Performance Analysis and Control of Autonomous Wind System with Afpsg Feeding

Abstract

The generate mechanical power or electricity is known as wind power or wind energy, Wind turbines convert the wind's kinetic energy into a mechanical energy-based combination of two or more energy sources that generate efficient energy power. In the existing method autonomous wind-solar hybrid energy system feeding 3-phase 4-wire loads, and it Contains some drawbacks output, not efficiency, high maintenance, Power quality is low, overcome the drawbacks wind system with AFPM feeding to improve power quality.Axial-Flux Permanent Magnet Generator for small wind turbine power generation systems with brushless motors synchronous machine. Because the generator's mechanical frequency changes, the rotor switching frequency must start changing to maintain the stator switching frequency constant. In a wind generator with variable speeds, low balanced dynamical stack, and varying wind accelerations, rotor excitation is permitted for a wind turbine's stator to supply a load or feed the grid. A boost converter is used to increase the DC voltage of the battery before it is given to the single-phase DC-DC Chopper, and the MPPT (Maximum Power Point Tracking) technique is used to maximize the energy output.When the switch is open, no current flows through it, converting the unregulated DC input to a controlled DC output with the desired voltage level, there is no voltage drop across the switch when it is closed in the DC-DC Chopper. The proposed system is simulated using MATLAB Simulink, the output result is improved and getting better efficiency when compared to the proposed method.
