Timer Switching Control Applied to Municipal Water Pumping System

Abstract In this paper, the timer control and inverter of pumping system are modelled simulated. The effects evaporation, rainfall seepage considered to make model more practical. proposed VFD used motor pump, which saves a lot cost. MATLAB/SCIP optimization software was implement developed model. Simulation assess performance electrical switching system. Two scenarios were simulate model: first, applied fixed speed water second, integrated with power pump. simulated results compared in order calculate economic benefit. comparison baseline case, where load demand is met using for given day operation demonstrate that employing suggested pump can save 706 ZAR operating cost each day.
