Water Distribution Operation Systems Based on Smart Meter and Sensor Network

In this study, smart meter, water quality measuring sensors, and major operation skills are developed on the basis of real-time operation and management environment. Smart meter is designed by improvement of conventional water meter to secure accuracy and communication function. Finally, in order to obtain the information for the effective operation and management of water distribution systems, forecasting algorithm of abnormality water use is developed using Kalman filter and principal component analysis. Developed model is then implemented for real on-line measurement of the flow at the test district metered area (DMA) in southern city of Korea.
