摘要
为了减小风电并网对电力系统的影响,开展关于静止无功补偿器对风电并网过程影响的仿真分析。在研究鼠笼异步风力发电机组和静止无功补偿器(SVC)的基础上,利用PSCAD软件搭建了含有鼠笼型风电场的系统模型,并对风电场并网点在有无SVC时,系统发生瞬时三相短路故障的情况的出口电压进行仿真。通过对仿真结果进行对比分析,表明在风电系统中加入无功补偿装置后,其对(瞬时故障时)系统的恢复能力和抑制电压跌落有很大的改善作用。
In order to reduce the influence from wind power integration on power system, simulation analysis on static Var compensator（SVC） is carried out. Squirrel cage induction wind turbines and SVC are researched. System model which contains the squirrel cage wind farm is built by PSCAD software. In case of presence or absence of the SVC, when instantaneous three-phase short-circuit fault occurred, the outlet voltage is simulated. The results show that the SVC can greatly improve the ability of recover from transient fault and restrain voltage drop.
