Power system reliability enhancement using a thyristor controlled series capacitor

This paper examines the impact of a thyristor controlled series capacitor (TCSC) on power system reliability. In this application, the TCSC is employed to adjust the natural power sharing of two different parallel transmission lines and, therefore, enable the maximum transmission capacity to be utilized. In this context, a reliability model of a multi-module TCSC has been developed and incorporated in the transmission system. The results of the investigations show a significant improvement system reliability when utilizing the improvement is measured using the two indices of loss of load expectation (LOLE) and loss of energy expectation (LOEE)
