Wind power generation refers to converting kinetic energy of wind into electric energy. Wind energy is a clean and pollution-free renewable energy source, and is used by people for a long time, mainly by pumping water, grinding surfaces and the like through windmills, and people are interested in how to use wind to generate electricity. The wind power generation is very environment-friendly, and the wind energy is huge, so that the wind power generation is increasingly paid attention to all countries in the world, the kinetic energy of wind is converted into mechanical kinetic energy, and then the mechanical energy is converted into electric kinetic energy, namely the 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 the windmill technique, a breeze speed (of the order of three meters per second) can be used to generate electricity. 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 wind wheel (comprising a tail vane), a generator and a tower. The wind wheel is an important part for converting the kinetic energy of wind into mechanical energy and consists of a plurality of blades. When wind blows to the blades, aerodynamic force is generated on the blades to drive the wind wheel to rotate. The blade is made of a material which is required to have high strength and light weight and is made of glass fiber reinforced plastics or other composite materials (such as carbon fibers).
