站用电双路电源自动切换方案分析

Analysis of Automatic Switching Scheme for Dual Power Supply in Substation

通过介绍变电站站用电系统在实际运行中发生的几个故障案例,分析几种常用的站用电双路电源自动切换方案,研究双路电源自动切换方案适用的供电环境及其在应用中存在的缺陷,提出站用电双电源互为备用的自动切换方案,旨在提高站用电系统运行的可靠性。

In this paper,several automatic switching schemes of dual power supply are analyzed,which is based on several fault cases of substation power system in actual operation.It studied the application environment and defects of the scheme,A auto matic switching scheme is achieved by mutual standby of double powers,which is proposed to improve the reliability of substation power system.
