Abstract

The research suggests a mathematical model which represents the performance of photovoltaic water pumping system. The suggested system is considered one of the best used systems for producing clean electric power that is necessary for operating water pumps. The proposed system has been extrapolated by using main mathematical equations which expressing the performance of pumping system's components which are represented the photovoltaic cells and the group of the water motor-pump. A Mat Lab/Simulink used to construct a same numerical model. The extracted results are the same from both model and these results approved their validity. The photovoltaic water pumping system includes permanent magnet DC motor (PMDM) that is fed directly by the photovoltaic cells. And the water pump used in this purposed system is (centrifugal) type. The mathematical models can be used generally for any place which their solar characteristic is known to determine the amount of water that can be pumped to the used pumping system. And the system was applied at a village near Cairo. The suggested model can be used in determining the components of the suggested system and determining the amount of water and the size of tank that will be used for this purpose.
