Noppatee Sabpayakom</a>, <a href="https://publications.waset.org/abstracts/search?q=Somporn%20Sirisumrannukul"> Somporn Sirisumrannukul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to incentive policies to promote renewable energy and energy efficiency, high penetration levels of very small power producers (VSPP) located in distribution networks have imposed technical barriers and established new requirements for protection and control of the networks. Although VSPPs have economic and environmental benefit, they may introduce negative effects and cause several challenges on the issue of protection and control system. This paper presents comprehensive studies of possible impacts on control and protection systems based on real distribution systems located in a metropolitan area. A number of scenarios were examined primarily focusing on state of islanding, and un-disconnected VSPP during faults. It is shown that without proper measures to address the issues, the system would be unable to maintain its integrity of electricity power supply for disturbance incidents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control%20and%20protection%20systems" title="control and protection systems">control and protection systems</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20generation" title=" distributed generation"> distributed generation</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=very%20small%20power%20producers" title=" very small power producers"> very small power producers</a> </p> <a href="https://publications.waset.org/abstracts/33565/impact-of-very-small-power-producers-vspp-on-control-and-protection-system-in-distribution-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33565.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">477</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23233</span> A Novel Microcontroller Based Islanding Protection of Distributed Generation Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeid%20Jalilzadeh">Saeid Jalilzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Pakdel"> Majid Pakdel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The customer demand for better power quality and higher reliability has forced the power industry to use distributed generations (DGs) such as wind power and photo voltaic arrays. Islanding is a phenomenon occurs when a power grid becomes electrically isolated from the power system and the distribution system is energized by distributed generators. It is necessary to disconnect all distributed generators immediately after islanding occurrence. Therefore a DG system should have the capability to detect islanding phenomena. In this paper, a novel micro controller based relay for anti-islanding protection of a typical DG system is proposed.

The system uses artificial intelligence as the control terminal, the power generation device executive end uses the Linux system, and Exynos4412 is the CPU. The power generating device collects the sun image information through Sony CCD. After several power generating devices feedback the data to the CPU for processing, several CPUs send the data to the artificial intelligence control terminal through the Internet. The control terminal integrates the executive terminal information, time information, and environmental information to decide whether to generate electricity normally and then whether to convert the converted electrical energy into the grid or store it in the battery pack. When the power generation environment is abnormal, the control terminal authorizes the protection strategy, the power generation device executive terminal stops power generation and enters a self-protection posture, and at the same time, the control terminal synchronizes the data with the cloud. At the same time, the system is more intelligent, more adaptive, and longer life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photo-voltaic%20power%20generation" title="photo-voltaic power generation">photo-voltaic power generation</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20pursuit%20of%20light" title=" the pursuit of light"> the pursuit of light</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title=" internet of things"> internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20array" title=" photovoltaic array"> photovoltaic array</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20management" title=" power management "> power management </a> </p> <a href="https://publications.waset.org/abstracts/126383/design-of-a-photovoltaic-power-generation-system-based-on-artificial-intelligence-and-internet-of-things" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126383.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23231</span> Negative Sequence-Based Protection Techniques for Microgrid Connected Power Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isabelle%20Snyder">Isabelle Snyder</a>, <a href="https://publications.waset.org/abstracts/search?q=Travis%20Smith"> Travis Smith</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microgrid protection presents challenges to conventional protection techniques due to the low-induced fault current. Protection relays present in microgrid applications require a combination of settings groups to adjust based on the architecture of the microgrid in islanded and grid-connected modes. In a radial system where the microgrid is at the other end of the feeder, directional elements can be used to identify the direction of the fault current and switch settings groups accordingly (grid-connected or microgrid-connected). However, with multiple microgrid connections, this concept becomes more challenging, and the direction of the current alone is not sufficient to identify the source of the fault current contribution. ORNL has previously developed adaptive relaying schemes through other DOE-funded research projects that will be evaluated and used as a baseline for this research. The four protection techniques in this study are labeled as follows: (1) Adaptive Current only Protection System (ACPS), Intentional (2) Unbalanced Control for Protection Control (IUCPC), (3) Adaptive Protection System with Communication Controller (APSCC) (4) Adaptive Model-Driven Protective Relay (AMDPR). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20relaying" title="adaptive relaying">adaptive relaying</a>, <a href="https://publications.waset.org/abstracts/search?q=microgrid%20protection" title=" microgrid protection"> microgrid protection</a>, <a href="https://publications.waset.org/abstracts/search?q=sequence%20components" title=" sequence components"> sequence components</a>, <a href="https://publications.waset.org/abstracts/search?q=islanding%20detection" title=" islanding detection"> islanding detection</a> </p> <a href="https://publications.waset.org/abstracts/171820/negative-sequence-based-protection-techniques-for-microgrid-connected-power-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171820.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">96</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23230</span> Protection of Transformers Against Surge Voltage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anil%20S.%20Khopkar">Anil S.

