  • Wind energy utilization factor and wind turbine efficiency The theory shows that when all the kinetic energy of the air close to the wind wheel is absorbed by the rotating wind wheel blades, the air behind the wind wheel will stop flowing, but this is obviously impossible. Therefore, even if the wind energy that passes […]

  • After understanding the basic types of wind turbines, we then analyze their working principles. From the perspective of physics, its working principle is: when the wind blows on the wheel plane of the wind turbine, the wind wheel will be thrust by the wind, and then torque will be formed, and the torque will promote the […]

  • 1. Horizontal axis wind turbine At present, the vast majority of grid-connected wind turbines use horizontal-axis wind turbines, and their shape and structure are shown in Figure 1. The rotor of the wind turbine is installed on the top of the tower where the wind is strong and the turbulence is small. At the same […]

  • Description of wind Wind is a moving airflow and a vector. People generally describe it with three parameters: wind direction, wind speed, and wind level, as follows: (1) Wind direction. In daily life, people are always accustomed to calling the direction the wind blows as wind direction. If the wind is blowing from the south, […]

  • As we all know, the earth we live on is surrounded by a layer of air thousands of meters thick, and the horizontal movement of the air relative to the ground is called wind. Under normal circumstances, according to different scales of atmospheric circulation, wind can be divided into three types, namely atmospheric circulation, monsoon […]
