摘要

本文比较了分别由直流电机(DCM)和感应电机(IM)驱动的两种光伏水泵系统，通过耦合离心泵的DC/DC降压-升压变换器驱动。两个系统通过P&O MPPT算法进行优化，该算法旨在最大化整体效率，从而最大化耦合离心泵的驱动速度和排水量。在MATLAB/SIMULINK中对光伏水泵系统的各个组成部分进行了研究和分析。然后比较两种系统的效率和每天抽水的数量。该研究得出结论，与其他系统相比，im驱动的光伏系统产生了非常有利的效果，并且需要更少的维护。本文比较了分别由直流电机(DCM)和感应电机(IM)驱动的两种光伏水泵系统，通过耦合离心泵的DC/DC降压-升压变换器驱动。两个系统通过P&O MPPT算法进行优化，该算法旨在最大化整体效率，从而最大化耦合离心泵的驱动速度和排水量。在MATLAB/SIMULINK中对光伏水泵系统的各个组成部分进行了研究和分析。然后比较两种系统的效率和每天抽水的数量。该研究得出结论，与其他系统相比，im驱动的光伏系统产生了非常有利的效果，并且需要更少的维护。

Comparative study on photovoltaic water pumping systems driven by direct current motor (DCM) and induction motor (IM) optimized with P&O control

This paper presents a comparison between two photovoltaic water pumping system driven by a separately excited DC motor (DCM) and an induction motor (IM), via a DC/DC buck-boost converter coupled to a centrifugal pump. The two systems are optimised by a P&O MPPT algorithm, which aims to the maximisation of the global efficiency, will lead consequently to maximize the drive speed and the water discharge rate of the coupled centrifugal pump. Each component of the PV water pumping system is studied and analyzed in MATLAB/SIMULINK. The two systems are then compared in terms of efficiency and quantity of water pumped per day. The study concludes that the IM-driven PV system yields highly favorable results and requires less maintenance compared with other systems.This paper presents a comparison between two photovoltaic water pumping system driven by a separately excited DC motor (DCM) and an induction motor (IM), via a DC/DC buck-boost converter coupled to a centrifugal pump.
