This paper deals with PID compensator control of Synchronous Rectifier (SR) Buck Converter to improve its conversion efficiency under different load conditions with the help of a Zero Voltage Switching(ZVS)Logic Circuit. Since the freewheeling diode is replaced by a high frequency switch MOSFET in this buck configuration, the SR control technique itself will be sufficient under heavy load condi...

The most difficult aspect of optimizing a wind farm is creating an accurate model, especially if the connected to grid. inconsistency and unpredictability speeds exacerbates this issue. When dealing with farms, it possible that reactive power addition capabilities individual turbines are insufficient meet network requirements. This due cable losses line between PCC. study employs doubly fed ind...

In this paper, the optimal location and tuning parameters of Static Var Compensator (SVC), Proportional-Integral-Derivative (PID) stabilizer with low pass filter and Thyristor Controlled Series Compensator (TCSC) controllers using multi objective Honey Bee Mating Optimization (HBMO) to damp small signal oscillations in a multi machine power system has been implemented. Whereas, the performance ...

Improving transmission lines (TL) steady-state stability limit can be achieved by Static Synchronous Series Compensators (SSSC) that work as a converter-based compensator. The modification of the SSSC function to inject both active and reactive power into TL improves its performance according different indices. improvement indices include reduction losses, enhancement dynamic margin voltage pro...

The wind power generation has become more important nowadays to meet the increase in demand. DFIG based is recent and used many countries due its better controllability. controllers like Proportional Integral (PI) are for stabilization of waveforms supply system. change produces oscillation damping days. effect varying input generate using turbine resulting instability system because control do...

This paper presents the impact of the Static Synchronous Compensator (STATCOM) on the performance of distance protection of EHV transmission lines. A 400kV transmission system having midpoint connected STATCOM with its control circuit is modeled using MATLAB/SIMULINK software. The impact of STATCOM on distance relay for different fault conditions and different fault locations is analyzed. Simul...

Flexible ac transmission systems (FACTS) controller can provide better control than conventional control and achieve fast control response time. Static synchronous compensator (STATCOM) is one of the key FACTS devices based on voltage source converter (VSC) technology whose capacitive or inductive output current can be controlled independent of the ac system voltage. In this review paper, the a...

This work investigates the effects of the STATCOM (Static Synchronous Compensator), a FACTS (Flexible AC Transmission Systems) device, on small-signal power system angle stability. This investigation is carried out for a single machine connected to an infinite bus via a loss-less transmission line. The study is based on investigation of the eigenvalues of the linearized power system model in th...
