电力系统变负荷条件下铅酸蓄电池选型计算K系数特性曲线的选定

Determination of K-factor curves while sizing lead-acid batteries for variable load of electric power application

铅酸蓄电池的K系数值或K系数曲线是电力系统电池容量选定的必需的基础数据。而K系数与阀控式电池的所采用的技术路线 (胶体或AGM)、电解液浓度的差别、电池的容量、单体式或整体式诸多因素有关 ,本文针对以上因素进行了比较。通过综合比较可以看出 ,采用过于简化的K系数 (或K系数曲线 )很难保证电池的选型准确适当。

K values or K characteristic curves of lead acid battery are basic figures to size the batteries for electric power system application.The K values of VRLA are related to the technical ways(Gel or AGM),the density of electrolyte,cell capacity,and the structure of cell or monoblocks.The factors mentioned above were compared in this paper.By this comparison it is concluded that too simplified K values(or K curves)can not exactly size the battery.
