Automatic Follow The Tracks Of Sun Of Solar Pump Design And Performance Prediction

Along with the solar cell material and photovoltaic technology development, the greatsocial and economic benefit of photovoltaic pump system, have be widely used in recentyears. It is a convenient installation, don’t need carry the battery, have no limit of the powersupply and the strongly mobility and other characteristics, has been widely used in human andlivestock drinking water mobile irrigation, or other fields. Photovoltaic water pump for ourcountry’s Midwest region of electricity has a great significance. Along with the rise in theprice of oil and photovoltaic cells down, photovoltaic system capacity has significantlyincreased, so the solar energy use is becoming more and more economic. And pv array of theefficiency and stability also had the very big enhancement. The right system design and theright match of solar energy output between load the phalanx, can achieve the whole deviceefficiency improved. In this paper on photovoltaic water pump has been designed, with goodmatch to the characteristics of solar panels. Sign in the traditional photovoltaic water pump isusually be seted direction type is decorated, the solar energy utilization of lower, throughextensive reading of documents and material, this paper conventional solar energy waterpump to the innovative design improvement.Main contents are as follows:1．Photovoltaic battery power output belong to nonlinear, there is the problem of the highpower output tracking. This paper used the maximum power point tracking method,photovoltaic cells work in maximum output power point, get high power output. Andaccording to the mechanical pump pv characteristics of its choose the right frequencyconversion control mode.2. According to conventional solar photovoltaic board fixed direction to decorate theshortcomings of low efficiency of solar energy, this article innovative increased solarphotovoltaic board of automatic tracking system light, and the principle analysis, andchoose the suitable way to track;3. According to the characteristics of agricultural irrigation pump, selected self-suctionpump for the system, through the design parameter design out of the meetingperformance requirements self-priming pumps, and calculated the self-study time andheight. Through the FLUENT software to pump for a whole flow field imulation, andthe simulation data was be analyzed, the self-suction pump hydraulic performancecurves were be got, and the curves meet the design requirements.
