摘　　要：风力发电场中的集电线路主要采用直埋电缆型式,受弧光接地过电压影响的问题越来越突出,而风力发电系统中弧光接地过电压的限制方法和常规电网不尽相同。详细阐述了弧光接地过电压的产生机理和主要表现,并对风力发电系统中的几种弧光接地过电压限制方法进行了总结和研究,结合实际工程给出了比较和说明。The collector lines in wind farms are mainly buried cable type,so Arc Earthed Overvoltage appears to be more and more prominent and the eliminating methods for Arc Earthed Overvoltage in wind power generation are different from the general methods.This article elaborates the mechanism and main performance of Arc Earthed Overvoltage,and several eliminating methods in wind power generation are studied,finally,comparison and description are illustrated based on practical engineering.
