Wind power generation is very popular in countries such as Finland and Denmark; China is also vigorously advocating in the western region. The small wind power generation system has high efficiency, but it is not only composed of a single generator head, but also a small system with a certain technological content: wind turbine generator+charger+digital inverter. A wind turbine is composed of a nose, a rotor, a tail wing, and blades. Each part is important, and its functions include: the blades are used to receive wind power and convert it into electrical energy through the nose of the machine; The tail wing keeps the blades facing in the direction of incoming wind to obtain maximum wind energy; Turning can enable the nose to rotate flexibly to achieve the function of adjusting the direction of the tail wing; The rotor of the machine head is a permanent magnet, and the stator winding cuts the magnetic field lines to generate electrical energy.
Generally speaking, the third level wind has value in utilization. But from an economically reasonable perspective, wind speeds greater than 4 meters per second are suitable for power generation. According to measurements, a 55 kilowatt wind turbine has an output power of 55 kilowatts when the wind speed is 9.5 meters per second; When the wind speed is 8 meters per second, the power is 38 kilowatts; When the wind speed is 6 meters per second, it is only 16 kilowatts; When the wind speed is 5 meters per second, it is only 9.5 kilowatts. It can be seen that the greater the wind force, the greater the economic benefits.
In China, there are now many successful small and medium-sized wind power generation devices in operation.
China has extremely abundant wind resources, with an average wind speed of over 3 meters per second in the vast majority of regions, especially in the Northeast, Northwest, Southwest Plateau, and coastal islands, where the average wind speed is even higher; In some places, more than one-third of the year is spent on windy days. In these areas, the development of wind power generation is very promising
