一起10kV配电网合环失败原因分析与应对措施

10kV配电网络合环时，合环线路功率潮流有可能发生很大变化，从而可能导致设备过负荷甚至断路器跳闸。通过对一起10kV配电网合环失败的实例，从合环后合环线路上功率潮流的变化分析了合环失败的原因，通过计算，验证了分析的正确性，并基于分析与计算，提出了具体应对措施。

Analysis on the Cause of a Looping-in Operation Failure in 10 kV Distribution Network and Its Coping Measures

During a looping-in operation of 10 kV distribution network,the power flow in the looped line could be greatly changed,which may cause the overload of equipment or even the trip of breaker.This paper analyzes the cause of looping-in operation failure based on the changing of the power flow in the looped line.The analysis is proven correct through calculation and the prevention measures are suggested on the basis of this analysis and calculation.
