Abstract:
This paper deals with model, simulates and develop a multi area system with and without fault. So as to carry out improvement in power system stability during heavy load condition, by adding STATCOM controllers. The main contribution of this paper is (i) use of STATCOM to enhance transient stability and produce better voltage regulation (ii) analyzing the application of nonlinear control theory for stabilizing controller in a closed loop system. PI and fuzzy controller are used for controlling the STATCOM and the simulation results are obtained. The results indicate that there is improvement in the response of the closed loop system by using fuzzy logic controllers. The simulation results are validated setting up a prototype.
