[0002] At present, it is known that wind power generators have contradictions between the uncertainty of wind speed and the need to stabilize the generator speed. At present, the existing wind power generators either do not control the generator speed at all, and let it change with the change of wind speed. Such wind power generation There is a high risk of too fast turbine speed, and the efficiency of the generator is low; at present, there is also a wind turbine that installs a speed control device on the generator, which results in low generator efficiency, complex structure, and high failure rate.

Embodiment Construction
[0008] In the figure, the turbine (1) is connected to the main shaft (3), the main shaft (3) is composed of multiple sets of independent generator rotors (4), and the inside of the generator box (2) is composed of multiple sets of independent generator stators (5); When low, the control switch (7) controls a group of generator rotors (4) and generator stators (5) in the generator casing (2) to work and generate electricity through the generator wires (6); when the wind speed becomes faster, the turbine (1) The absorbed wind energy increases, and the speed of the turbine (1) and the main shaft (3) increases. At this time, the control switch (7) controls the generator rotor (4) and the generator rotor (4) in the generator box (2) through the generator wire (6). The generator stator (5) works to generate electricity; when the wind speed slows down, the control switch (7) controls one group in the generator rotor (4) and the generator stator (5) to stop working, so that when the wi...

The invention discloses a wind-driven generator with stable rotation speed. The generator is driven by a group of turbines; the interior of the generator consists of multiple groups of independent rotors and stators which can generate power individually according to changes in wind speed and can generate power at the same time; the group number of the working rotors and stators in the generator is determined according to different wind speeds; and an electromagnetic force which is required to cut a magnetic field when a group of the rotors and the stators work is constant, and the electromagnetic force which cuts the magnetic field is changed by changing the group number of the working rotors and stators of the generator, so as to adapt to different wind speeds, so that the rotation speeds of the turbines and the generator are unchanged when the wind speed changes constantly.
Description
Technical field [0001] The invention belongs to the electromechanical field and relates to electromechanical design. Background technique [0002] At present, it is known that wind power generators have contradictions between the uncertainty of wind speed and the need to stabilize the generator speed. At present, the existing wind power generators either do not control the generator speed at all, and let it change with the change of wind speed. Such wind power generation There is a risk that the turbine speed is too fast, and the efficiency of the generator is low; at present, there is also a wind generator that installs a speed control device on the generator, which results in low generator efficiency, complex structure, and high failure rate. Contents of the invention [0003] In order to overcome the contradiction between the uncertainty of the wind speed and the stability of the generator speed, make the energy conversion rate of the wind generator higher, reduce the w...
