摘　　要：常规风电机组由于有功、无功解耦控制,不能响应电网扰动。同步发电机组具有调速系统、励磁系统能够维持电网频率、电压稳定。通过设计调频、调压控制器,使风机对电网具有同步发电机的外特性。根据负荷的波动,调节风机输出的有功、无功功率,维持电网频率、电压稳定。建立了同步发电机、风电机组组成的电力系统仿真模型。Conventional wind turbines cannot respond to grid disturbance due to decoupling control of active and reactive power.Synchronous generator set has speed regulation system and excitation system to maintain the stability of power grid frequency and voltage.By adding the frequency and voltage regulation controller to wind turbine main control system, the wind turbine has external characteristics of synchronous generator.According to load fluctuation, the active power of wind turbine can be adjusted to maintain stability of frequency and voltage, and the grid stability can be enhanced effectively.A simulation model of power system consisting of wind farm, synchronous generator was developed.
