摘要

随着一些地区风电供应比例的急剧增加，大规模风电场对地区电网稳定性造成的影响愈发显著。风力发电机的低电压穿越（LVRT）技术越来越受关注。文中首先介绍了低电压穿越技术的概念、国外的相应标准，继而分析比较了有关此技术的双馈感应发电机建模问题、各种常见的实现低电压穿越的技术手段及改进控制策略。最后描述了具备此技术的风电场对电力系统的影响。

Abstract

With the wind power supply sharply increasing in some areas， the effects of large scale wind farms on the stability of regional power system are becoming very remarkable. Accordingly， more and more studies are focusing on the low voltage ride through（LVRT） technology used for doubly fed induction generators（DFIGs）. In this paper， the LVRT concept and relevant international standards are first introduced. And then it introduces various modeling methods， popular LVRT technologies and improved control strategies. In the end， the effects of wind farms with LVRT capability on the power systems are analyzed.
