Abstract
A downwind type wind turbine having a transformer stored in a support post or in a nacelle includes the nacelle which supports a rotor and stores therein a generator, a support post which supports the nacelle and a main transformer disposed between the generator and an electric power system and the main transformer is stored in the nacelle or in the support post.
Claims11
A downwind type wind turbine which generates electricity in state that a rotor is disposed downwind, comprising:
- a nacelle to support the rotor and store therein a generator, a support post to support the nacelle and a main transformer arranged between the generator and an electric power system, and
- wherein
- the main transformer is stored in the nacelle or in the support post.
A method of operating a downwind type wind turbine including a main transformer stored in a support post or in a nacelle constructing the downwind type wind turbine which generates electricity in state that a rotor is disposed downwind and positioned between a generator and an electric power system in the downwind type wind turbine and an auxiliary machinery connected to the generator to control the downwind type wind turbine, wherein
- during generation of electricity by the downwind type wind turbine, the auxiliary machinery is operated by electric power generated by the generator so as to control the downwind type wind turbine.
