附加阻尼控制SVC在双馈型风电场中的应用研究

Research on the application of supplementary damping control SVC in wind plant based on DFIG

将附加阻尼控制SVC应用于兆瓦级双馈型风电场并网系统,在此基础上研究了系统的暂态过程。首先建立了双馈风电机组的动态模型,水轮发电机组以及附加阻尼控制SVC的数学模型,然后仿真研究了双馈型风电场并网以后对区域系统暂态过程的影响,对比分析了风电场接入和故障情况下采用普通SVC和附加阻尼控制SVC的作用和效果,仿真结果验证了建立模型和采取方法的正确性和有效性。

Supplementary damping control SVC is applied in an MW wind plant based DFIG integration on power system and transient process of the system is studied in this paper. In the process of analyzing,the dynamic models of wind turbines based on doubly-fed induction generator,and the mathematical models of hydraulic turbine and supplementary damping control SVC is estab- lished.Through the simulink research,transient process of regional system is studied. Under situations of system fault and an MW wind plant access,different effects of generic SVC and supplementary damping control SVC are analyzed comparatively and the simulation results verify the models and methods are correct and effective.
