中文摘要：
研究分析了恒速异步风力发电机、双馈感应风力发电机和直驱永磁同步风力发电机组成的风电场的频率响应特性;利用DIgSILENT/PowerFactory建立了风电场的动态模型;通过仿真显示：由于采用解耦控制方式,基于双馈感应电机、直驱永磁同步电机的变速风电机组不能对系统频率变化做出快速有效响应,而基于异步感应电机的恒速风电机组能快速地对系统频率变化做出正确响应,能有效地提高系统的频率稳定性。
英文摘要：
The wind turbine＇s frequency response characteristics have been studied on fixed speed in-duction wind turbines,double-fed induction wind turbines and direct-drive permanent magnetic wind turbines,the dynamic model of wind farm is build by using DIgSILENT/PowerFactory,by the simulation,the frequency response characteristics of the three kinds of wind turbines have been analyzed,the con-clusion are as following,the double-fed induction wind turbine,direct-drive permanent magnetic wind turbine can not response to system frequency change effectively due to using decoupling control method,on the other hand,the fixed speed induction wind turbine can response fast and correctly to power system frequency change,this could improved the systems frequency stability effectively.
