STABILITY IMPROVEMENT OF MULTIMACHINE USING STATCOM

Parul Taneja , Lakhwinder

In this paper, the effect of STATCOM for improving the stability of the multi machine power system is investigated. The STATCOM is used to control power flow of power system by injecting appropriate reactive power during dynamic state. Simulation results show that STATCOM not only considerably improves transient stability but also compensates the reactive power in steady state. Therefore STATCOM can increase reliability and capability of AC transmission system. To illustrate the performance of the FACTS controller (STATCOM), a three machine nine bus, Multi- Machine Power System has been considered.
