UPS在500千伏变电站的应用

Application of UPS in 500KV Transformer Substation

本文介绍了UPS在电力系统500千伏枢纽变电站的应用,分别从输入电压和频率、过载能力、蓄电池的选择、系统切换时间等方面介绍了变电站UPS的选型,针对云田变电站使用的带有旁路及静电开关的在线式UPS,可能引起的故障起因及运行操作中的对策予以分析和探讨。

The application of UPS in 500kV hinge transformer substation is introduced in this article. The selection of such UPS used in transformer substation, based on input voltage, operating frequency, overload capability, battery selection and switching time, is also presented. And the cause of failure and operating strategy for the on-line UPS with bypass and static switch are also analyzed and discussed.
