doi:10.11985/2018.01.004

Abstract

Abstract:

According to the IEEE SSR first benchmark system, proposed to suppress sub synchronous resonance controllable series compensation (TCSC) scheme. By using PSCAD/EMTDC simulation software, the establishment of TCSC and its control simulation model, simulation study can suppress sub synchronous resonance with controllable series compensation and fixed series compensation combination scheme. By using open loop impedance control strategy of TCSC the performance of inhibiting sub synchronous resonance simulation.

Key words: Thyristor controlled series compensation, sub-synchronous resonance, series compensation
