Reviews of the performance of fuzzy controller to improve sustainability in the mamdani’s type of transient in SVC electric power systems

In this paper the structure of the model and practice of SVC (one of the small FACTS) we offer and we show that the fuzzy logic controller with use of the equipment has been used, since the FACTS of transient stability in power system data will be improved. Membership functions of fuzzy controlling this by a conventional PI control is controlling. Simulations made in two sections, one of which is the machinefinally, the bass is connected and the other in a symmetrical line will be fed from both sides and the two regions, suggests that the system of transient is a perfect stability. In the model presented in the middle of two located in the SVC, and fluctuations in the local area of the transient between damping and in this way we will show that the fuzzy logic control of transient stability for an improvement in the power system will be.
