[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean and pollution-free renewable energy source. The use of wind power generation is very environmentally friendly, and the wind energy reserves are huge. Therefore, it is increasingly valued by countries all over the world. In the process of wind power generation Wind turbines are usually used in wind turbines, and wind turbines mainly include wind rotors and generators. The wind rotors are composed of blades, hubs and reinforcements. However, most of the existing wind turbines are not convenient to estimate the current wind speed, wind direction and the duration of wind direction change in real time during power generation operation, so it is not convenient to change the blade angle corresponding to the wind speed, and it is not suitable for the wind turbine control strategy , can not achieve the maximum output, resulting in low utilization rate of wind energy, for this reason, we propose a wind condition estimation device for wind turbines
