Discharge Prediction of Photovoltaic Pumping System and Experimental Research
摘要
Abstract
Basedontheanalysisandexperimentaldata,eachpartofthephotovoltaicpumpingsystemincludingphotovoltaicar-ray,controller,motor,centrifugal pump and pipeline was modeled by means of simple equations and data fitting.According to the linear relationship between irradiation and output power,the controller and motor efficiency at different input power were obtained through experiment.The characters of a centrifugal pump between flow,head and efficiency were obtained through test.The pump performance in all conditions was obtained through the affinity method.The prevision method for discharge of the pumping system was established by these equations and the result was compared with experimental result at different irradiation levels.The result shows that the simulation result is close to the real.The precision was in 5%when the irradiation was more than 500 W/m2 .Com-parisons of the discharge throughout the day between predicted data and experimental ones were made in the two days of highest and lowest irradiation during a year.The result indicates that the precision were less than 3%.It shows that the model can predict total water throughout the day accurately.It provides a reference for predicting the performance of photovoltaic pumping system and system configuration.关键词
