| 摘 要： | 研究了由双馈感应式发电机和笼型异步发电机组成的风力发电系统的暂态电压控制策略。当电网发生故障时,单位功率因数运行方式下的双馈感应式发电机组和笼型异步发电机组都不能够提供无功功率以帮助系统恢复稳定运行。本文提出了一种基于PI控制器的暂态电压控制策略并对其进行仿真分析。仿真结果表明,故障清除后能够提高双馈感应式发电机和笼型异步发电机的暂态电压稳定性,同时改善了系统稳定运行的能力。

| Abstract: | Transient voltage control strategy of wind power system composed of doubly-fed induction generator(DFIG) and squirrel cage induction generator(SCIG) is studied in this paper.The DGIG based on the unity power factor operating mode and the SCIG can not provide reactive power to help power system to recover stable operation under fault in grid.The transient voltage control strategy based on PI controller is presented simulated and analyzed in this paper,Simulation results show that when power system fault is c... |
