Research Progress on Energy Conversion Efficiency of Wind Turbine

Abstract

Wind energy occupies an overwhelming advantage in global renewable energy. At present, as a renewable and pollution-free natural energy, wind energy is being valued by people and is expected to become the main source of electricity in Europe, Asia, and North America in the future. A wind turbine is electric power equipment that converts wind energy into mechanical power, which drives the rotor to rotate and finally outputs alternating current. The working principle of the wind generator is that the wind wheel rotates under the action of the wind and converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates under the drive of the wind wheel shaft to generate electricity. This paper will focus on the structure of the active wind system, including the direction of wind direction detector, impeller controller, generator blade structure, location of different areas, and the prediction of wind speed by using artificial intelligence technology as well as the selection of batteries and the optimization of grid connection technology. Through the above aspects put forward a variety of ways to improve efficiency.
