摘　　要：对于故障中出现的相关负序分量,使用双同步旋转坐标系,对正序电流和负序电流分别进行相对独立的控制,同时在此基础上引入电网电压前馈的办法。此办法得到了仿真和实验的双重验证,保障了运行的可行性和有效性。The double synchronous rotating coordinate system is used for the correlated negative sequence components appearing in the fault.The positive sequence current and the negative sequence current are controlled independently.At the same time,the feedforward method of grid voltage is introduced.This method has been verified by simulation and experiment,which ensures the feasibility and validity of the operation.
