Coordinating control method to improve LVRT ability of PMSG

The paper firstly models the Permanent Magnet Synchronous Generation System (PMSG) and analyzes the low voltage problem. Based on the traditional vector control strategy, the paper performs combining grid-side reactive power compensation control strategy, the DC voltage reference value correcting controller and the pitch angle control strategy. Finally, the effect of the above control strategy is verified by the simulation study. Through the above control strategy, the difficulty of system control is greatly reduced.
