Abstract

This paper deals with analysis of the detailed dynamics of the thyristor controlled series compensator (TCSC). The system considered is a system of one machine connected to an infinite bus through a thyristor controlled series compensated transmission line. This system can be described as periodic state equations. This paper provides analysis of the periodic state equations using the state variable approach. Transient characteristics as well as steady state characteristics of the TCSC are presented using the analytical equations for three operating modes of the TCSC. The simulations are performed using the MATLAB program
