摘要
随着并网风电容量的增大,风电在电力系统中比重的增加,为研究风力发电系统的稳定性,采用电力系统仿真软件DIgSILENT/PowerFactory对恒速和双馈感应两种异步风电机进行建模仿真,分析其在短路故障时不同风电机组及电气参数对系统恢复稳定的影响。结果表明:双馈感应风电机的故障动态响应比较敏感,具有明显优势。
With the increase of grid-connected wind power capacity and the proportion of wind power in the power system,in order to study the stability of wind power generation system,two kinds of asynchronous wind turbines,constant speed and double feed induction,are built by using electric power system simulation software DIgSILENT/PowerFactory. The effects of different wind turbines and electrical parameters on the recovery of the system are analyzed. The results show that the dynamic response of the doubly-fed induction wind turbine is sensitive and has obvious advantages.
