Small wind turbine generators are also installed in scattered locations such as rooftops or farmland to supply power to localized areas. The basic principle of wind power generation is to convert the kinetic energy of wind into electrical energy. The specific process is as follows: the kinetic energy of the wind is converted into mechanical energy; the wind turbine blades rotate under the push of the wind, converting the kinetic energy of the wind into mechanical energy, which is then converted into electrical energy; the rotating impeller increases its speed through a speed increaser, driving the generator to generate electricity; and the electricity generated by the generator is stepped up by a substation and then transmitted to the user end through the power grid.

However, existing windmills may encounter strong winds during use, causing the windmill blades to rotate at high speeds due to the wind force, which can lead to the windmill blades breaking.
