摘要
在变电站直流电源定期试验时的运行方式切换操作过程中,如何防止直流母线失电、保证供电安全是现场关注的重要问题。从一起220kV变电站直流母线失电的介绍,分析、探讨了该变电站直流母线失电的原因,并提出了解决方案。所提方案已在河南省新建变电站和老变电站直流电源改造中应用,运行结果证明所提方案是可行的。
How to prevent DC bus loss of power and ensure the security of power supply while switching the operation mode during the substation DC system periodic test is an important problem on site. This paper introduces the abnormity of the DC bus loss of power in a power substation, analyses and confers the reason of the abnormity, and gives the solutions. The solutions have been applied in the new substation project and the old substation DC system reconstruction project in Henan power grid. The running results indicate that the solutions are feasible.
