The multi-line and multi-type Flexible alternating current transmission system (FACTS) controllers are playing a vital role to regulate power flow through the transmission line. Unified power flow controller and interline power flow controller can be utilized to control reactive power flow through the transmission line. In a restructured power system, the demand of such controller is being popular due to their inherent capability. The transmission pricing by using reactive power cost allocation through modified matrix methodology has been proposed. The FACTS technologies have quite costly assembly, so it is very useful to apportion the expenses throughout the restructured electricity industry. Therefore, in this work, after embedding the FACTS devices into load flow, the impact on the costs allocated to users in fraction to the transmission framework utilization has been analyzed. From the obtained results, it is clear that the total cost recovery is enhanced towards the Reactive Power flow through the different transmission line for 5 bus test system. The fair pricing policy towards reactive power can be achieved by the proposed method incorporating FACTS controller towards cost recovery of the transmission network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interline%20power%20flow%20controller" title="interline power flow controller">interline power flow controller</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20pricing" title=" transmission pricing"> transmission pricing</a>, <a href="https://publications.waset.org/abstracts/search?q=unified%20power%20flow%20controller" title=" unified power flow controller"> unified power flow controller</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20allocation" title=" cost allocation"> cost allocation</a> </p> <a href="https://publications.waset.org/abstracts/109581/influence-of-power-flow-controller-on-energy-transaction-charges-in-restructured-power-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109581.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">148</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">10114</span> The Impact of System Cascading Collapse and Transmission Line Outages to the Transfer Capability Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nur%20Ashida%20Salim">Nur Ashida Salim</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Murtadha%20Othman"> Muhammad Murtadha Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Musirin"> Ismail Musirin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Salleh%20Serwan"> Mohd Salleh Serwan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Uncertainty of system operating conditions is one of the causative reasons which may render to the instability of a transmission system. This will encumber the performance of transmission system to efficiently transmit the electrical power between areas. For that reason, accurate assessment of Transmission Reliability Margin (TRM) is essential in order to ensure effective power transfer between areas during the occurrence of system uncertainties. The power transfer is also called as the Available Transfer Capability (ATC) in which it is the information required by the utilities and marketers to instigate selling and buying the electric energy. This paper proposes a computationally effective approach to estimate TRM and ATC by considering the uncertainties of system cascading collapse and transmission line outages which is identified as the main reasons in power system instability. In accordance to the results that have been obtained, the proposed method is essential for the transmission providers which could help the power marketers and planning sectors in the operation and reserving transmission services based on the ATC calculated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=system%20cascading%20collapse" title="system cascading collapse">system cascading collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20line%20outages" title=" transmission line outages"> transmission line outages</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20reliability%20margin" title=" transmission reliability margin"> transmission reliability margin</a>, <a href="https://publications.waset.org/abstracts/search?q=available%20transfer%20capability" title=" available transfer capability"> available transfer capability</a> </p> <a href="https://publications.waset.org/abstracts/4349/the-impact-of-system-cascading-collapse-and-transmission-line-outages-to-the-transfer-capability-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4349.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">426</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">10113</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.

Key performance indicators (KPIs) are often used as measure of degree of performance. This paper gives a novel method to determine the transmission efficiency by evaluating the ratio of real power losses incurred from a specified transfer direction. Available Transmission Transfer Efficiency (ATTE) expresses the percentage of real power received resulting from inter-area available power transfer. The Tie line (Rated system path) performance is seen to differ from system wide (Network response) performance and ATTE values obtained are transfer direction specific. The required sending end quantities with specified receiving end ATC and the receiving end power circle diagram are obtained for the tie line analysis. The amount of real power loss load relative to the available transfer capability gives a measure of the transmission grid efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance" title="performance">performance</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20system" title=" transmission system"> transmission system</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20power%20%0D%0Aefficiency" title=" real power efficiency"> real power efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=available%20transfer%20capability" title=" available transfer capability"> available transfer capability</a> </p> <a href="https://publications.waset.org/abstracts/24119/available-transmission-transfer-efficiency-atte-as-an-index-measurement-for-power-transmission-grid-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24119.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">649</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">10109</span> Study of Ground Level Electric Field under 800 kV HVDC Unipolar Laboratory level Transmission line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Urukundu">K.

