为了增强风电场并网运行的可靠性，提出了在风电场送出线路投入单相重合闸。先对故障时风电机并网电压进行理论计算，然后结合故障时的实际录波结果，对比分析了在故障时风电机并网电压的跌落情况。根据规程对风电机低电压穿越的要求，以及风电场内低电压保护的配置，论证了乌江源风电场220 kV 送出线路投入单相重合闸的可行性，为提高乌江源风电场并网运行的可靠性奠定基础。

In order to enhance wind farm reliably running, setting single-phase reclosure at transmission line of wind farm is proposed. Firstly, the paper finished theoretical calculations about the running voltage of wind turbine generator at fault state. Then, according to the results of fault recording, the paper contrasted and analysed the voltage drop state of wind turbine generator at fault condition. Ac-cording to the requirement for low voltage ride through of regulations and low voltage protection configuration of Wujiangyuan Wind Farm, the feasibility of setting single-phase reclosure at 220 kV transmission line of the wind farm is demonstrated, and this laid a foundation for raising reliabile running of the wind farm.
