摘　　要：目前供水企业的产销差率和漏损率一般都以年为单位进行统计,这种计算方法有明显的滞后性,使得供水企业无法第一时间掌握产销差率实际情况。基于此,提出了实时产销差率的概念,并给出了基于DMA分区计量的实时产销差率估算方法。实际案例分析结果表明,在不复杂的DMA分区背景下,基于DMA分区计量的实时产销差率可以直观地体现DMA分区管理质量,帮助供水企业了解该区域控漏效果,也提高了对漏水点的检出速度,节约了大量的水资源。At present,non-revenue water(NRW)rate and leakage rate of water supply enterprises are generally calculated by year.However,this estimation method has an obvious lagging problem,which makes the water supply enterprises unable to grasp the actual situation of NRW rate at the first time.Therefore,the concept of real-time NRW rate was proposed,and a real-time NRW rate estimation method based on DMA partition measurement was established.The actual case analysis results showed that the real-time NRW rate based on DMA partition measurement could directly reflect the quality of DMA partition management under the background of uncomplicated DMA partition.In addition,it could help water supply enterprises to understand the leakage control performance in this area,improve the detection speed of leakage points,and save a lot of water resources.
