Embodiment Construction

[0016] Now elaborate the present invention in conjunction with accompanying drawing:

[0017] The wind turbine structure is as follows image 3 As shown, it includes a blade 1, a gearbox 2, a brushless cage asynchronous generator 3 (IG / SG) and an AC-DC-AC full power converter 4; the rotating shaft of the blade 1 is connected to the main shaft of the gearbox 2; The gearbox 2 is connected to a brushless cage asynchronous generator and drives the brushless cage asynchronous generator 3 to rotate; the stator winding of the brushless cage asynchronous generator 3 is connected to an AC-DC-AC full power converter 4 . When in use, the brushless cage-type asynchronous generator 3 of the wind power generating set is connected to the grid 5 through the AC-DC-AC full power converter 4 .

[0018] When working, the blade 1 rotates against the wind, driving the gear box 2 to rotate, and the gear box 2 drives the rotor of the brushless cage-type asynchronous generator 3 to rotate after being...

Abstract

The invention discloses a wind generating set structure which is small in volume and maintenance-free and has good low-voltage ride-through capability. The wind generating set structure comprises a blade, a generator, a gear box and a current transformer, wherein a blade rotating shaft is connected with a main shaft of the gear box; the main shaft of the gear box is connected with a rotor of the generator; the current transformer is connected between the generator and an electric network through a cable; the generator is a brushless cage-type asynchronous generator; the current transformer is a full-power current transformer, and a motor side current transformer of the full-power current transformer is connected with a stator winding of the brushless cage-type synchronous generator; and an electric network side current transformer is connected with the electric network.

Description

Technical field: [0001] The invention belongs to the field of power generation equipment, in particular to a novel structure of a wind power generating set. Background technique: [0002] Energy has become a bottleneck restricting the energy development of various countries. From the perspective of energy development strategy, human beings must seek a sustainable energy path. The purpose of sustainable energy development is development, and the key is sustainability. Moreover, with the development of the economy and the improvement of living standards, people pay more and more attention to the improvement of their living and living environment, and their awareness of environmental protection continues to increase. There is an urgent need for some clean, pollution-free, and renewable new energy sources. Among the many renewable energy and new energy technology developments, wind power is the most mature, most suitable for large-scale development and commercial development pro...