This is because the transfer of bulk power through HVDC, from generating stations to load centers over long distances is more economical. However, these HVDC transmission lines create environmental and interference effects under the right of way of the line due to the ionization of the surrounding atmosphere in the vicinity of HVDC lines. The measurement of ground-level electric field and ionic current density is essential for the evaluation of human effects due to electromagnetic interference of the HVDC transmission line. In this paper, experimental laboratory results of the ground-level electric field under the miniature model of 800 kV monopole HVDC line of length 8 meters are presented in lateral configuration with different heights of the conductor from the ground plane. The results are compared with the simulated test results obtained through Finite Element based software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bundle" title="bundle">bundle</a>, <a href="https://publications.waset.org/abstracts/search?q=conductor" title=" conductor"> conductor</a>, <a href="https://publications.waset.org/abstracts/search?q=hexagonal" title=" hexagonal"> hexagonal</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20line" title=" transmission line"> transmission line</a>, <a href="https://publications.waset.org/abstracts/search?q=ground-level%20electric%20field" title=" ground-level electric field"> ground-level electric field</a> </p> <a href="https://publications.waset.org/abstracts/145989/study-of-ground-level-electric-field-under-800-kv-hvdc-unipolar-laboratory-level-transmission-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145989.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">221</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">10108</span> Carrier Communication through Power Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pavuluri%20Gopikrishna">Pavuluri Gopikrishna</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20Neelima"> B.

The main objective of this suggested work is to transmit our message signal after frequency modulation by the help of FM modulator IC LM565 which gives output proportional to the input voltage of the input message signal. And this audio power is received from the power line by the help of isolation circuit and demodulated from IC LM565 which uses the concept of the PLL and produces FM demodulated signal to the listener. Message signal will be transmitted over the carrier signal that will be generated from the FM modulator IC LM565. Using this message signal will not damage because of no direct contact of message signal from the power line, but noise can disturb our information. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amplification" title="amplification">amplification</a>, <a href="https://publications.waset.org/abstracts/search?q=fm%20demodulator%20ic%20565" title=" fm demodulator ic 565"> fm demodulator ic 565</a>, <a href="https://publications.waset.org/abstracts/search?q=fm%20modulator%20ic%20565" title=" fm modulator ic 565"> fm modulator ic 565</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20locked%20loop" title=" phase locked loop"> phase locked loop</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20isolation" title=" power isolation"> power isolation</a> </p> <a href="https://publications.waset.org/abstracts/31017/carrier-communication-through-power-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31017.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">552</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">10107</span> Effect of Parameters for Exponential Loads on Voltage Transmission Line with Compensation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benalia%20Nadia">Benalia Nadia</a>, <a href="https://publications.waset.org/abstracts/search?q=Bensiali%20Nadia"> Bensiali Nadia</a>, <a href="https://publications.waset.org/abstracts/search?q=Zerzouri%20Noura"> Zerzouri Noura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an analysis of the effects of parameters np and nq for exponential load on the transmission line voltage profile, transferred power and transmission losses for different shunt compensation size.

The amount of the parcels, which are affected by the negativity of PTL is clearly seen with the aid of generated maps. Some kind of changes are exhibited in the system, which are created by GIS, for instance before urban regeneration PTL was very close to people’s private properties and huge parts of PTL were among the buildings, however; after urban regeneration electricity lines were changed their locations to the underground. According to the results, GIS can be used as a device in planning and managing of PTL in urban regeneration projects and can be used for analyses.

Thangalakshmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is a widespread changeover in the electrical power industry universally from old-style monopolistic outline towards a horizontally distributed competitive structure to come across the demand of rising consumption. When the transmission lines of derestricted system are incapable to oblige the entire service needs, the lines are overloaded or congested. The governor between customer and power producer is nominated as Independent System Operator (ISO) to lessen the congestion without obstructing transmission line restrictions. Among the existing approaches for congestion management, the frequently used approaches are reorganizing the generation and load curbing. There is a boundary for reorganizing the generators, and further loads may not be supplemented with the prevailing resources unless more private power producers are added in the system by considerably raising the cost. Hence, congestion is relaxed by appropriate Flexible AC Transmission Systems (FACTS) devices which boost the existing transfer capacity of transmission lines. The FACTs device, namely, Unified Power Flow Controller (UPFC) is preferred, and the correct placement of UPFC is more vital and should be positioned in the highly congested line. Hence, the weak line is identified by using power flow performance index with the new objective function with proposed hybrid Fish – Bee algorithm. Further, the location of UPFC at appropriate line reduces the branch loading and minimizes the voltage deviation. The power transfer capacity of lines is determined with and without UPFC in the identified congested line of IEEE 30 bus structure and the simulated results are compared with prevailing algorithms. It is observed that the transfer capacity of existing line is increased with the presented algorithm and thus alleviating the congestion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=available%20line%20transfer%20capability" title="available line transfer capability">available line transfer capability</a>, <a href="https://publications.waset.org/abstracts/search?q=congestion%20management" title=" congestion management"> congestion management</a>, <a href="https://publications.waset.org/abstracts/search?q=FACTS%20device" title=" FACTS device"> FACTS device</a>, <a href="https://publications.waset.org/abstracts/search?q=Hybrid%20Fish-Bee%20Algorithm" title=" Hybrid Fish-Bee Algorithm"> Hybrid Fish-Bee Algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=ISO" title=" ISO"> ISO</a>, <a href="https://publications.waset.org/abstracts/search?q=UPFC" title=" UPFC"> UPFC</a> </p> <a href="https://publications.waset.org/abstracts/57011/transmission-line-congestion-management-using-hybrid-fish-bee-algorithm-with-unified-power-flow-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57011.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">383</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">10103</span> Influence of the Line Parameters in Transmission Line Fault Location</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marian%20Dragomir">Marian Dragomir</a>, <a href="https://publications.waset.org/abstracts/search?q=Alin%20Dragomir"> Alin Dragomir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the paper, two fault location algorithms are presented for transmission lines which use the line parameters to estimate the distance to the fault.

Power system restoration is an immensely complex issue and there should be a plan to be executed within the shortest time period. This plan has three main stages of black start, network reconfiguration and load restoration. In the black start stage, operators and experts may face several problems, for instance, the unsuccessful connection of the long high-voltage transmission line connected to the electrical source. In this situation, the generator may be tripped because of the unsuitable setting of its line charging mode or high absorbed reactive power. In order to solve this problem, the line charging process is defined as a nonlinear programming problem, and it is optimized by using GAMS software in this paper. The optimized process is performed on a grid that includes a 250 MW hydroelectric unit and a 400 KV transmission system.

