应用TCSC抑制电力系统次同步谐振的研究

Suppression of Subsynchronous Resonance in Power System by Using TCSC

针对IEEE次同步谐振第一标准测试系统，提出抑制次同步谐振的可控串补（TCSC）方案。利用PSCAD／EMTDC仿真软件，建立TCSC及其控制仿真模型，仿真研究得到能抑制次同步谐振的可控串补和固定串补组合方案。采用开环阻抗控制策略对TCSC抑制次同步谐振的性能进行仿真验证。

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.
