Abstract

Using the complex torque coefficient method realized by time domain simulation, the subsynchronous resonance (SSR) characteristics of power systems with static VAr compensators are studied in depth in this paper. The studied model is modified from the first IEEE Subsynchronous Resonance benchmark system added by a static VAr compensator (SVC), consisting of a thyristor-controlled reactor (TCR) and a thyristor-switched capacitor (TSC). A number of cases are studied by simulation through varying some key parameters of the model. By comparing the electric damping in different cases, the subsynchronous resonance characteristics of power systems with SVCs are identified.
