It occurs due to the fault in the electrical network or by the starting of a large induction motor and this can be solved by using the custom power devices such as Dynamic Voltage Restorer (DVR). In this paper DVR is proposed to compensate voltage sags on critical loads dynamically. The DVR consists of VSC, injection transformers, passive filters and energy storage (lead acid battery). By injecting an appropriate voltage, the DVR restores a voltage waveform and ensures constant load voltage. The simulation and experimental results of a DVR using MATLAB software shows clearly the performance of the DVR in mitigating voltage sags.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Dynamic%20voltage%20restorer" title="Dynamic voltage restorer">Dynamic voltage restorer</a>, <a href="https://publications.waset.org/search?q=Voltage%20sags" title=" Voltage sags"> Voltage sags</a>, <a href="https://publications.waset.org/search?q=Power%0D%0Aquality" title=" Power quality"> Power quality</a>, <a href="https://publications.waset.org/search?q=Injection%20methods." title=" Injection methods."> Injection methods.</a> </p> <a href="https://publications.waset.org/9999573/modeling-and-simulation-of-dynamic-voltage-restorer-for-mitigation-of-voltage-sags" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9999573/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9999573/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9999573/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9999573/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9999573/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9999573/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9999573/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9999573/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9999573/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9999573/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9999573.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">4286</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">921</span> Artificial Voltage-Controlled Capacitance and Inductance using Voltage-Controlled Transconductance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Mansour%20I.%20Abbadi">Mansour I.

The technique is based on injecting the current of a voltage-controlled current source onto a fixed capacitor or inductor. Then, by controlling the transconductance of the current source by an external bias voltage, a voltage-controlled capacitive or inductive reactance is obtained. The proposed voltage-controlled reactance devices can be designed to work anywhere in the frequency spectrum. Practical circuits for the proposed voltage-controlled reactances are suggested and simulated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=voltage-controlled%20capacitance" title="voltage-controlled capacitance">voltage-controlled capacitance</a>, <a href="https://publications.waset.org/search?q=voltage-controlled%20inductance" title=" voltage-controlled inductance"> voltage-controlled inductance</a>, <a href="https://publications.waset.org/search?q=varactor%20diode" title="varactor diode">varactor diode</a>, <a href="https://publications.waset.org/search?q=variable%20transconductance." title=" variable transconductance."> variable transconductance.</a> </p> <a href="https://publications.waset.org/12213/artificial-voltage-controlled-capacitance-and-inductance-using-voltage-controlled-transconductance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/12213/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/12213/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/12213/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/12213/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/12213/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/12213/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/12213/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/12213/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/12213/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/12213/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/12213.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">4827</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">920</span> Static Voltage Stability Margin Enhancement Using SVC and TCSC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Mohammed%20Amroune">Mohammed Amroune</a>, <a href="https://publications.waset.org/search?q=Hadi%20Sebaa"> Hadi Sebaa</a>, <a href="https://publications.waset.org/search?q=Tarek%20Bouktir"> Tarek Bouktir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Reactive power limit of power system is one of the major causes of voltage instability.

ESD has become a serious problem in the semiconductor process because the semiconductor density has become very high these days. Therefore, much research has been done to prevent ESD. The proposed circuit is a stacked structure of the new unit structure combined by the Zener Triggering (SCR ZTSCR) and the High Holding Voltage SCR (HHVSCR). The simulation results show that the proposed circuit has low trigger voltage and high holding voltage. And the stack technology is applied to adjust the various operating voltage. As the results, the holding voltage is 7.7 V for 2-stack and 10.7 V for 3-stack. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=ESD" title="ESD">ESD</a>, <a href="https://publications.waset.org/search?q=SCR" title=" SCR"> SCR</a>, <a href="https://publications.waset.org/search?q=latch-up" title=" latch-up"> latch-up</a>, <a href="https://publications.waset.org/search?q=power%20clamp" title=" power clamp"> power clamp</a>, <a href="https://publications.waset.org/search?q=holding%20voltage." title=" holding voltage."> holding voltage.</a> </p> <a href="https://publications.waset.org/10008332/a-study-on-esd-protection-circuit-applying-silicon-controlled-rectifier-based-stack-technology-with-high-holding-voltage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10008332/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10008332/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10008332/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10008332/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10008332/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10008332/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10008332/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10008332/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10008332/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10008332/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10008332.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">989</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">916</span> Technique for Voltage Control in Distribution System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=S.%20Thongkeaw">S.

