摘要
随着配电网自动化技术的逐步应用,配电网分支线开关保护装置也逐步取代以往的熔断器。为适应新的保护装置,基于架空线路的长度、变电站线路出口保护的配置与整定情况以及分支线路的位置,提出了一种配电网分支线保护的配置方案,从而防止在配电网分支线路故障时引起变电站线路出口保护跳闸导致整条馈线停电,提高供电可靠性;该分支线保护配置方案在杭州地区得到了应用,实际效果证明该方案达到了预期的效果。
With the gradual application of distribution network automation technology,branch line switch protection devices of the distribution network has gradually replaced the previous fuses.In order to adapt to new protection devices,based on the length of overhead lines,configuration and setting of substation line outlet protection,and location of branch lines,a configuration scheme for branch line protection of distribution network is proposed in this paper.It can prevent the protection tripping of the substation line,which leads to the power failure of the entire feeder,and can improves the reliability of the power supply.This branch line protection configuration scheme has been applied in Hangzhou area,and the actual results prove that the scheme has achieved the desired effect.