Surge voltages cause significant failure of power system equipment if adequate protection is not provided. A Surge Arrester is a device connected to a power system to protect the equipment against surge voltages. To protect the transformers against surge voltages, metal oxide surge arresters (MOSA) are connected across each terminal. Basic Insulation Level (BIL) has been defined in national and international standards of transformers based on their voltage rating. While designing transformer insulation, the BIL of the transformer, Surge arrester ratings and its operating voltage have to be considered. However, the performance of transformer insulation largely depends on the ratings of the surge arrester connected, the location of the surge arrester, the margin considered in the insulation design, the quantity of surge voltage strike, etc. This paper demonstrates the role of Surge arresters in the protection of transformers against over-voltage, transformer insulation design, optimum location of surge arresters and their connection lead length, Insulation coordination for transformer, protection margin in BIL and methods of protection of transformers against surge voltages, in detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surge%20voltage" title="surge voltage">surge voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=surge%20arresters" title=" surge arresters"> surge arresters</a>, <a href="https://publications.waset.org/abstracts/search?q=insulation%20coordination" title=" insulation coordination"> insulation coordination</a>, <a href="https://publications.waset.org/abstracts/search?q=protection%20margin" title=" protection margin"> protection margin</a> </p> <a href="https://publications.waset.org/abstracts/183790/protection-of-transformers-against-surge-voltage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183790.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23229</span> Distance Protection Performance Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelsalam%20Omar">Abdelsalam Omar </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents simulation-based case study that indicate the need for accurate dynamic modeling of distance protection relay.

