摘　　要：针对现有的煤矿排水系统避峰填谷控制方案存在水泵启停频繁等问题,提出通过细分水位及启泵数量、增加低谷调整时段及最后调整时段等方法对现有方案进行优化改进的方案,给出了避峰填谷的原则及改进方法的具体实现,并对原方案及改进方案的控制效果进行了对比分析。测试结果表明,改进后的避峰填谷控制方案在高峰时段的泵时缩短为改进前的33%,尖峰时段的泵时缩短为改进前的42%,提高了水泵运行效率。For problem that pumps start and stop frequently in existing control scheme of peak load shafting of coal mine drainage system,the paper proposed an improved scheme by adding water levels,raising number of activated pumps,increasing a trough adjustment period and the last adjustment period.It introduced principles of peak load shafting and implementation of the improved scheme,compared and analyzed control effects of the original scheme and the improved scheme.The testing results show that pumping time reduces to 33% in peak period and 42% in rush period of the improved scheme,which improves pump efficiency.
