摘　　要：针对以往关于变电站蓄电池充放电过程的研究较为薄弱的现状,详细分析了蓄电池的充放电特性。采用电流换算法检测蓄电池的容量,根据多次的实验结果绘制充放电曲线,建立蓄电池的充电和放电数学模型,量化了蓄电池的充放电过程。以实际蓄电池为例,分析变电站蓄电池的充放电过程特性,验证所构建的蓄电池充放电模型的正确性和合理性,为进一步研究变电站直流系统的特性提供一定的理论基础。For those research about charging/discharging process of substation battery were weak, the charging/discharging features of battery were analyzed in detail. The algorithm of current translated was used to measure the battery capacity, and the curve of charging/discharging of battery was figured according to outcome of repeated experiment. The math model of charging/discharging of battery was built. The process for charging/discharging process of substation battery was quantified. The real battery was used to make simulation and analysis,and the rightness and reasonable of the battery was proved by the model of charging/discharging of battery. Some theory base for the research about the direct-current system of substation was provided.
