Wind energy is regarded as a clean renewable energy source, and is increasingly paid more attention by countries in the world, so that kinetic energy of wind is converted into mechanical kinetic energy, and then the mechanical energy is converted into electric kinetic energy, namely wind power generation. The principle of wind power generation is that wind power drives windmill blades to rotate, and then the rotating speed is increased through a speed increaser, so that a generator is promoted to generate electricity. According to current windmill technology, the power generation can be started at a breeze speed of about three meters per second. Wind power generation is forming a hot tide in the world because it does not require the use of fuel and does not produce radiation or air pollution. The devices required for wind power generation are called wind generating sets. The wind generating set can be divided into three parts, namely a tail vane, a generator and a tower.
