The series compensation transmission system of GUOHUA JINJIE POWER PLANT is a typical station to grid,long distance and large capacity transmission mode. Because of higher series compensation level,SSR has been practical problem which becomes threat to the power system stability and operation safety. Based on the series compensation transmission system of JINJIE POWER PLANT, this paper deeply analyses SSR damping characteristic and risk of failure, focuses on SSR suppression scheme based on SVC and checks its effectiveness with the eigenvalue analysis and the electromagnetic transient time-domain simulation.
