平衡电网故障下双馈感应发电机的改进去磁控制

Doubly-fed induction generators are one of the most popular machines for variable-speed wind turbine. However, they are very sensitive to grid fault since the stator is directly connected to the grid. This paper analyzes the low-voltage ride-through performance of a doubly-fed induction generator-based wind turbine under balanced grid fault. An improved demagnetization control, immune to system pa...
