As an alternative embodiment, the present embodiment further includes a control cabinet 40, and the functional device 22 of at least one cabin unit 20 is electrically connected to the control cabinet 40, and the corresponding functional device 22 is controlled by the control cabinet 40. Alternatively, the control cabinet 40 may be disposed within the shield 30.
It will be appreciated that the above embodiments of the present invention provide a nacelle assembly 100, wherein the connection between the nacelle unit 20 and the nacelle interface 14 includes a plug protrusion, and another plug groove, and the plug protrusion matches with the shape of the plug groove and is connected by plug. This is an alternative embodiment, but not limited to the above, and in some other embodiments, the nacelle interface 14 may also include a first flange, the supporting frame 23 includes a second flange, and the first flange and the second flange are matched in shape and connected to each other, which can also meet the connection requirement between each nacelle unit 20 and the connecting base 10.
The number of the nacelle units 20 included in the nacelle assembly 100 provided by the above embodiments of the present invention can be set according to the power requirement of the wind turbine generator system.
For example, when the wind power generating set applied to the nacelle assembly 100 is a 6MW set, the nacelle assembly 100 may include two nacelle units 20, the upper limit of the post-processing of the converted power of the generator 400 by the functional device 22 of each nacelle unit 20 is 3MW, and the two 3MW nacelle units 20 can realize the post-processing requirement of the converted power of the generator 400 of the 6MW set, so as to meet the power requirement of the 6MW set.
For another example, when the wind turbine generator set applied to the nacelle assembly 100 is a 7.5MW set, the nacelle assembly 100 may also include two nacelle units 20, wherein the upper limit of the post-processing of the converted electrical energy of the generator 400 by the functional device 22 of one nacelle unit 20 is 3MW, and the upper limit of the post-processing of the converted electrical energy of the generator 400 by the functional device 22 of the other nacelle unit 20 is 4.5MW, so as to meet the power requirement of the 7.5MW set.
