| Abstract: | Aimed at the application of MW level direct-drive wind power generating system, one permanent magnet synchronous generator (PMSG) compound vector control scheme based on stator current orientation is proposed in this paper. Between the cut-in speed and turning speed of generator, the scheme adopts the maximum ratio of torque to current control mode to advance the system generating power, and uses the flux-weakening control of maximum power output between the turning speed and limiting speed, to improve the system stability. According to the real time monitoring generator operating status, two control strategies mentioned above can transform each other. Accuracy and feasibility of the proposed scheme used in the MW level PMSG control system have been proved by the simulation and experiment. |
