摘要
建立了普通异步风力发电机组、尾流效应、STATCOM的模型,仿真分析了四种风速模型、尾流效应、短路故障、无功补偿等因素对风电场接入系统后的暂态稳定性影响。仿真结果表明,渐变风和阵风对其暂态特性影响较其他两种风大,尾流效应降低了风电机组对风能的利用率,STATCOM提高了系统的暂态电压稳定性。
Establish asynchronous wind generator model, wake effect model, STATCOM model. Simulate and analyze the impact of four wind models, wake effect, short circuit, reactive power compensation factors acted on system transient stability, after a wind farm injected the grid. The results of simulation show： the gradient wind and gust wind are more influencing on system transient characteristic than the other two. Wake effect can reduce the utilization of the wind turbines on wind energy. STATCOM improves the transient vohage stability.