The overcurrent protection scheme for the traditional radial type distribution system will no longer meet the needs of microgrid protection. Integrating the intelligent electronic device (IED) and a supervisory control and data acquisition (SCADA) with IEC 61850 communication protocol, the paper proposes a microgrid protection management system (MPMS) to protect power system from the fault. In the proposed method, the MPMS performs logic programming of each IED to coordinate their tripping sequence. The GOOSE message defined in IEC 61850 is used as the transmission information medium among IEDs. Moreover, to cope with the difference in fault current of microgrid between grid-connected mode and islanded mode, the proposed MPMS applies the group setting feature of IED to protect system and robust adaptability. Once the microgrid topology varies, the MPMS will recalculate the fault current and update the group setting of IED. Provided there is a fault, IEDs will isolate the fault at once. Finally, the Matlab/Simulink and Elipse Power Studio software are used to simulate and demonstrate the feasibility of the proposed method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IEC%2061850" title="IEC 61850">IEC 61850</a>, <a href="https://publications.waset.org/abstracts/search?q=IED" title=" IED"> IED</a>, <a href="https://publications.waset.org/abstracts/search?q=group%20Setting" title=" group Setting"> group Setting</a>, <a href="https://publications.waset.org/abstracts/search?q=microgrid" title=" microgrid"> microgrid</a> </p> <a href="https://publications.waset.org/abstracts/37040/a-group-setting-of-ied-in-microgrid-protection-management-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37040.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">461</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23227</span> Modeling of Power Network by ATP-Draw for Lightning Stroke Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Morales">John Morales</a>, <a href="https://publications.waset.org/abstracts/search?q=Armando%20Guzman"> Armando Guzman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Protection relay algorithms play a crucial role in Electric Power System stability, where, it is clear that lightning strokes produce the mayor percentage of faults and outages of Transmission Lines (TLs) and Distribution Feeders (DFs). In this context, it is imperative to develop novel protection relay algorithms. However, in order to get this aim, Electric Power Systems (EPS) network have to be simulated as real as possible, especially the lightning phenomena, and EPS elements that affect their behavior like direct and indirect lightning, insulator string, overhead line, soil ionization and other. However, researchers have proposed new protection relay algorithms considering common faults, which are not produced by lightning strokes, omitting these imperative phenomena for the transmission line protection relays behavior. Based on the above said, this paper presents the possibilities of using the Alternative Transient Program ATP-Draw for the modeling and simulation of some models to make lightning stroke studies, especially for protection relays, which are developed through Transient Analysis of Control Systems (TACS) and MODELS language corresponding to the ATP-Draw. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=back-flashover" title="back-flashover">back-flashover</a>, <a href="https://publications.waset.org/abstracts/search?q=faults" title=" faults"> faults</a>, <a href="https://publications.waset.org/abstracts/search?q=flashover" title=" flashover"> flashover</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20stroke" title=" lightning stroke"> lightning stroke</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling%20of%20lightning" title=" modeling of lightning"> modeling of lightning</a>, <a href="https://publications.waset.org/abstracts/search?q=outages" title=" outages"> outages</a>, <a href="https://publications.waset.org/abstracts/search?q=protection%20relays" title=" protection relays"> protection relays</a> </p> <a href="https://publications.waset.org/abstracts/46948/modeling-of-power-network-by-atp-draw-for-lightning-stroke-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46948.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">316</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23226</span> Techno-Economic Analysis of Solar Energy for Cathodic Protection of Oil and Gas Buried Pipelines in Southwestern of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Goodarzi">M.

These networks generally have a simple protection system usually implemented using fuses, re-closers, and over-current relays. Recently, great attention has been paid to applying Distributed energy resources (DERs) throughout electric distribution systems. Presence of such generation in a network leads to losing coordination of protection devices. Therefore, it is desired to develop an algorithm which is capable of protecting distribution systems that include DER. On the other hand smart grid brings opportunities to the power system. Fast advancement in communication and measurement techniques accelerates the development of multi agent system (MAS). So in this paper, a new approach for the protection of distribution networks in the presence of DERs is presented base on MAS. The proposed scheme has been implemented on a sample 27-bus distribution network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distributed%20energy%20resource" title="distributed energy resource">distributed energy resource</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution%20network" title=" distribution network"> distribution network</a>, <a href="https://publications.waset.org/abstracts/search?q=protection" title=" protection"> protection</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20grid" title=" smart grid"> smart grid</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20agent%20system" title=" multi agent system"> multi agent system</a> </p> <a href="https://publications.waset.org/abstracts/33470/a-multi-agent-based-protection-scheme-for-smart-distribution-network-in-presence-of-distributed-energy-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33470.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">608</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23224</span> Application of Support Vector Machines in Fault Detection and Diagnosis of Power Transmission Lines </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20A.%20Farhat">I.

