استفاده از انرژی باد برای تولید انرژی الکتریکی طی سال های اخیر از رشد چشمگیری برخوردار بوده است. با افزایش نفوذ توربین?های بادی در سیستم های الکتریکی، بررسی پایداری نیروگاه های بادی و تأثیر آنها بر روی عملکرد کل سیستم، اهمیت زیادی پیدا کرده است. تاکنون روش هایی که به منظور بهبود پایداری گذرا و دینامیکی نیروگاه های بادی صورت گرفته، عبارتند از: تزریق توان راکتیو، تغییر مقادیر مقاومت و راکتانس های...
The STATCOM (Synchronous Static Compensator) based on voltage source converter (VSC) is used for voltage regulation in transmission and distribution system. The STATCOM can rapidly supply dynamic VARs required during system faults for voltage support. Strict requirements of STATCOM losses and total system loss penalty preclude the use of PWM (Pulse-Width Modulation) for VSC based STATCOM applic...
In this modern world, the electrical power consumption is vast and its power system is complex and faces many challenges due to growing demand and construction of new lines. Transient stability is one of the main system insecurity when large disturbances occur. Here at first conventional shunt facts devices Static VAR Compensator (SVC), Static Synchronous Compensator (STATCOM)are used as an add...
This study inspects the optimum location of STATCOM device in long transmission line to acquire the maximum power system transient stability improvement. STATCOM is a kind of prominent and effective shunt FACTS device which is used in power system to enhance the power system stability and to regulate the line voltage. When it has been placed at the center point of a transmission line, play a ke...
This paper proposes Fuzzy Logic Based STATCOM. It regulates the voltage at the point of common coupling (PCC) by injecting reactive power. This device also plays a vital role in enhancing stability for small and large transient disturbances in power system. Simulations using MATLAB / SIMULINK are carried out to verify the performance of STATCOM using fuzzy controller. The result shows that fuzz...
Providing Additional Advantages for STATCOM in Power Systems by Integration of Energy Storage Device
The use of Flexible AC Transmission System (FACTS) devices in a power system can potentially overcome limitations of the present mechanically controlled transmission system. Also, the advance of technology makes possible to include new energy storage devices in the electrical power system. The integration of Superconducting Magnetic Energy Storage (SMES) into Static Synchronous Compensator (STA...
Static Synchronous Compensator (STATCOM) is a device capable of solving the power quality problems at the power system. These problems happen in milliseconds and because of the time limitation, it requires the STATCOM that has continuous reactive power control with fast response. In this way, optimal exploitation of STATCOM by classical controllers has been a controversial issue in reputable jo...
Abstract: Artificial neural network (ANN) control of static compensator (STATCOM) to improve the damping of power systems is presented. The proposed control strategy is applied on a STATCOM attached to a single machine-infinite bus (SMIB) and a multi-machine power systems that include a superconducting generator (SCG). The proposed control method, ANN-STATCOM is designed based on proportional i...
The Static Var Compensator (SVC) and the Static Synchronous Compensator (STATCOM), as two components of Flexible AC Transmission System (FACTS) devices, play an important role in controlling the reactive power flow to the power network. Because of economic considerations, identifying the best location for installing the SVC and STATCOM is also important. The FACTS devices placement problem is c...
در سال های اخیر با توجه به رشد روز افزون شبکه قدرت، استفاده از سیستم های انتقال انعطاف پذیر ac، (facts) جهت حداکثر کردن ظرفیت انتقال خطوط موجود به همراه بالا بردن پایداری سیستم های قدرت افزایش یافته است. جبران کننده های استاتیکی (statcom) یکی از انواع ادوات facts می باشند که با کنترل توان راکتیو، در محل نصب، عمل تنظیم ولتاژ باس را انجام می دهند. ناپایداری ولتاژ بیشتر بر اثر نامتعادلی توان راک...
