Cut to wind speed.
The lowest wind speed when the wind turbine starts generating electricity is called the cut-in wind speed. Cut-in wind speed refers to the lowest wind speed at the hub height when the wind turbine starts to generate electricity. It is an important parameter of the wind turbine and determines whether the wind turbine can effectively utilize wind energy to generate electricity.
The vertical axis wind turbine is a low-speed wind turbine that converts wind energy into mechanical energy and then into electrical energy. Use wind power to generate electricity and charge the battery to store electrical energy. Chengyuan wind turbine adopts a patented technology that combines permanent magnetic levitation technology and automatic windshield type. It starts at low wind speed and is noiseless. It is a silent wind turbine. It is 10-30% more efficient than similar types of wind turbines. It is widely used in areas with good wind energy conditions, far away from the power grid, or areas with abnormal power grids to supply electricity for lighting, televisions, searchlights, video playback, communication equipment and electric tools.
