DSPACE implementation and experimentation of Power Field Oriented Control for motor-pump fed by intermittent renewable sources

Abstract

This paper presents the experimental results of an original control strategy for motor-pump implemented on a dSPACE controller board. The Power Field Oriented Control strategy developed in this paper is used to drive a motor-pump fed by intermittent renewable sources. This system is dedicated to autonomous applications for pumping or water desalination for remote areas without access to hydraulic and electric networks. This control strategy allows controlling the DC bus voltage without using batteries in the system. The DC voltage control is achieved through the control of the inverter used for the motorpump. Experimental results for variable power source are presented and confirm the effectiveness of the proposed control strategy.

Dynamic Energy Management for Real Time Control of Battery Less PV-Wind Powered Desalination Unit

“…The numerical expression of the PI regulator is given by (4) and represented by Figure 6. In validation phase, the renewable source was emulated using a programmable power supply that can generate a variable power profile up to 4kW [13] (Figure 7). Experimental tests were carried out through a basic Energy Management System (EMS) that determines the reference power to be applied with PFOC control [14].…”
