详细归纳了不同类型风力发电系统的暂态仿真模型,研究了包括空气动力系统、风机轴系系统、桨距控制系统和变频器在内的动态仿真模型,以双馈风力发电机为例,研究了变桨距恒频/变速风力发电系统的控制系统模型。最后,在电力系统分析软件DigSILENT PowerFactory上分别对异步风力发电机、双馈风力发电机和全换相同步风力发电机进行建模,模拟变风速条件下不同类型风力发电机的动态特性。仿真结果进一步验证了所研究模型的正确性。
The paper summarizes transient simulation models in different wind power systems in detail,researches the dynamic simulation models including aerodynamic system,wind turbine shaft system,blade pitch control system and frequency converter.Taking double-fed wind turbine as an example,it researches the control system model of variable-pitch,constant-frequency/variable-speed wind power system.Finally,simulation modeling of asynchronous wind turbine,double-fed wind turbine and full phase changing synchronous wind turbine are performed with software DigSILENT PowerFactory.The dynamic characteristics of different types of wind turbines are simulated under variable wind speeds.The results verify the validity of simulation model mentioned.
