Abstract: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.
