Wind power generation units refer to other forms of energy into electrical machinery equipment, consisting of wind wheels, air -to -air devices, head seats and rotors, speed regulating devices, transmission devices, brakes, generators and other equipment. At this stage, wind power generation units are widely used in science and technology, agricultural production, national defense and other aspects. The formats of generators are diverse, but their principles are based on the law of electromagnetic force and electromagnetic induction. Therefore, its structure principles are: use appropriate conductive materials and magnetic materials to form an inductive circuit and magnetic circuit, thereby generating electromagnetic power to achieve energy conversion Effect.
When the wind power generation unit is generated, the frequency of the output is constant. This is very necessary whether it is complementary to the scenery and the wind turbine. In order to ensure that the frequency is constant, on the one hand, it is necessary to ensure that the speed of the generator is stable, that is, the operation of the constant frequency and constant speed. Because the generator unit runs through the transmission device, it must maintain a constant speed to avoid affecting the conversion efficiency of wind energy. On the other hand, the rotation speed of the generator changes with the wind speed, and the frequency of electrical energy is constant with the help of other means, that is, the constant frequency operation. The wind energy use coefficient of the wind power generation unit has a direct relationship with the leaf tip speed. There is some clear leaf tip speed ratio to the largest CP value. Therefore, in the case of constant speed of the transmission, the rotation speed of the generator and the wind turbine has some changes, but it does not affect the output frequency of electrical energy.
