Experimental characterization and energy analysis for water pumping system fed by intermittent source

This paper studies an original energy management system with control strategy dedicated to an autonomous pumping system fed by intermittent renewable source without battery storage. Power Field Oriented Power is used to control the DC voltage of the source and the rotor flux of the motor-pump. As the motor pump is power controlled, the system operating point is imposed by the source given the hydraulic load characteristic. The basic idea is to study theoretically and experimentally the system behavior under variable given power and many hydraulic loads. Finally power management strategy is deduced allowing satisfying performances of the system.
