风电场地埋电缆分接头故障处理及预防

Fault Treatment and Prevention of Buried Cable Tap in Wind Farm

根据中电联公布的并网口径数据显示,2013-2019年,我国风力发电并网装机容量呈逐年上升的趋势,其年复合增长率为20.94%。随着风机并网,风机装机容量的增加,电力电缆的电压等级也在不断提高。尤其风电场的地埋电缆,由于距离远,电缆分接头较多,一旦发生故障时,存在不易查找,需要耗费大量的人力、物力,并且根据故障时长会造成巨大的风机发电损失。文章主要针对南方某风电场项目中地埋电缆的常见故障处理以及相关的预防措施进行分析。

According to the grid connection caliber data released by China power grid,from 2013 to 2019,the grid connected installed capacity of China’s wind power generation is increasing year by year,with an annual compound growth rate of 20.94%.With the increase of installed capacity of wind turbine,the voltage level of power cable is also increasing.In particular,the buried cable of wind farm,due to its long distance and many cable taps,is not easy to fi nd in case of fault,which requires a lot of manpower and material resources,and will cause huge loss of wind turbine power generation according to the fault duration.This paper mainly analyzes the common fault treatment and related preventive measures of buried cable in a wind farm project in South China The solutions to the corresponding problems are proposed to reduce the outage loss of the wind farm.
