摘要
500kV变电站备用电源自投是提高电网供电可靠性和保证电网安全运行的一项重要措施。为此,分析了500kV变电站备用电源自投装置的功能技术要求,提出了设计原则和安全运行注意事项,并介绍了其在广东电网的应用成果。
Automatic closing-in of reserve power supply for 500 kV substations is an important measure to improve the power supply reliability and ensure the safe operation of power grid. This paper analyzes the function and technical requirements of the automatic stand-by power switching device for 500 kV substations, puts forward the design principle and points for attention in operation, and describes its application results in Guangdong power grid.
