Abstract
Over the year, Egypt was one of the famous countries with their crops, that produced enough food to fill the local market. Currently, with the high population issue that creats a huge demand on food, Egypt is importing more than 50% of its needs of food. Thus, Egypt has high needs to widen its agriculture lands and fill the crops shortage. Egypt has good available underground water, solar resources and lands. On the other side, Egypt has shortage in the fossil fuel. Therefore, Egypt has high potentional to fill its increasing needs by using solar water pumping systems. Solar water pumping systems are considered as the optimum solution for supplying water using clean and cost effective solution. The solar water pumping system consists of Photovoltaic (PV) modules that convert the sun light to electrical power. A controller is the main item that functions to get the maximum power from the modules. It ensures smooth and full control of the motor that is coupled to water pump through mechanical shaft. This thesis studies in details the design, modeling, sizing and performance evaluation of the solar water pumping system. The modeling controller consists of two stages: first stage is DCDC converter with maximum power point tracking (MPPT) to extract maximum power, and second stage is DC-AC converter with implemented speed sensorless vector control of the three phase induction motor. One of MPPT algorithms is applied and simulated in Matlab Simulink environment. The system is functionality are verified. Designing of solar water pumping system methodologies also is investigated in details. Technical and economical parameters are considered in the design procedures. A full monitoring of system is also presented to measure and evaluate the performance. Economical study of the solar water pumping system is also presented. An expermential case study of 45 kWp solar water pumping system in El-Wahat, Egypt is discussed.
