Abstract

The modern trend is to employ FACTS devices in the existing system for effective utilization of existing transmission resources. These FACTS devices contribute to power flow improvement besides they extend their services in first-swing stability (Transient Stability) improvement as well. In this paper, in order to improve the Transient Stability margin further series FACTS device has been implemented and the results highlight the effectiveness of the application of a series FACTS device in improving the transient stability of a power system. In this paper, the studies had been carried out in order to improve the Transient Stability of WSCC 3Machine 9Bus System with Fixed Compensation on various lines and optimal location has been investigated using trajectory sensitivity analysis for better results. The results are experimented and simulated using MATLAB.
