Abstract
In view of the problem of low voltage ride through of permanent magnet direct-drive wind power generation system, this paper improves the traditional control strategies, and increases power feed forward control in the machine side, according to the power difference of between the motor and the grid side to adjust motor-side active current quickly to control the torque of the generator, which achieves active power control of the generator.Grid-side convert-er tracks the grid voltage, outputs a constant reactive power according to the dropped level of the grid voltage to sup-port grid voltage recovery.The simulation showed that, the improved control strategy can stabilize the DC bus voltage quickly, which can achieve low-voltage ride through operation of wind turbines.关键词
