摘要
城市轨道交通变电所操作电源为一级负荷中的特别重要负荷,变电所蓄电池负责为其提供电源。针对目前城市轨道交通变电所蓄电池容量选择仅凭经验,缺少详细调查分析以及针对性计算的现状,文章通过对城市轨道交通变电所内的直流负荷进行详细调查,基于IEEE Std 485-2010和DL/T 5044-2014标准分别对典型变电所蓄电池容量进行计算,并对计算结果进行对比分析,最后提出常规变电所蓄电池容量的配置建议。
The substation’s operational power supply for urban rail transit is particularly important,and the substation battery is responsible for providing power for it.In view of the current situation that the battery capacity selection of urban rail transit substations is based on experience;detailed investigation,analysis and targeted calculations are lacking.This paper investigates the DC load in rail transit substation in detail,and calculates the battery’s capacity of typical substation based on the IEEE Std 485-2010 and DL/T 5044-2014.After comparing and analyzing the calculation results,the recommended battery capacity for an urban rail transit typical substation is given.
