Leakage and loss metering control method based on pipe network leakage amount, apparent loss amount, and supply and sales difference water amount of water supply system

Abstract

The invention discloses a metering control method based on three quantities of a water supply system. The metering control method is to firstly use the flow rate of the water supply system to collect data, collect the required basic data, and use the collected data to calculate the amount of pipe network leakage, Calculation of apparent loss and production-sales difference water volume, measurement analysis and control of pipe network leakage, apparent loss and production-sales difference water volume. It has the following advantages: Simplify the complicated quantitative control of leakage loss to the measurement and analysis of the three quantities of pipe network leakage, apparent loss, and production-sales difference in the water supply system only through the flow rate, and realize the control of pipe network leakage, Early warning of apparent loss to reduce production-sales gap.

Description

technical field [0001] The invention relates to a method for controlling the leakage of a water supply system, in particular to a method for measuring and controlling the leakage of three quantities based on the water supply system including the leakage amount of the pipe network, the apparent loss amount and the difference between production and sales. Background technique [0002] According to a recent statistics from the Ministry of Construction of my country for 408 cities, the average leakage rate of the current pipe network is 21.5%. At present, the high leakage rate of the pipeline network is mainly due to the lack of perfect system control in the traditional leakage control methods. The leakage control method usually uses the listening method to judge the leakage point of the pipeline network, which is a single method. [0003] The current leakage control operation mode is widely implemented through the technology of DMA (District Metering Area) independent metering ...

AI Technical Summary

Problems solved by technology

[0006] When calculating the amount of water leakage in the pipe network, the formula cannot accurately identify the smaller amount of water leakage; the leak detection operation area is large, time-consuming, laborious, and labor-intensive; the leakage warning lags behind; the apparent water loss cannot be determined; in order to obtain the leakage loss of the pipe network All kinds of data need to be tediously collected and input on various calculation parameters such as flow rate, pressure signal, pipe network attributes, etc. If any of the data drifts and errors, there will be calculation results that deviate from reality, leading to wrong judgments; moreover The equipment required to establish the use of DMA to calculate the water loss of the pipe network is expensive, and the installation, commissioning and operation management are very cumbersome
