Optimal Design of Fused Chopper based Standalone Hybrid Wind Solar System


Objective: The target of this paper is to implement an economical chopper and electrical converter for the hybrid windsolar system. Method: a replacement topology of a mix of CUK and SEPIC convertor is used rather than a private DC/DC convertor. The motor load is provided by victimization the two diodes that connects each wind and solar energy singly or along depending on accessibility. With the improved management in DC/DC convertor and within the electrical converter that associated with the auxiliary circuit in accumulation by the closed-loop system PI controller a more robust control is achieved. Findings: The fused chopper replaced the separate solar and wind choppers and rather than typical electrical converter the novel pulse width modulated electrical converter used supplied with a correct pulse width modulation (PWM) control using 3 equal reference signals. The closed-loop system management is achieved with the digital PI controller and MPPT draws the maximum power from the solar that improves the response with the fast raise in load. The system is validated with MATLAB/Simulink and therefore the output voltage of fused chopper for various solar irradiance and wind speed are tabulated. The output voltage of electrical converter and therefore the motor characteristics are analyzed. Applications/Improvements: For standalone applications within the agriculture water pumping the requirement will satisfy with the hybrid wind solar system.