It has a wide application prospect in superconducting energy-removal, generator de-excitation, overvoltage protection of electrical & electronics equipment. At present, the research for the application of ZnO voltage dependent resistor stop, it uses just in the field of its nonlinear voltage current characteristic and overvoltage protection areas. There is no further study over the over-voltage breakdown characteristics, such as the combustion phenomena and the measure of the voltage/current when it breakdown, and the affect to its surrounding equipment. It is also a blind spot in its application. So, when we do the feature test of ZnO voltage dependent resistor, we need to design a reasonable test power supply, making the terminal voltage keep for sine wave, simulating the real use of PF voltage in power supply conditions. We put forward the solutions of using inverter to generate a controllable power. The paper mainly focuses on the breakdown characteristic test power supply of nonlinear ZnO voltage dependent resistor. According to the current mature switching power supply technology, we proposed power control system using the inverter as the core. The power mainly realize the sin-voltage output on the condition of three-phase PF-AC input, and 3 control modes (RMS, Peak, Average) of the current output. We choose TMS320F2812M as the control part of the hardware platform. It is used to convert the power from three-phase to a controlled single-phase sin-voltage through a rectifier, filter, and inverter. Design controller produce SPWM, to get the controlled voltage source via appropriate multi-loop control strategy, while execute data acquisition and display, system protection, start logic control, etc. The TMS320F2812M is able to complete the multi-loop control quickly and can be a good completion of the inverter output control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ZnO" title="ZnO">ZnO</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-loop%20control" title=" multi-loop control"> multi-loop control</a>, <a href="https://publications.waset.org/abstracts/search?q=SPWM" title=" SPWM"> SPWM</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20load" title=" non-linear load"> non-linear load</a> </p> <a href="https://publications.waset.org/abstracts/1333/control-algorithm-design-of-single-phase-inverter-for-zno-breakdown-characteristics-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1333.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">325</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23222</span> The Importance of Fire Safety in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Shakra">Omar Shakra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper contains a huge number of benefits that we can use it in several places and times in fire safety protection in the Middle East especially in Egypt .

However when the power system experiences an abnormal situation leading to huge current flow, then this huge current is proportionally injected to the protection and metering circuit. Since the protection and metering equipment’s are designed to withstand only certain amount of current with respect to time, these high currents pose a risk to man and equipment. Therefore during such instances, the CT saturation characteristics have a huge influence on the safety of both man and equipment and also on the reliability of the protection and metering system. This paper shows the effect of burden on the Accuracy Limiting factor/ Instrument security factor of current transformers and also the change in saturation characteristics of the CT’s. The response of the CT to varying levels of overcurrent at different connected burden will be captured using the data acquisition software LabVIEW. Analysis is done on the real time data gathered using LabVIEW. Variation of current transformer saturation characteristics with changes in burden will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accuracy%20limiting%20factor" title="accuracy limiting factor">accuracy limiting factor</a>, <a href="https://publications.waset.org/abstracts/search?q=burden" title=" burden"> burden</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20transformer" title=" current transformer"> current transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=instrument%20security%20factor" title=" instrument security factor"> instrument security factor</a>, <a href="https://publications.waset.org/abstracts/search?q=saturation%20characteristics" title=" saturation characteristics"> saturation characteristics</a> </p> <a href="https://publications.waset.org/abstracts/37462/analyzing-current-transformers-saturation-characteristics-for-different-connected-burden-using-labview-data-acquisition-tool" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37462.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">415</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23220</span> Transmission Line Protection Challenges under High Penetration of Renewable Energy Sources and Proposed Solutions: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Melake%20Kuflom">Melake Kuflom</a> </p> <p class="card-text"><strong>Abstract:</strong></p> European power networks involve the use of multiple overhead transmission lines to construct a highly duplicated system that delivers reliable and stable electrical energy to the distribution level. The transmission line protection applied in the existing GB transmission network are normally independent unit differential and time stepped distance protection schemes, referred to as main-1 & main-2 respectively, with overcurrent protection as a backup. The increasing penetration of renewable energy sources, commonly referred as “weak sources,” into the power network resulted in the decline of fault level. Traditionally, the fault level of the GB transmission network has been strong; hence the fault current contribution is more than sufficient to ensure the correct operation of the protection schemes. However, numerous conventional coal and nuclear generators have been or about to shut down due to the societal requirement for CO2 emission reduction, and this has resulted in a reduction in the fault level on some transmission lines, and therefore an adaptive transmission line protection is required. Generally, greater utilization of renewable energy sources generated from wind or direct solar energy results in a reduction of CO2 carbon emission and can increase the system security and reliability but reduces the fault level, which has an adverse effect on protection. Consequently, the effectiveness of conventional protection schemes under low fault levels needs to be reviewed, particularly for future GB transmission network operating scenarios.

