Modelling and Design Methodology of an Improved Performance Photovoltaic Pumping System Employing Ferrite Magnet Synchronous Reluctance Motors

Abstract

This paper proposes a novel photovoltaic water pumping system (PVWPS) with an improved performance and cost. This system doesn’t contain a DC-DC converter, batteries nor rare-earth motors. Removing the aforementioned components will reduce the whole cost and increase the reliability of the system. For enhancing the performance of the PVWPS, a ferrite magnet synchronous reluctance motor (FMSynRM) is employed. Besides, the motor inverter is utilized to drive the motor properly and to extract the maximum available power of the PV system. This is performed using a suggested control strategy that controls the motor inverter. Furthermore, to show the effectiveness of the proposed PVWPS, the performance of the proposed system is benchmarked with a PVWPS that is employing a pure SynRM. Moreover, the complete mathematical model of the system components and the control is reported. It is proved that the flow rate employing the proposed system is increased by about 29.5% at a low irradiation level (0.25 kW/m2) and 15% at a high irradiation level (1 kW/m2) compared to the conventional solar system using a pure synchronous reluctance motor (SynRM). An experimental laboratory test bench is built to validate the theoretical results presented in this research work. Good agreement between the theoretical and the experimental results is proved.

Perovskite Solar Cells and Thermoelectric Generator Hybrid Array Feeding a Synchronous Reluctance Motor for an Efficient Water Pumping System

“…To avoid the inductance variation with time, the dq-axis reference frame is commonly used to model AC machines. The inductances along the dq-axis of SynRM varies with analogy current parts along the dq-axis [9,10,29,30]. The SynRM magnetic saturation results from the variation of the motor inductances It was previously proven that the SynRM model should have the effect of magnetic saturation on the motor inductances for the SynRM performance prediction in the right way [21].…”

“…SynRM modeling is performed based on the dq-axis rotor reference frame. From previous studies [44,47], Equation ( 4) represents the SynRM model [47]:…”

“…Moreover, the second reference signal (d-axis current single (i d *)) is extracted based on the FEM in LUT, which correlates the reference current signal (i d *) and the motor torque. The trial-and-error principle was used for determining the PI controller's parameters [44,47].…”

Dynamic Modes of Synchronous Electric Drive with Centrifugal Hydraulic Load of Pump Station

“…Despite the substantial benefits offered by the use of synchronous motors (SM) in comparison with induction motors for driving centrifugal pumps (CP) [2], [3], these are the synchronous sets of high-powered PS that, we believe, have not received sufficient research attention. The following major areas of modern studies of this problem can be distinguished: modelling of dynamic modes of controlled synchronous electric drives of low-and mediumpower fluid pumping systems with utterly simplified representation of the hydraulic subsystem (as in [4]- [8]), modelling of steady-state modes ( [3], [9]) and obtaining of generalized energy indicators and technical-and-economic indicators ( [10]). Therefore, the study of high-powered fluid pumping systems with the synchronous electric drive is of topical importance.…”
