摘　　要：目前二次供水设备的能耗监控需要用到设备流量数据。但是因为成本原因,在大量设备现场没有安装流量计,造成无法进行二次供水设备能耗状态评价。为解决该问题,提出了基于二次供水设备用能强度比数据的统计分布特征进行能耗状态评价,并进一步通过双样本t检验分布来追踪设备间用能比例的变化程度,进行设备能耗异常侦测的方法,基于该方法实现的二次供水设备能耗状态监控系统在实践中体现出了较大的实用价值。There must be flow data to evaluate the energy consumption status of secondary water supply equipment.But flowmeter is seldom installed in secondary water supply site because of cost,which result in failing to evaluate the energy consumption status.In order to solve the problem,a new method is proposed.The method evaluate the energy consumption status based on statistical distribution characteristics of energy consumption intensity ratio,and use two sample T-test distribution to track the variation tendency of energy consumption ratio between equipments to detect the abnormal energy consumption.An energy consumption monitoring system to secondary water supply equipment based on the proposed method has shown preferable practical value.
