Analysis of the yimin-fengtun 500KV TCSC on the northast china power system

摘要

A TCSC (Thyristor Controlled Series Compensation) is proposed to be installed in the Yimin-Fengtun 500 kV system at the Fengtun site on the Northeast China power system which will be the first 500 kV series comensation of China. In this paper, amount of simulations are made to acquire characteristics of steady state and transient state of studied system. A comparison of system feature with the TCSC and fixed compensation is also given. An important point in the paper is about control strategy of the TCSC and influence of characteristics and parameters of the TCSC equipment on power system. It can be indicated that the TCSC can greatly improve the performance of power system nad characteristics of the TCSC equipment must be deeply studied so as to be fully used to acquire more benefit.
