摘要

文中将风电场接入规范定义的低电压穿越特性引入到风电场集电线路电流保护的动作特性中，提出了电流保护动作特性等价的风电机组低电压穿越能力评价指标——低电压穿越容量百分比系数，量化分析了Ⅰ段和Ⅱ段电流保护动作特性等价的低电压穿越容量，提出了提高电流保护等价低电压穿越容量的改进措施。

Abstract

Access criteria of lower voltage ride through capability of wind generators in wind farms is introduced into operation characteristics of overcurrent protection in power collection lines. Percentage coefficient in the evaluation model of low voltage ride through capability to overcurrent protection is proposed， and the equivalent low voltage ride through capability from zone I and zone II relay are quantified， the improvement measures are also proposed.
