摘要 对基于正负序同步旋转坐标系的双馈电机控制方程进行适当推导,得到一种传统励磁策略+辅助负序励磁策略的转子电流控制方案。在不平衡电网下,以控制平衡的定子电流为目标,通过PSIM仿真和风场实验验证方案的可行性。 DFIG control function was deduced based on positive and negative sequence synchronous rotating frame, and a novel control strategy of rotor current was obtained, which consists of the conventional excitation scheme and auxiliary negative sequence control scheme. The target was control balanced stator current under unbalanced grid condition, the proposed control strategy was verified using PSIM simulation and wind power plant experiment.
