| 摘 要： | 本文以抚州金巢变电站10kV配电网合环为例,基于电磁暂态仿真软件PSCAD/EMTDC准确地搭建了系统仿真模型,以解决配电网合环操作过程中可能出现的涌流现象引起保护误动作。提出在合环点两侧相位差较小时候合环,或者通过调整变压器分接头以减小合环点两端母线电压差,从而减小合环电流。

| Abstract: | In this paper,writer used 10KV distribution network closing loop operation,Jinchao Substation in Fuzhou and build accurately system simulation model based on the electromagnetic transient simulation software PSCAD/EMTDC to solve the protective malfunction which is caused by impact current phenomenon,which would affects the safety.We suggested close the loop while the phase difference on both sides of closing loop point smaller or decrease the closing loop current by adjusting the transformer taps to reduce the closing loop point voltage difference at both ends of bus. |
