摘　　要：传统的基于同步发电机故障电流的分析方法已不能直接用于风电机组。建立正确的风力发电机仿真模型,分析风电场接入电力系统后故障电流特征及对继电保护的影响,对于改进和研发适用于风电场的继电保护具有重要意义。Traditional analytical methods based on the fault current of synchronous generator could not be used in wind turbines directly. The correct wind turbine model was built,and the characteristic of fault current and its effect on relay protection when wind power is connected to power system was analysed,which is of significance for improving and researching on relay protection of wind farm.
