摘要

光伏(PV)抽水系统在毛里塔尼亚广泛应用,以确保农村地区人口的供水需求。该系统由光伏发电机、DC/DC变换器、DC/AC逆变器、无刷直流电机和离心泵组成。本文研究了在Matlab/ Simulink环境下,考虑气候参数(太阳辐照度、环境温度)和总压头(HMT)对泵送流量的影响,对光伏泵送系统的性能进行了仿真研究。此外,还计算了各气候参数的电能和流量。本文提出了两种用于光伏应用的电机泵数学模型,以促进光伏泵泵尺寸的研究。这些模型直接将工作电流与电压联系起来,并将电力与泵的流量与总扬程联系起来。

Performance Optimization and Modelization of a Photovoltaic Pumping System
The photovoltaic (PV) pumping system is a widely used application in Mauritania to ensure the water supply in rural area for populations needs. The system is composed of a PV generator, a DC/DC converter, a DC/AC inverter, a BLDC motor and a centrifugal pump. Study in this article we study with simulation in Matlab/ Simulink environment the performances of the PV pumping system taking into account the climate parameters (solar irradiance, and ambient temperature), and the effect of the total manometric head (HMT) on the pumped flow rate. In addition it also counted the electrical energy and flow rate of the each climatic parameter. Two mathematical motor –pump models for PV application, were proposed in this article to contribute in the studies of PV pumping sizing. These models link directly the operating current to the voltage and electrical power to the flow rate of the pump versus total head.
