Comparative Study of a Wind Turbines Hybrid System Based on a Permanent Magnet Synchronous Generator Used to Power a Water Pumping System
摘要
This paper describes and investigates the performance of a new hybrid wind turbine system for water pumping. The proposed system uses several small wind turbines, instead of one turbine, to generate the electrical energy needed to power a 1.5 kW pump. Firstly, a techno-economic analysis of the systems showed that there are economic and technical advantages between one or more wind turbines to ensure the energy autonomy of a pumping system. Subsequently, the characteristics of the hybrid system were determined, and it is shown that the system can be optimized. A MPPT controller based on Perturb & Observe was tested and applied on the studied system to determine the appropriate MPPT algorithm. Simulation results verify the effectiveness of the proposed system and control algorithm.