It is integrated in the distribution management system. Voltage is an important parameter for the control of electrical power systems. The distribution network operators have the responsibility to regulate the voltage supplied to consumer within statutory limits. Traditionally, the On-Load Tap Changer (OLTC) transformer equipped with automatic voltage control (AVC) relays is the most popular and effective voltage control device. A static synchronous compensator (STATCOM) may be equipped with several controllers to perform multiple control functions. Static Var Compensation (SVC) is regulation slopes and available margins for var dispatch. The voltage control in distribution networks is established as a centralized analytical function in this paper. </p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Voltage%20Control" title="Voltage Control">Voltage Control</a>, <a href="https://publications.waset.org/search?q=Reactive%20Power" title=" Reactive Power"> Reactive Power</a>, <a href="https://publications.waset.org/search?q=Distribution%20System." title=" Distribution System."> Distribution System.</a> </p> <a href="https://publications.waset.org/17072/technique-for-voltage-control-in-distribution-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/17072/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/17072/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/17072/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/17072/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/17072/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/17072/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/17072/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/17072/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/17072/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/17072/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/17072.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">9506</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">915</span> A High Precision Temperature Insensitive Current and Voltage Reference Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kimberly%20Jane%20S.%20Uy">Kimberly Jane S.

However for driving some piezoelectric actuator, arbitrary voltage not a pulse but a steady voltage should be applied. Piezoelectric load is considered as R-C load and its voltage does not decrease even though the applied voltage decreases. Therefore it needs some special inverter with circuit that can discharge the capacitive energy. Especially for unidirectional arbitrary voltage driving like as sine wave, it becomes more difficult problem. In this paper, a charge and discharge circuit for unidirectional arbitrary voltage driving for piezoelectric actuator is proposed. The circuit has charging and discharging switches for increasing and decreasing output voltage. With the proposed simple circuit, the load voltage can have any unidirectional level with tens of bandwidth because the load voltage can be adjusted by switching the charging and discharging switch appropriately. The appropriateness is proved from the simulation of the proposed circuit.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=DC-DC%20converter" title="DC-DC converter">DC-DC converter</a>, <a href="https://publications.waset.org/search?q=analog%20output%20voltage" title=" analog output voltage"> analog output voltage</a>, <a href="https://publications.waset.org/search?q=sinusoidal%0D%0Adrive" title=" sinusoidal drive"> sinusoidal drive</a>, <a href="https://publications.waset.org/search?q=piezoelectric%20load" title=" piezoelectric load"> piezoelectric load</a>, <a href="https://publications.waset.org/search?q=discharging%20circuit." title=" discharging circuit."> discharging circuit.</a> </p> <a href="https://publications.waset.org/9999059/a-study-on-unidirectional-analog-output-voltage-inverter-for-capacitive-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9999059/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9999059/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9999059/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9999059/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9999059/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9999059/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9999059/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9999059/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9999059/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9999059/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9999059.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">2520</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">913</span> SCR-Stacking Structure with High Holding Voltage for I/O and Power Clamp</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Hyun-Young%20Kim">Hyun-Young Kim</a>, <a href="https://publications.waset.org/search?q=Chung-Kwang%20Lee"> Chung-Kwang Lee</a>, <a href="https://publications.waset.org/search?q=Han-Hee%20Cho"> Han-Hee Cho</a>, <a href="https://publications.waset.org/search?q=Sang-Woon%20Cho"> Sang-Woon Cho</a>, <a href="https://publications.waset.org/search?q=Yong-Seo%20Koo"> Yong-Seo Koo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we proposed a novel SCR (Silicon Controlled Rectifier) - based ESD (Electrostatic Discharge) protection device for I/O and power clamp.

