摘要(Abstract)：

阐述了厂/站直流电源系统中阶梯负荷曲线及传统蓄电池容量计算方法,利用蓄电池容量换算系数表,得到任取的4种蓄电池的放电时间和所需蓄电池容量的系数关系曲线,分析了上述曲线的特点。基于放电初始阶段和后续阶段所需蓄电池容量的差异,提出将蓄电池容量分为基础容量和消耗容量,并研究了基础容量和消耗容量在蓄电池放电过程中的相互作用和变化趋势。在此基础上,针对典型事故放电曲线,提出了计算发电厂和变电站蓄电池容量的新算法,详细论述了新算法的计算过程及相比于传统算法的优势,最后研究了随机冲击负荷在新算法中的处理方式。采用传统电流换算法和新算法分别对5个典型放电曲线所需的蓄电池容量进行了计算,论证了新算法的合理性和有效性。

关键词(KeyWords)： 蓄电池;容量计算;容量换算法;电流换算法;阶梯负荷曲线