This is due to the complications of a strain power system. With the snowballing of power demand by the consumers and also the restricted amount of power sources, therefore, the system has to perform at its maximum proficiency. Consequently, the noteworthy to discover the maximum ability boundary prior to voltage collapse should be undertaken. A preliminary warning can be perceived to evade the interruption of power system’s capacity. The effectiveness of line voltage stability indices (LVSI) is differentiated in this paper. The main purpose of the indices is used to predict the proximity of voltage instability of the electric power system. On the other hand, the indices are also able to decide the weakest load buses which are close to voltage collapse in the power system. The line stability indices are assessed using the IEEE 14 bus test system to validate its practicability. Results demonstrated that the implemented indices are practically relevant in predicting the manifestation of voltage collapse in the system. Therefore, essential actions can be taken to dodge the incident from arising. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20line" title="critical line">critical line</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20outage" title=" line outage"> line outage</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20voltage%20stability%20indices%20%28LVSI%29" title=" line voltage stability indices (LVSI)"> line voltage stability indices (LVSI)</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20loadability" title=" maximum loadability"> maximum loadability</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20collapse" title=" voltage collapse"> voltage collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20instability" title=" voltage instability"> voltage instability</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20stability%20analysis" title=" voltage stability analysis"> voltage stability analysis</a> </p> <a href="https://publications.waset.org/abstracts/15431/comparative-study-of-line-voltage-stability-indices-for-voltage-collapse-forecasting-in-power-transmission-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15431.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">360</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">10098</span> Mitigation of Cascading Power Outage Caused Power Swing Disturbance Using Real-time DLR Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dejenie%20Birile%20Gemeda">Dejenie Birile Gemeda</a>, <a href="https://publications.waset.org/abstracts/search?q=Wilhelm%20Stork"> Wilhelm Stork</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The power system is one of the most important systems in modern society. The existing power system is approaching the critical operating limits as views of several power system operators. With the increase of load demand, high capacity and long transmission networks are widely used to meet the requirement. With the integration of renewable energies such as wind and solar, the uncertainty, intermittence bring bigger challenges to the operation of power systems. These dynamic uncertainties in the power system lead to power disturbances. The disturbances in a heavily stressed power system cause distance relays to mal-operation or false alarms during post fault power oscillations. This unintended operation of these relays may propagate and trigger cascaded trappings leading to total power system blackout. This is due to relays inability to take an appropriate tripping decision based on ensuing power swing. According to the N-1 criterion, electric power systems are generally designed to withstand a single failure without causing the violation of any operating limit. As a result, some overloaded components such as overhead transmission lines can still work for several hours under overload conditions. However, when a large power swing happens in the power system, the settings of the distance relay of zone 3 may trip the transmission line with a short time delay, and they will be acting so quickly that the system operator has no time to respond and stop the cascading. Misfiring of relays in absence of fault due to power swing may have a significant loss in economic performance, thus a loss in revenue for power companies. This research paper proposes a method to distinguish stable power swing from unstable using dynamic line rating (DLR) in response to power swing or disturbances. As opposed to static line rating (SLR), dynamic line rating support effective mitigation actions against propagating cascading outages in a power grid. Effective utilization of existing transmission lines capacity using machine learning DLR predictions will improve the operating point of distance relay protection, thus reducing unintended power outages due to power swing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blackout" title="blackout">blackout</a>, <a href="https://publications.waset.org/abstracts/search?q=cascading%20outages" title=" cascading outages"> cascading outages</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20line%20rating" title=" dynamic line rating"> dynamic line rating</a>, <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=overhead%20transmission%20lines" title=" overhead transmission lines"> overhead transmission lines</a> </p> <a href="https://publications.waset.org/abstracts/144172/mitigation-of-cascading-power-outage-caused-power-swing-disturbance-using-real-time-dlr-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144172.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">143</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">10097</span> Structural Safety Assessment of Transmission Tower with High-Low Legs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chi-Rung%20Jiang">Chi-Rung Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Chung%20Chen"> Chun-Chung Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheng-Yuan%20Shiao"> Sheng-Yuan Shiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Fang-Yao%20Yeh"> Fang-Yao Yeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transmission lines are essential for power systems which play a significant role in a city for the development of infrastructures. Once a tower on the transmission line is damaged or becomes unstable, small-scale transmission tower damage might cause a large-scale electric power failure, and consequently, the enormous economic losses will occur. This paper assesses the structural safety and considers the impact of earthquakes and winds, presents a preliminary study of transmission tower with high-low legs by building structural analysis models of towers. The result shows that the high-low legs towers do have some structural characteristics need to be considered, such as the length of the difference of high legs and low legs should be restricted and the deployment direction of legs must be carefully planned during the design of transmission towers. The outcome of this study is beneficial to power systems authorities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=power%20transition%20tower" title="power transition tower">power transition tower</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20analysis" title=" structural analysis"> structural analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=high-low%20legs" title=" high-low legs"> high-low legs</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20assessment" title=" safety assessment"> safety assessment</a> </p> <a href="https://publications.waset.org/abstracts/105503/structural-safety-assessment-of-transmission-tower-with-high-low-legs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105503.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">223</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">10096</span> STATCOM’s Contribution to the Improvement of Voltage Plan and Power Flow in an Electrical Transmission Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Adjabi">M.

