摘要
就柔性直流输电对多端无源网络供电及其故障情况进行了简单的探讨。首先进行了系统模型的搭建;然后进行了控制器的设计、控制策略的选取;最后运用PSCAD软件进行了正常运行以及系统无源网络侧发生短路故障两种情况的仿真。仿真结果表明,建立的三端无源网络柔性直流输电系统,可以灵活地向无源网络输电,当发生故障时,也能较快恢复。
This paper briefly reviews the power supply and fault condition of VSC-Multi-Terminal Direct Current （VSC- MTDC） to passive network. Firstly, establish the system model; then design the controller and select the control strategy; finally simulate the normal operation and short-circuit fault occurring at the passive network side by using PSCAD. Simulation results show that the constructed VSC-MTDC system can flexibly supply power to passive net- work, and can recover quickly when the faults occur.
