Solar powered water pumping system employing switched reluctance motor drive

Abstract

This paper deals with the simple design method and performance investigation of a solar photovoltaic (SPV) array fed water pumping system employing a switched reluctance motor (SRM) drive coupled to a centrifugal water pump. SRM possessing a number of advantages over the dc and ac motors such as high torque density, low inertia, quick response, low losses because of the absence of permanent magnet or winding on the rotor, wide speed range capability, and simple control, suits for the SPV powered water pumping system. A DC-DC Cuk converter which facilitates the continuous and smooth input/output current and boundless region for maximum power point tracking (MPPT) operation is used as an intermediate DC-DC converter between the SPV array and the mid-point converter, in order to operate the SPV array at its optimum power point. The proposed system, subjected to the dynamically changing atmospheric condition is designed; modeled and simulated using MATLAB/Simulink and the simulation results of SRM are represented to demonstrate its suitability and performance.

Development of low‐cost PV array‐fed SRM drive‐based water pumping system utilising CSC converter

“…Only few attempts have been reported in the literatures [18][19][20][21] which describe the operation of PV-powered water pumps utilising SRM as a drive. A two-switch topology with a battery, voltage regulator which regulates and limits the charging and discharging process of the battery is proposed in [19] and shown in Fig.…”

Solar Array Fed Synchronous Reluctance Motor Driven Water Pump: An Improved Performance Under Partial Shading Conditions

“…Considerable literature publications have been investigated the solar pumping systems when brushless DC motors (BDCMs), induction motors (IMs), PM synchronous motors (PMSMs) and switched reluctance motors (SRMs) are employed [12], [13], [14], [15], [27]. The solar pumping systems using BDCMs have been extremely investigated in the literature.…”

Self‐governing single‐stage photovoltaic water pumping system with voltage balancing control for a four‐phase SRM drive

“…Given various advantages of SRM drive in SPWPS, many publications have examined the performance of different configurations of SRM drive for water pumping application [8][9][10] and [13][14][15][16]. All these configurations can be classified into two major categories.…”

“…The inverters involved to excite the SRM windings have low-energy feedback with higher components in this system [8][9][10]13]. Although, the system discussed in [14,15] has used a fundamental switching technique to commutate the SRM windings and have low sensor requirement. The presence of the DC-DC converter and the utilisation of conventional MPPT technique results in a lowefficiency system with slow dynamic response and high-rated DClink capacitors.…”
