Abstract
This paper presents the modeling and simulation of electrical water pumping system using solar energy. Now-a-days PV array is increasingly employed for water pumping system. In this paper, the developed boost converter steps up the voltage produced by the PV array to a value which is suitable to run a single-phase induction motor. The inverter converts DC to AC is controlled by using sinusoidal pulse width modulation (SPWM) technique. By using a LC filter the harmonics are eliminated and pure sine wave is obtained which can be directly used to drive a single-phase induction motor and pump system. The Experimental investigation presented gives the utility of such a drive system. A design of directly coupled solar water pumping system powered from photovoltaic panels, DC to DC Boost converter, full bridge sinusoidal pulse width modulation (SPWM) inverter, LC filter, induction motor and centrifugal pump is presented. The PID feedback controller is used to control the voltage. The model was implemented using MATLABI Simulink with SPWM controlled inverter model.
本文介绍了太阳能电动抽水系统的建模与仿真。目前,光伏阵列越来越多地应用于抽水系统。在本文中,开发的升压变换器将光伏阵列产生的电压升压到适合单相感应电动机运行的值。逆变器采用正弦脉宽调制(SPWM)技术控制直流转交流。采用LC滤波器消除谐波,得到纯净的正弦波,可直接用于驱动单相感应电机和泵系统。实验研究给出了这种驱动系统的实用性。提出了一种由光伏板、DC - DC Boost变换器、全桥正弦脉宽调制(SPWM)逆变器、LC滤波器、感应电机和离心泵供电的直接耦合太阳能水泵系统的设计方案。采用PID反馈控制器对电压进行控制。该模型采用matlab Simulink实现,采用SPWM控制的逆变器模型。
