In this paper, the advancement in small signal stability via the optimal placement of Static Synchronous Compensator (STATCOM) and its performance is considered. The Eigen values are employed to analyze the stability of the WSCC system and the analysis has been done by PSAT software. It has been studied through light, medium, heavy, heavy one loading conditions unlike the existing system. At heavy one loading condition, the stability of the system collapses and the system has positive Eigen values. The system with STATCOM has the ability to work with stability though it undergoes heavy one loading conditions compared to the system without STATCOM and the positive Eigen values in the system is nil. The outcome of the proposed approach shows that STATCOM enhances the small signal stability excellently in the power system network.
