| 摘 要： | 为了研究包含恒速异步风力发电机和双馈异步风力发电机的风电场对电网的影响，应用Matlab 7.0建立了含不同风电机组的风电场动态模型。分析了风电场对电网暂态稳定性的影响，风电机组电压恢复情况，有功、无功变化情况，以及不同风电机组的低电压穿越能力。仿真结果表明：双馈异步风力发电机变速平稳、低电压穿越能力较强，有利于优化电能质量；当电网发生故障时，应针对不同的风电机组采取不同的控制策略以提高电力系统稳定性。

| Abstract: | To research the influence of wind farm consisting of fixed speed induction wind turbines and doubly fed induction wind turbines on power grid, by use of Matlab 7.0 a dynamic model of wind farm containing various wind turbine generators is built. The influence of wind farm on power system transient stability, the voltage recovery of wind turbine generators and the variation of active and reactive power as well as low voltage ride-through (LVRT) ability of different wind turbine generators are analyzed. Simulation results show that the smooth speed varying and strong LVRT of doubly fed induction wind power generator are be favorable to power quality optimization, and different control strategies should be adopted for different kinds of wind turbine generators to enhance power system stability. |
