摘　　要：将SVC应用于交直流混合输电系统能够有效抑制故障后电压振荡,缩短故障恢复时间,提高交直流混合输电系统电压稳定性。通过PSCAD/EMTDC建立了仿真模型,通过相互比较找出SVC的最佳控制方式,验证了SVC对交直流系统电压特性的改善作用,设计出进一步改善电压特性的基于SIMPLEX算法的SVC附加控制器。The application of SVC to AC/DC transmission system can improve the system voltage stability by inhibiting its voltage oscillation and shortening its recovery time. This paper constructs simulation model based on PSCAD/ EMTDC. Through comparison, the optimal SVC control method is identified, and the SVC effects on improving AC/ DC system voltage characteristics are verified＇. Finally, SVC supplementary controller is designed based on SIMPLEX algorithm in order to improve the system voltage stability further.
