高海拔变电站蓄电池及UPS容量选择及修正

Capacity Selection and Correction of Storage Battery and UPS in High Altitude Substation

摘要:

高海拔地区环境温度低、空气密度及气压低，在进行变电站站用蓄电池及UPS容量选择时应进行必要的修正，以提高蓄电池及UPS气候适应性。结合阿里与藏中联网工程的某500kV变电站项目，对高海拔变电站蓄电池及UPS容量选择进行了探讨分析，希望能为类似工程提供参考。

Abstract:

Because the ambient temperature, air density and atmospheric pressure in high altitude area is very low, a necessary correction should be done when selecting the capacity of storage battery and UPS for substation?in high altitude area in order to improve the climate adaptability of storage battery and uninterruptible power supply (UPS), The capacity selection of storage battery and UPS in a 500 kV substation of Ngari power grid and central Tibet power grid interconnection project are discussed and analyzed in the hope of providing a reference for similar projects.
