Analysis of pump interaction and efficiency in control of water supply

Abstract
The paper analyses water distribution system pumping elements in order to derive models suitable for incorpor ation in network simulation and optimisation schemes. This includes derivation of an independent control variable to give simulated pump operation on a continuous or discrete basis allowing for head dependent flows. Derivation of the necessary conditions for operation at maximum efficiency are also presented. Typical pumping operations are investigated in order to develop and justify cost models for various optimisation techniques in terms of electricity charges.
