Problems solved by technology

[0003] At present, the grid-connected wind turbines are mainly indirect drive grid-connected wind turbines. A speed-up gearbox is installed between the generator and the wind rotor of the indirect drive grid-connected wind turbines. The wind rotor has a low speed, and the generator It is a high-speed wind turbine. Because of the gear box, the maintenance of the wind turbine is large and the reliability is low, so the equivalent utilization time of the wind turbine is low.

Embodiment Construction

[0010] With reference to the accompanying drawings, the present invention includes a remote monitoring computer 8, a tower 7, a wind wheel, a yaw system 5, a wind vane 6, an electric control system 11 for a nacelle, and an electric control system 10 under a tower. Composed of a cover and a hub 1, one or more generators 4 are connected to the shaft of the wind rotor through a mechanical series connection. The specific connection is that the generator rotor utilizes the transmission shaft 3 and the shaft coupling 13 to carry out mechanical serial connection with the shaft of the wind wheel, and as a result, the generator rotor and the shaft of the wind wheel rotate synchronously. In direct drive grid-connected wind turbines, when the number of generators is single, asynchronous generators should be used; when the number of generators is more than one, each generator should use asynchronous generators or synchronous generators, Including permanent magnet synchronous generators. ...

Abstract

The invention relates to a directly driven interconnected windmill generator set, which comprises the long-distance monitoring computer, the tower barrel, the vane, the yaw system, the weather vane, the cabin electric control system, the tower bottom electric control system. The characteristics are: without the gear box the radial length of the set can be greatly reduced to solve the erosion, the noise and the wearing problems brought by the revolving of the gear box and to maintain the life span of the set and to protect the environment.
