Characteristic analysis of water consumption data in metering zones of water distribution systems
Abstract: Monitoring data reflect the operation state of water distribution systems.With the development of information and communication technology,monitoring data can be transmitted in near real time.Under this condition,it becomes possible to detect abnormal conditions in near real time through the rapid analysis and mining of the monitoring data in metering zones.This paper uses statistical analysis method to analyze the data characteristics of water consumption data in metering zones from the perspective of time series.The results show that the fluctuation of water consumption data can be divided into three types:regular fluctuation,uncertainty fluctuation and error data.This lays a foundation for developing data-driven anomaly detection methods.
