The function of the generator is to transfer the constant rotational speed obtained by the wind wheel to the power generating mechanism to run evenly through the speed increase, thus converting the mechanical energy into electrical energy.
Wind power is popular in countries such as Finland and Denmark; China is also strongly promoting it in the western region. The small wind power generation system is very efficient, but it is not composed of only one generator head, but a small system with certain technological content: wind generator + charger + digital inverter. A wind turbine consists of a nose, a swivel, a tail, and blades. Each part is very important, and the functions of each part are: the blades are used to receive the wind and turn into electrical energy through the nose; the tail makes the blades always face the direction of the incoming wind to obtain the maximum wind energy; the swivel can make the nose flexibly rotate to achieve The function of adjusting the direction of the tail; the rotor of the nose is a permanent magnet, and the stator windings cut the magnetic lines of force to generate electricity.
Generally speaking, the tertiary wind has the value of utilization. But from an economical and reasonable point of view, wind speed greater than 4 meters per second is suitable for power generation. According to the determination, a 55-kilowatt wind turbine, when the wind speed is 9.5 meters per second, the output power of the unit is 55 kilowatts; when the wind speed is 8 meters per second, the power is 38 kilowatts; when the wind speed is 6 meters per second, only 16 kilowatts; and when the wind speed is 5 meters per second, it is only 9.5 kilowatts. It can be seen that the greater the wind, the greater the economic benefits.
In my country, there are many successful medium and small wind power plants in operation.
my country’s wind resources are extremely rich, and the average wind speed in most areas is more than 3 meters per second, especially in the northeast, northwest, southwest plateaus and coastal islands, the average wind speed is even greater; in some places, more than one third of the year. The times are windy days. In these areas, the development of wind power generation is very promising.
