Modelling of PV Powered Stand-Alone Water Pumping System Using PMSM Drive
The aim of this project is to design and construct a solar charge controller, using mostly discrete components. The charge controller varies its output to a step of 12V; for a battery of 200Ah rating. The design consists of four stages which include current booster, battery level indicator, battery charge controller and power supply unit. The designed system is very functional, durable, economical, and realizable using locally sourced and affordable components. This work is a prototype of a commercial solar charge controller with protection systems that will prevent damages to the battery associated with unregulated charging and discharging mechanisms.This paper is to reduce the human intervention for farmers and use solar energy for irrigation purpose. The entire system controlled by the PIC microcontroller.
The solar PV panels have proven through a period of time that they are unfailing to produce adequate electricity directly from solar radiation. The demand for water in any irrigation system varies throughout the complete year in any particular area. This paper proposes the use of solar power for irrigation purposes. Solar powered water pumping systems can be the most perfect and suitable solution for rural locations which are grid isolated in poor countries where the amount of solar radiation are very high. Solar powered water pumping systems (SPPS) can be used to supply to basic needs of the community like providing drinking water, water for irrigation etc. without the need for any kind of fuel or wide-ranging maintenance.
