站用电失压事件的分析与整改建议

The analysis and rectification suggestions on a power loss event of station

站用电系统作为变电站站用交流系统、直流系统的电源,是保障变电站安全、稳定运行的重要环节。本文结合一起0.4 kV站用电失压事件,分析系统电压波动导致站用电失压的过程,总结了站用变失压时的处理流程,并进一步说明执行取消站用变低压侧380 V开关低压脱扣反措以防范类似事故事件的发生的重要性。

As the power supply for the AC system and the DC system of substation,the station power system is an important link to ensure the safe and stable operation of substation.This article combined with a 0.4 kV station power loss event,analysis system voltage fluctuations lead to station power loss process,summarized the station when the loss of power in the processing process,and further explain the implementation of abolished station with low voltage side 380 V switch low-voltage tripping counters the importance of preventing the occurrence of similar incidents.
