新型分布式直流电源在110kV变电站的应用研究

A new Distributed DC Power Supply Application in 110kV Substation

本文介绍一种采用并联智能电池组件的新型分布式直流电源,与传统直流电源相比,提高了蓄电池使用寿命、减少了维护工作量和直流系统绝缘故障点。针对110k V变电站的直流负荷情况、分布特点,对应用方案进行分析研究。将两种直流电源方案从技术、经济两个方面进行论证分析,为用户提供更多的方案选择。

This paper introduces a new distributed DC power supply parallel intelligent battery assembly, it compared with the traditional DC power supply to improve the service life of the battery, reduce the maintenance and DC system insulation fault point. In this paper, according to the 110kV substation DC load and the characteristics of distribution.Two kinds of DC power supply scheme from two aspects of technology, economy analysis, provide more choices for the user.