These characteristics enable to have latch-up immunity under normal operating conditions as well as superior full chip ESD protection. The proposed device was analyzed to figure out electrical characteristics and tolerance robustness in term of individual design parameters (D1, D2, D3). They are investigated by using the Synopsys TCAD simulator. As a result of simulation, holding voltage increased with different design parameters. The holding voltage of the proposed device changes from 3.3V to 7.9V. Also, N-Stack structure ESD device with the high holding voltage is proposed. In the simulation results, 2-stack has holding voltage of 6.8V and 3-stack has holding voltage of 10.5V. The simulation results show that holding voltage of stacking structure can be larger than the operation voltage of high-voltage application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=ESD" title="ESD">ESD</a>, <a href="https://publications.waset.org/search?q=SCR" title=" SCR"> SCR</a>, <a href="https://publications.waset.org/search?q=holding%20voltage" title=" holding voltage"> holding voltage</a>, <a href="https://publications.waset.org/search?q=stack" title=" stack"> stack</a>, <a href="https://publications.waset.org/search?q=power%20clamp." title=" power clamp."> power clamp.</a> </p> <a href="https://publications.waset.org/10001846/scr-stacking-structure-with-high-holding-voltage-for-io-and-power-clamp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10001846/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10001846/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10001846/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10001846/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10001846/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10001846/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10001846/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10001846/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10001846/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10001846/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10001846.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">2061</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">912</span> Analysis of SCR-Based ESD Protection Circuit on Holding Voltage Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Yong%20Seo%20Koo">Yong Seo Koo</a>, <a href="https://publications.waset.org/search?q=Jong%20Ho%20Nam"> Jong Ho Nam</a>, <a href="https://publications.waset.org/search?q=Yong%20Nam%20Choi"> Yong Nam Choi</a>, <a href="https://publications.waset.org/search?q=Dae%20Yeol%20Yoo"> Dae Yeol Yoo</a>, <a href="https://publications.waset.org/search?q=Jung%20Woo%20Han"> Jung Woo Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This paper presents a silicon controller rectifier (SCR) based ESD protection circuit for IC.

For some piezoelectric actuator applications, arbitrary voltage is required to actuate. Especially for unidirectional arbitrary voltage driving like as sine wave, some special inverter with circuit that can charge and discharge the capacitive energy can be used. In this case, the difference between power supply level and the object voltage level for RC load is varied. Because the control gain is constant, the controlled output is not uniform according to the voltage difference. In this paper, for charge and discharge circuit for unidirectional arbitrary voltage driving for piezoelectric actuator, the controller gain is controlled according to the voltage difference. With the proposed simple idea, the load voltage can have controlled smoothly although the voltage difference is varied. The appropriateness is proved from the simulation of the proposed circuit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Analog%20voltage%20inverter" title="Analog voltage inverter">Analog voltage inverter</a>, <a href="https://publications.waset.org/search?q=Capacitive%20load" title=" Capacitive load"> Capacitive load</a>, <a href="https://publications.waset.org/search?q=Gain%0D%0Acontrol" title=" Gain control"> Gain control</a>, <a href="https://publications.waset.org/search?q=DC-DC%20converter" title=" DC-DC converter"> DC-DC converter</a>, <a href="https://publications.waset.org/search?q=Piezoelectric" title=" Piezoelectric"> Piezoelectric</a>, <a href="https://publications.waset.org/search?q=Voltage%20waveform." title=" Voltage waveform."> Voltage waveform.</a> </p> <a href="https://publications.waset.org/10002587/performance-enhancement-of-analog-voltage-inverter-with-adaptive-gain-control-for-capacitive-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10002587/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10002587/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10002587/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10002587/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10002587/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10002587/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10002587/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10002587/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10002587/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10002587/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10002587.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">1751</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">908</span> Comparative Study of Line Voltage Stability Indices for Voltage Collapse Forecasting in Power Transmission System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=H.%20H.%20Goh">H.

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 used is 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> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Critical%20line" title="Critical line">Critical line</a>, <a href="https://publications.waset.org/search?q=line%20outage" title=" line outage"> line outage</a>, <a href="https://publications.waset.org/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/search?q=maximum%20loadability" title=" maximum loadability"> maximum loadability</a>, <a href="https://publications.waset.org/search?q=voltage%20collapse" title=" voltage collapse"> voltage collapse</a>, <a href="https://publications.waset.org/search?q=voltage%20instability" title=" voltage instability"> voltage instability</a>, <a href="https://publications.waset.org/search?q=voltage%20stability%20analysis." title=" voltage stability analysis."> voltage stability analysis.</a> </p> <a href="https://publications.waset.org/10000247/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/10000247/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10000247/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10000247/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10000247/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10000247/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10000247/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10000247/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10000247/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10000247/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10000247/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10000247.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">4163</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">907</span> Comparison of SVC and STATCOM in Static Voltage Stability Margin Enhancement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Mehrdad%20Ahmadi%20Kamarposhti">Mehrdad Ahmadi Kamarposhti</a>, <a href="https://publications.waset.org/search?q=Mostafa%20Alinezhad"> Mostafa Alinezhad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>One of the major causes of voltage instability is the reactive power limit of the system.

To verify its use, a simplified 4-bus test system is situated by assuming a three-phase fault at bus 4. As a result, the DSTATCOM can resume the load voltage to the desired level within 1.8 ms.

