POWER SYSTEM STABILITY IMPROVEMENT USING (SSSC)

Abstract

This present the model of STATCOM which controllers the rotor angle deviation, voltage stability, transient stability for the improvement of power system stability. The development of the Morden power system has led to increase the complexity in the study of power system and also present new challenges to power system. The stability plays an important role to ensure the stable operation of power system in the occurrence of large disturbances and faults. The role of STATCOM will be mitigate the voltage problem like voltage sag, voltage swell which are generally occurs in power system during high voltage and low voltage condition. A power system network is considered which is simulated in phase simulation method and the network is simulated in 3 steps i.e. with and without STATCOM and with PSS. When the load increases suddenly the system has been disturbed so for greater performance STATCOM will be used.
