摘　　要：分析、总结了SVC、STATCOM的结构、原理和控制方式,利用PSCAD分别搭建了SVC和STATCOM的模型,并结合异步风电机组系统应用,针对风速波动和接地故障时的无功补偿性能进行仿真和验证。结果表明,STATCOM在无功补偿性能上要优于SVC,但控制方式更加复杂,成本也更高。在实际工程中,根据工程预算和实际系统状况来综合比较,确定合理的补偿方案。This paper analyzed and summarized the structure, working principles, and control strategies of SVC and STATCOM. Then their models were constructed in PSCAD and combined with the wind farm model using induction generators to simulate their effects of reactive power compensation when the wind is fluctuating or a ground fault is occurred. The results show that STATCOM has better compensating performance than SVC, but it is more expensive and more intricate in control strategies. In the actual project, a reasonable compensation plan is determined by the project budget and actual system conditions.