Presently, the applications of Phasor Measurement Unit (PMU) are widely found in real time operation, monitoring, controlling and analysis of power system network as it eliminates the various limitations of Supervisory Control and Data Acquisition System (SCADA) conventionally used in power system. The use of PMU data is very rapidly increasing its importance for online and offline analysis. Wide Area Measurement System (WAMS) is developed as new technology by use of multiple PMUs in power system. The present paper proposes a model of MATLAB based PMU using Discrete Fourier Transform (DFT) algorithm and evaluation of its operation under different contingencies.

CPS are particularly characterized by their networking system components. This means they are able to adapt to the needs of their users and its environment. With this ability, CPS have new, specific requirements on the protection against anti-counterfeiting, know-how loss and manipulation. They increase the requirements on system protection because piracy attacks can be more diverse, for example because of an increasing number of interfaces or through the networking abilities. The new requirements were identified and in a next step matched with existing protective measures. Due to the found gap the development of new protection measures has to be forced to close this gap.

In order to mitigate this problem, a meticulous planning of the power substation protection system is of vital importance. A critical part of this is the distribution of shielding wires through the substation, which creates a 3D imaginary protection mesh similar to a circus tarpaulin. Equipment enclosed in the volume defined by that 3D mesh is considered protected against lightning strikes. The use of traditional methods of longitudinal cutting analysis based on 2D CAD tools makes the process laborious and the results obtained may not guarantee satisfactory protection of electrical equipment. This work describes the application of a Game Engine to the problem of lightning protection of power substations providing the visualization of the 3D protection mesh, the amount of protected components and the highlight of equipment which remain unprotected. In addition, aspects regarding the implementation and the advantages of approaching the problem using Unreal® Engine 4 are described. In order to validate results, a comparison with traditional 2D methods is applied to the same case study to which the proposed technique has been applied. Finally, a comparative study involving different levels of protection using the technique developed in this work is presented, showing that modern game engines can be a powerful accessory for simulations in several areas of engineering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=game%20engine" title="game engine">game engine</a>, <a href="https://publications.waset.org/abstracts/search?q=rolling%20spheres%20method" title=" rolling spheres method"> rolling spheres method</a>, <a href="https://publications.waset.org/abstracts/search?q=substation%20protection" title=" substation protection"> substation protection</a>, <a href="https://publications.waset.org/abstracts/search?q=UE4" title=" UE4"> UE4</a>, <a href="https://publications.waset.org/abstracts/search?q=Unreal%20Engine%204" title=" Unreal Engine 4"> Unreal Engine 4</a> </p> <a href="https://publications.waset.org/abstracts/80764/using-game-engines-in-lightning-shielding-the-application-of-the-rolling-spheres-method-on-virtual-as-built-power-substations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80764.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">527</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23213</span> Radiation Protection Study for the Assessment of Mixed Fields Ionizing Radiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avram%20Irina">Avram Irina</a>, <a href="https://publications.waset.org/abstracts/search?q=Coiciu%20Eugenia-Mihaela"> Coiciu Eugenia-Mihaela</a>, <a href="https://publications.waset.org/abstracts/search?q=Popovici%20Mara-Georgiana"> Popovici Mara-Georgiana</a>, <a href="https://publications.waset.org/abstracts/search?q=Mitu%20Iani%20Octavian"> Mitu Iani Octavian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> ELI-NP stands as a cutting-edge facility globally, hosting unique radiological setups.

