Power systems are changing rapidly because of deregulation, fast demand rising and wide area expansion. Controllability and stability of power systems can be improved by proper use of FACTS devices. STATCOM is one of the parallel FACTS devices that can be used for power system transient, steady state and dynamic stability. In this research, proper control and application of STATCOM is studied for improving power system transient stability. Fuzzy logic is used to overcome the existing uncertainties and complexities of the system. The controller is designed, based on different input signals, and the results are studied by simulation results.
