摘　　要：目前对阀控式铅酸蓄电池建模的研究很少,而且都是针对一种放电倍率,而工业上往往要求蓄电池能工作在不同放电电流下。基于红河变电站实验环境,利用变电站直流屏使用丰日2 V 200 Ah蓄电池GFM-200和新威充放电仪器,并使用Matlab仿真软件对蓄电池建模,实现了一个等效电路模型,满足了不同放电电流仿真的要求。仿真数据与实验数据相比较,结果显示二者有较好的吻合度,可为蓄电池性能研究和正确使用提供参考。Valve regulated lead acid（VRLA） battery was applied extensively in substation DC systems. Nowadays the battery Matlab modeling was mainly for lithium cell. But the Matlab modeling of VRLA battery had rarely literature. At the same time, all reference for modeling of VRLA Battery was under one discharge ratio. However, VRLA battery was often required work in different currents. With the experimental environment in Honghe substation, FENGRI 2 V 200 Ah battery （GFM-200） and XINWEI BTS were used as the VRLA battery in DC systems of substation. It aimed at using it to charge and discharge in different current. And the experimental results were basically consistent with simulation results. Besides, it could provide reference for performance study and the correct use of VRLA battery.
