| 摘 要： | 对VSC-HVDC联结2个交流有源网络时的运行特性进行分析,建立了VSC-HVDC系统的模型,在此基础上根据系统所要完成的功能确定对两个VSC的控制策略,对控制系统中的具体环节进行了设计。通过交流故障实验波形分析了VSC在系统故障时提供无功功率并稳定电压的作用。

| Abstract: | This paper analyzes VSC-HVDC operation properties when connecting two active AC systems,and establishes the model for VSC-HVDC system.Thereby the control strategy for the two VSCs is determined based on the functions to be performed by the system,and the specifics of the control system are designed.Through the tested AC fault waveform,analysis is made on VSC effect on providing reactive power and reinforcing voltage stability in the case of system failure. |
