بهبود پایداری ولتاژ در سیستم چند باند با استفاده از جبران کننده سری سقفی استاتیک

Today's power system has become more complex due to open access electricity market activities and a increasing demand, for such network stability is an important issue. Among various types of stability, voltage instability and collapse become a concern problem all over the world. To maintain power system stability issues FACTS devices are used. In this paper a suitable approach to enhance the voltage stability of power system using static synchronous series compensator (SSSC) is studied. IEEE 4 bus system and IEEE 9 bus system is simulated using MATLAB Simulink software to study voltage stability and reactive power compensation. The performance of SSSC on voltage profile is analysed for multibus system. Simulation results demonstrate that voltage stability can be improved using of static synchronous series compensator.
