The principle of a wind turbine is to use wind energy to turn the blades of the wind turbine, then increase the rotation speed using a speed multiplier to encourage the generator to produce electricity.
The small wind power generation system is very efficient, but it is not only composed of a generator head, but a small system with certain technological content: wind turbine, charger and digital inverter.
The wind turbine consists of a nose, a rotor, a tail and blades. Each part is very important. The blades are used to receive wind energy and convert it into electrical energy through the nose. keeps the blades facing the direction of the incoming wind to obtain maximum wind energy; the pivot allows the nose to rotate flexibly to realize the function of adjusting the direction of the tail. The nose rotor is a permanent magnet and the stator winding cuts ; magnetic lines of force to generate electrical energy.
Mechanical connection and power transmission of wind power generation
The blades of the horizontal axis wind turbine are connected to the universal elastic coupling via the gearbox and its high-speed shaft to transmit torque to the transmission shaft, this coupling must have good vibration damping and absorption characteristics, which results in absorbing an appropriate amount of radial deviations, axial and certain angular deviations, and the coupling can prevent overloading of the mechanical device.
The other type is the direct drive type of fan motor in which the blades are directly connected to the motor without passing through the gearbox.
