给出了双馈风电机、无功补偿装置SVC与STATCOM模型，并对这两种无功补偿装置分别提出了相应的控制策略。结合蒙东某一地区实际电网，仿真分析了将SVC与STATCOM这两种无功补偿装置分别应用到该地区风电场中的暂态电压特性。结果表明SVC与STATCOM均能帮助风电场在电网故障后快速重建电压，且相比之下STATCOM能更好地提高系统的暂态电压稳定性，补偿效果优于SVC。

The models of doubly-fed wind turbine, SVC and STATCOM were given. And the control strategies of the two dynamic reactive power compensation devices were provided respectively. Based on a regional power grid of Mengdon, both SVC and STATCOM were applied to the wind farm respectively in simulation and the characteristics of transient voltage were analyzed. The simulative results showed that both the SVC and STATCOM could help wind farm voltage rapidly reconstruct after the fault. In addition, the STATCOM could improve the transient stability of the wind farm preferably, and the compensation effect of STATCOM was better than SVC.
