摘要
本文结合500kV变电站站用电系统的结构,分析站用电380V交流系统备自投失配故障及形成故障的原因,并提出了针对性的应对措施,提高站用电交流系统的可靠性;同时分析了站用电交流系统运行过程中的注意事项,进一步降低站用电交流系统故障的可能性,为站用电交流系统的安全稳定运行提供可靠保障。
Based on the structure of substation power supply system in 500 kV substation,this paper analyses the causes of the mismatch of standby self-switching and the causes of the faults in 380 V AC system for substation power supply,and puts forward corresponding measures to improve the reliability of the AC system for substation power supply.At the same time,it analyses the matters needing attention in the operation of the AC system for substation power supply,so as to further reduce the possibility of the fault It provides a reliable guarantee for the safe and stable operation of power station system.
