Aiming at a wide range and high-frequency reactive voltage fluctuation problem in 750kV power grid which due to large-scale wind power, a coordinated control strategy of a multiple FACTS (Flexible Alternative Current Transmission Systems) configuration is investigated in the paper. System-level and electromagnetic transient level control method of multiple FACTS devices are proposed in the small wind power fluctuation, big disturbance and off-grid level, and the priorities and the principles are determined. The strategy is applied to “Xinjiang and Northwest 750kV main grid interconnection second channel project”, and the correctness and effectiveness is proved.