It requires a robust infrastructure that can last for decades without causing impairment in human life. Due to the so-called global warming, power transmission system has started to experience some challenges which could presumably escalate more in future. These challenges are earthquake resistance, transmission power losses, and high electromagnetic field. In this paper, research efforts aim to address these challenges are discussed. We focus in particular on the research in regenerative electric energy such as: wind, hydropower, biomass and sea-waves based on the energy storage and transmission possibility.

Thus, other devices such as shield wires, insulators, towers, foundations etc. should be designed in a way that the conductors be able to successfully do their task which is appropriate power delivery to the customers. Non-stop increase of energy demand has led to saturated capacity of transmission lines which, in turn, causing line flash to exceed acceptable limits in some points. An approach which may be used to solve this issue is replacement of current conductors with new ones having the capability of withstanding higher heating such that reduced flash would be observed when heating increases. These novel conductors are able to transfer higher currents and operate in higher heating conditions while line flash will remain within standard limits. In this paper, we will attempt to introduce three types of advanced overhead conductors and analyze the replacement of current conductors by new ones technically and economically in transmission lines.

The majority of existing models for surface gradient calculations are based on analytical methods which restrict their application in simulating complex surface geometry. This paper proposes a novel technique which utilizes both analytical and numerical procedure to predict the surface gradient. One of 400 kV transmission line configurations has been selected as an example to compare the results for different methods.

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. The proposed paper will evaluate the transmission line challenges under high penetration of renewable energy sources andprovides alternative viable protection solutions based on the problem observed. The paper will consider the assessment ofrenewable energy sources (RES) based on a fully rated converter technology. The DIgSILENT Power Factory software tool will be used to model the network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fault%20level" title="fault level">fault level</a>, <a href="https://publications.waset.org/abstracts/search?q=protection%20schemes" title=" protection schemes"> protection schemes</a>, <a href="https://publications.waset.org/abstracts/search?q=relay%20settings" title=" relay settings"> relay settings</a>, <a href="https://publications.waset.org/abstracts/search?q=relay%20coordination" title=" relay coordination"> relay coordination</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy%20sources" title=" renewable energy sources"> renewable energy sources</a> </p> <a href="https://publications.waset.org/abstracts/146109/transmission-line-protection-challenges-under-high-penetration-of-renewable-energy-sources-and-proposed-solutions-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146109.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">206</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">10089</span> Power Flow and Modal Analysis of a Power System Including Unified Power Flow Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djilani%20Kobibi%20Youcef%20Islam">Djilani Kobibi Youcef Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadjeri%20Samir"> Hadjeri Samir</a>, <a href="https://publications.waset.org/abstracts/search?q=Djehaf%20Mohamed%20Abdeldjalil"> Djehaf Mohamed Abdeldjalil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Flexible AC Transmission System (FACTS) technology is a new advanced solution that increases the reliability and provides more flexibility, controllability, and stability of a power system.

Minute current can travel though human body without any harm. IBC can remove electrical wires for human area network. IBC can be also a secure communication network system unlike wireless networks which can be accessed by anyone with bad intentions. One of the IBC systems is based on frequency shift keying modulation where individual data are transmitted to the external devices for the purpose of secure access such as digital door lock. It was found that the quality of IBC data transmission was heavily dependent on ground configurations of electronic circuits. Reliable IBC transmissions were not possible when both of the transmitter and receiver used batteries as circuit power source. Transmission was reliable when power supplies were used as power source for both transmitting and receiving sites because the common ground was established through the grounds of instruments such as power supply and oscilloscope. This was due to transmission dipole size and the ground effects of floor and AC power line. If one site used battery as power source and the other site used the AC power as circuit power source, transmission was possible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frequency%20shift%20keying" title="frequency shift keying">frequency shift keying</a>, <a href="https://publications.waset.org/abstracts/search?q=ground" title=" ground"> ground</a>, <a href="https://publications.waset.org/abstracts/search?q=intrabody" title=" intrabody"> intrabody</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a>, <a href="https://publications.waset.org/abstracts/search?q=door%20lock" title=" door lock"> door lock</a> </p> <a href="https://publications.waset.org/abstracts/12052/intrabody-communication-using-different-ground-configurations-in-digital-door-lock" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12052.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">418</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">10087</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.
