摘　　要：参考并联变频水泵特性模型,运用极值分析法提出了并联变频水泵台数在线优化配置方法,通过连续监测并联水泵总流量与扬程在线决策当前水力工况下的最佳水泵运行台数.采用变压差设定值控制策略的变流量空调系统中并联变频水泵的控制仿真表明,较单泵运行与双泵运行策略,该方法可分别获得18.8%与4.1%的水泵节电量.With reference to performance model of parallel variable speed pumps,an optimal allocation scheme,which can make online decision on optimal pump operation number according to continuous monitoring of total water flow and pump head,was presented based on theoretical derivation using extreme value analysis method.Simulation work on variable water system with variable differential pressure setpoint control strategy was studied,and results showed that the online optimal allocation scheme could achieve 18.8% and 4.1% pump power saving compared with single pump operation scheme and twin pump operation scheme,respectively.
