Improving transient stability of power system by using Distributed Static Series Compensator

Maintaining synchronous and stable operation in interconnected power system at minimum cost is complex problem. To ensure the continuous supply of electricity all synchronous generators must remain in synchronism during abnormal conditions also. In this work, Distributed Static Series Compensator (DSSC) is used to maintain required transient stability in power system during severe three-phase to ground fault and, it is found that DSSC is capable of maintaining synchronous operation in a considered two machine power system along with power system stabilizer as a supplementary controller.