Protection relays present in microgrid applications require a combination of settings groups to adjust based on the architecture of the microgrid in islanded and grid-connected mode. In a radial system where the microgrid is at the other end of the feeder, directional elements can be used to identify the direction of the fault current and switch settings groups accordingly (grid connected or microgrid connected). However, with multiple microgrid connections, this concept becomes more challenging, and the direction of the current alone is not sufficient to identify the source of the fault current contribution. ORNL has previously developed adaptive relaying schemes through other DOE-funded research projects that will be evaluated and used as a baseline for this research. The four protection techniques in this study are the following: (1) Adaptive Current only Protection System (ACPS), Intentional (2) Unbalanced Control for Protection Control (IUCPC), (3) Adaptive Protection System with Communication Controller (APSCC) (4) Adaptive Model-Driven Protective Relay (AMDPR). The first two methods focus on identifying the islanded mode without communication by monitoring the current sequence component generated by the system (ACPS) or induced with inverter control during islanded mode (IUCPC) to identify the islanding condition without communication at the relay to adjust the settings. These two methods are used as a backup to the APSCC, which relies on a communication network to communicate the islanded configuration to the system components. The fourth method relies on a short circuit model inside the relay that is used in conjunction with communication to adjust the system configuration and computes the fault current and adjusts the settings accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20relaying" title="adaptive relaying">adaptive relaying</a>, <a href="https://publications.waset.org/abstracts/search?q=microgrid%20protection" title=" microgrid protection"> microgrid protection</a>, <a href="https://publications.waset.org/abstracts/search?q=sequence%20components" title=" sequence components"> sequence components</a>, <a href="https://publications.waset.org/abstracts/search?q=islanding%20detection" title=" islanding detection"> islanding detection</a>, <a href="https://publications.waset.org/abstracts/search?q=communication%20controlled%20protection" title=" communication controlled protection"> communication controlled protection</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20short%20circuit%20model" title=" integrated short circuit model"> integrated short circuit model</a> </p> <a href="https://publications.waset.org/abstracts/155921/sequence-component-based-adaptive-protection-for-microgrids-connected-power-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155921.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23211</span> Lightning Protection Design Applied to Sustainable Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sylvain%20Fauveaux">Sylvain Fauveaux</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Nowicki"> T.

In the study results, it is seen that MGs affect system voltage stability positively by increasing system voltage instability limit value for buses of a power system in which MG are placed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eigenvalue%20analysis" title="eigenvalue analysis">eigenvalue analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=microgrid" title=" microgrid"> microgrid</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20analysis" title=" modal analysis"> modal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20stability" title=" voltage stability"> voltage stability</a> </p> <a href="https://publications.waset.org/abstracts/76026/modal-analysis-of-power-system-with-a-microgrid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76026.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23209</span> Enhance Power Quality by HVDC System, Comparison Technique between HVDC and HVAC Transmission Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Smko%20Zangana">Smko Zangana</a>, <a href="https://publications.waset.org/abstracts/search?q=Ergun%20Ercelebi"> Ergun Ercelebi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The alternating current is the main power in all industries and other aspects especially for the short and mid distances, but as far as long a distance which exceeds 500 KMs, using the alternating current technically will face many difficulties and more costs because it's difficult to control the current and also other restrictions. Therefore, recently those reasons led to building transmission lines HVDC to transmit power for long distances. This document presents technical comparison and assessments for power transmission system among distances either ways and studying the stability of the system regarding the proportion of losses in the actual power sent and received between both sides in different systems and also categorizing filters used in the HVDC system and its impact and effect on reducing Harmonic in the power transmission. MATLAB /Simulink simulation software is used to simulate both HVAC & HVDC power transmission system topologies. <p class="card-text"><strong>Keywords:</strong> <a
