摘要
根据工程实际数据,使用HOXIE算法和电压控制两种方法计算蓄电池容量,寻求两种方法的异同和联系。分析中发现电压控制法对于较复杂的蓄电池放电过程的计算存在不准确的地方,经过探讨对电压控制法提出了改进方案,改进后的电压控制法在复杂放电过程中也可以得到精确的计算结果。同时使用现有220kV变电站参数,为220kV变电站直流系统研究提供了较实际的详细数据。
On the basis of practical data in 220 kV substation, HOXIE method and voltage control method are used in storage battery capacity calculation. Similarities and differences between two methods are found. It is also found that there is inaccuracy in complex storage battery discharge calculation when using voltage control method. Furthermore this paper proposes improvement scheme for voltage control method, which makes voltage control method accurate in complex discharge. At the same time the present 220 kV substation parrmeter provides practical data for DC system research.
