Scope, the power output and wind speed for realizing wind power generating set matches, and maximally utilises wind energy,
And the generating set is realized simple structure, low production cost, it is easy to manipulation regulation.
The present invention solve technical problem technical scheme be：A kind of wind power generating set, it includes multiple hairs
Electric unit 20, described generator unit includes excitation rotor 2 and stator 3, and excitation rotor 2 is arranged on master
On axle 1, excitation rotor is located in stator 3, and described main shaft and stator is supported on support, and it is special
Levying is, the main shaft of adjacent generator unit is connected in series, and each excitation rotor is controlled by corresponding controller 41,
On-off of the controller 41 according to the exciting current of the change control excitation rotor of wind-force.
The support 23 of described generator unit is Split type structure, and main shaft and stator are supported on support, phase
The main shaft of adjacent generator unit is connected in series.
It is a feature of the present invention that the exciting current in control excitation rotor can make whether the generator unit generates electricity,
The unit generated electricity when wind-force is big is more, and vice versa.Its advantage is：1st, this generating set can be by one
Frame blower fan drives, and can reduce blower fan quantity, reduces cost of electricity-generating；2nd, generating set can be matched with wind-force
Make full use of wind energy；3rd, the combination of generator is convenient.
