Abstract

The invention relates to an electric generator, and belongs to the technical field of electricity generation. The electric generator comprises a wind wheel capable of independently changing pitch, a transmission gear box, a sealed vertical cabin, an electric control cabinet, an electric generator body, and a yaw device, wherein the wind wheel is connected with the electric generator body in the vertical cabin through the transmission gear box; the vertical cabin is placed at the top end of a pylon; and the yaw device is arranged between the vertical cabin and the pylon. The electric generatordisclosed by the invention adopts the vertical cabin, so that the whole cabin is compact, and a cabin hood is removed; the generator is high in anti-typhoon capacity; and the electric generator adoptsmanners of independent pitch changing and wind wheel intelligent panel control, so that the load of wind mill blades and the load of the pylon can be effectively retarded, the life of the wind mill is prolonged, and the reliability of the wind mill is improved.

Description

technical field

[0001] The invention belongs to the technical field of power generation, and in particular relates to a generator. Background technique

[0002] Offshore wind resource conditions are better than those on land, and offshore wind power generation has unique advantages, and its development has attracted great attention from governments around the world. In order to reduce the average cost of manufacturing, transportation, installation and maintenance, etc., and then reduce the cost of electricity per unit area and increase the power generation per unit area, the unit capacity and blade size of offshore wind turbines continue to grow steadily. At present, the rated power is generally between 1MW and 5MW, and wind turbines that can successfully operate with a maximum rated power of 6MW have been successfully installed in the United States, Europe, and China. A large wind turbine with a rated power of 10MW (rotor diameter 144m) or even a rated power of 20MW (diame...