Performance of the proposed method is investigated under different types of voltage sags for linear and nonlinear loads. Simulation results show appropriate operation of the proposed control system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Custom%20power" title="Custom power">Custom power</a>, <a href="https://publications.waset.org/search?q=power%20quality" title=" power quality"> power quality</a>, <a href="https://publications.waset.org/search?q=voltage%20sagmitigation" title=" voltage sagmitigation"> voltage sagmitigation</a>, <a href="https://publications.waset.org/search?q=current%20vector%20control." title=" current vector control."> current vector control.</a> </p> <a href="https://publications.waset.org/14011/balanced-and-unbalanced-voltage-sag-mitigation-using-dstatcom-with-linear-and-nonlinear-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/14011/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/14011/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/14011/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/14011/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/14011/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/14011/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/14011/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/14011/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/14011/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/14011/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/14011.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">2836</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">902</span> Dynamic Voltage Stability Estimation using Particle Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Osea%20Zebua">Osea Zebua</a>, <a href="https://publications.waset.org/search?q=Norikazu%20Ikoma"> Norikazu Ikoma</a>, <a href="https://publications.waset.org/search?q=Hiroshi%20Maeda"> Hiroshi Maeda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Estimation of voltage stability based on optimal filtering method is presented.

The maximum efficiency is 92.4 % at output power to be 38.6 mW for 3.6 V input voltage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Wireless%20power%20transfer" title="Wireless power transfer">Wireless power transfer</a>, <a href="https://publications.waset.org/search?q=active%20diode" title=" active diode"> active diode</a>, <a href="https://publications.waset.org/search?q=delay%20compensation" title=" delay compensation"> delay compensation</a>, <a href="https://publications.waset.org/search?q=time%20to%20voltage%20converter" title=" time to voltage converter"> time to voltage converter</a>, <a href="https://publications.waset.org/search?q=PCE." title=" PCE."> PCE.</a> </p> <a href="https://publications.waset.org/10010178/an-active-rectifier-with-time-domain-delay-compensation-to-enhance-the-power-conversion-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10010178/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10010178/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10010178/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10010178/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10010178/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10010178/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10010178/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10010178/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10010178/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10010178/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10010178.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">773</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">895</span> Design of DC Voltage Control for D-STATCOM</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kittaya%20Somsai">Kittaya Somsai</a>, <a href="https://publications.waset.org/search?q=Thanatchai%20Kulworawanichpong"> Thanatchai Kulworawanichpong</a>, <a href="https://publications.waset.org/search?q=Nitus%20Voraphonpiput"> Nitus Voraphonpiput</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This paper presents the DC voltage control design of D-STATCOM when the D-STATCOM is used for load voltage regulation. Although, the DC voltage can be controlled by active current of the D-STATCOM, reactive current still affects the DC voltage. To eliminate this effect, the control strategy with elimination effect of the reactive current is proposed and the results of the control with and without the elimination the effect of the reactive current are compared. For obtaining the proportional and integral gains of the PI controllers, the symmetrical optimum and genetic algorithms methods are applied. The stability margin of these methods are obtained and discussed in detail. In addition, the performance of the DC voltage control based on symmetrical optimum and genetic algorithms methods are compared. Effectiveness of the controllers designed was verified through computer simulation performed by using Power System Tool Block (PSB) in SIMULINK/MATLAB. The simulation results demonstrated that the DC voltage control proposed is effective in regulating DC voltage when the DSTATCOM is used for load voltage regulation.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=D-STATCOM" title="D-STATCOM">D-STATCOM</a>, <a href="https://publications.waset.org/search?q=DC%20voltage%20control" title=" DC voltage control"> DC voltage control</a>, <a href="https://publications.waset.org/search?q=Symmetrical%20optimum" title=" Symmetrical optimum"> Symmetrical optimum</a>, <a href="https://publications.waset.org/search?q=Genetic%20algorithms" title=" Genetic algorithms"> Genetic algorithms</a> </p> <a href="https://publications.waset.org/7835/design-of-dc-voltage-control-for-d-statcom" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/7835/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/7835/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/7835/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/7835/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/7835/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/7835/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/7835/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/7835/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/7835/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/7835/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/7835.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">5038</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">894</span> Modeling and Analysis of SVPWM Based Dynamic Voltage Restorer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Ahmed%20Helal">Ahmed Helal</a>, <a href="https://publications.waset.org/search?q=Sherif%20Zain%20Elabideen"> Sherif Zain Elabideen</a>, <a href="https://publications.waset.org/search?q=Ahmed%20Lotfy"> Ahmed Lotfy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper the modeling and analysis of Space Vector Pulse Width Modulation (SVPWM) based Dynamic Voltage Restorer (DVR) using PSCAD/EMTDC software will be presented in details.
