摘　　要：随着风电并网容量的比重不断增加,给电力系统的安全稳定带来一系列问题。尤其是当电网电压跌落时风力发电机组的低电压穿越能力的问题,已成为风电并网技术中的研究热点。结合风电机组的暂态过程,在对当前国内外研究成果进行分析和归纳基础上,总结了实现低电压穿越的不同技术原理和特点,为风力发电系统的低电压穿越技术的研究与应用提供参考。With the increasing proportion of wind power capacity into the grid, it is brought about a serious of questions to the security and stability of the power system. In particular, the low voltage ride-through ability of wind turbine when the grid voltage sag is the extensive research of the problem at present. Aiming at the present situation of the study of the subject, based on the research results at home and abroad, the different technical principlesand characteristics of LVRT were classified. Provide a reference for the subiect of LVRT research and avDlication.
