ENERGY SAVING BY OPTIMAL-CONTROL OF WATER-SUPPLY

The authors describe a collaborative project concerned with the introduction of an optimal on-line control for the water supply network. Attention is concentrated on the data gathering, modeling and simulation aspects of the project. A generalized mathematical model described was developed which is suitable for steady state analysis, dynamic simulation and real time control techniques for a water distribution system. Basic data for the proposed model include a physical description of water distribution system including pipe length, diameters, friction coefficients, pumping stations, storage tanks and reservoirs, loop definitions as well as the variables affecting network operation.
