Control Of Pv Water Pumping System Water Levels

Solar pumps are used on small farms, private homes, orchards, etc. It is most economical to power the pump directly from the PV array, store water in a tank, and then distribute it. The test bench installed at the research unit of Ghardaia URAER is used to test and characterize different PV pumping systems and the results of this characterization are presented in this paper. A novel method of water consumption management through a Photovoltaic water pumping system, installed on real well has been studied. The method consists of controlling the water usage via the storage tank level and the consumption. The main purpose is to adapt the variation of the water consumption by an end user. The designed control system is based on the control of water supply from a submersible solar powered pump according to the variation of water demand. Taking into account the permanent solar energy supply and the availability of the water. The control design is satisfied by a Fuzzy Logic Controller (FLC), that senses the varying level of water in the storage tank and the end user requirement, so that the storage tank or a reserve tank is filled up, for its satisfactory performance. The Through different environmental condition recorded, the proposed system design has been simulated and validated by Matlab toolbox. The obtained results averred a very high controlling effectiveness of both the water management and the PV pumping system operation
