摘要
Abstract
Step load curve and traditional calculation method of battery capacity in DC power supply system of plant/substation are expounded. Then coefficient relation curves between discharge time and required battery capacity of four arbitrarily selected storage batteries are obtained by using battery capacity conversion coefficient table. Characteristics of above curves are analyzed. Based on difference of battery capacity between initial discharge stage and follow-up discharge stage, the battery capacity is divided into basic capacity and consumption capacity. Mutual interaction and changing trend of the basic capacity and the consumption capacity in discharge process of the battery are studied. On this basis, for typical accident discharge curves, a new algorithm for calculating the battery capacity of a power plant or a substation is presented. Calculation process of the new algorithm and advantages to traditional algorithm are discussed. Finally, the method dealing with impact load in the new algorithm is studied. Battery capacities of five typical discharge curves are calculated with traditional current conversion algorithm and the new algorithm respectively, and rationality and effectiveness of the new algorithm are verified.关键词
