Embodiment Construction

[0020] The above objects, features, advantages and preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] figure 1 A schematic diagram of the overall structure of the array type frequency-stabilized permanent magnet wind power generator according to a preferred embodiment of the present invention is shown. figure 2 It shows the structural schematic diagram of the stator and the rotor of the array type frequency-stabilized permanent magnet wind power generator when the end cover is removed. It can be seen from the above two figures that the array-type frequency-stabilized permanent magnet wind power generator includes a stator 2 and two end covers 4 respectively installed at both ends thereof. The stator 2 and the two end covers 4 form a cavity, on which The motor shaft 1 of the stator 2 is arranged coaxially and protrudes outward from the cavity. A rotor 3 is also installed on the motor shaft 1 ...

Abstract

The invention discloses an array type frequency-stabilizing permanent magnet wind-driven generator. A plurality of stators and rotors are arranged into an array type structure, one group of stators can work only, or a plurality of groups of stators can simultaneously work in the array type structure, so that the generator can meet the requirements of multi-level loads. At the same time, each stator winding is connected with a single switch, the number of the windings connected with the stators is controlled by controlling the opening and closing of each switch to further control the rotating speed of the rotors so as to adjust the output voltage frequency of the generator and make the output voltage frequency of the generator kept in a stable value.

Description

technical field [0001] The invention relates to a wind power generator, in particular to an array type permanent magnet wind power generator capable of stabilizing the output voltage frequency. Background technique [0002] In recent years, under the general trend of saving energy and protecting the environment, the wind power industry has developed rapidly. As we all know, the core component of wind power generation, that is, the wind generator is driven by the wind to rotate the blades, and then drive the rotor to rotate, so that the coil cuts the magnetic force lines to generate current. When the number of turns of the winding coil and the strength of the magnetic field are fixed, the voltage frequency of the wind turbine is proportional to the rotational speed of the rotor. Therefore, as long as the rotational speed is constant, the voltage frequency of the wind turbine can remain constant. However, what often happens is that as the wind energy changes, its driving for...
