Abstract
This paper focuses on an original control experimentally implemented for water pumping system fed by hybrid (PV-Wind) generator without battery storage. The water pumping system uses centrifugal pumps driven by variable speed three phase Induction Motors (IM) controlled by a new Power Field Oriented Control (PFOC). As we have eliminated the battery storage, the system operating point is imposed by the intermittent renewable source, given the hydraulic load characteristic; the basic idea is to use both degrees of freedom offered by the inverter in order to control the DC bus voltage and the rotor flux of the induction machine. Experimental investigations show the satisfying performance of the system even with variable power source.
