Wind turbine manufacturer

1. Large wind turbine manufacturers include Goldwind Technology, Huarui Wind Power, Dong Qi, etc. Small fans: Hong Ying, Shenzhou Wind Power, Zhongke Hengyuan, etc. 2. Wind generator: it is an electrical device that converts wind energy into mechanical work, drives the rotor to rotate, and finally outputs alternating current. In a broad sense, wind energy is also solar energy, so it can also be said that wind turbine is a kind of thermal energy utilization generator with the sun as the heat source and the atmosphere as the working medium. 3. Wind turbine type: (1) asynchronous type: cage asynchronous generator and wound doubly-fed asynchronous generator. (2) Synchronous type: permanent magnet synchronous generator and electric excitation synchronous generator. (3) Horizontal axis: the most widely used form in the world at present, with a maximum power of about 5MW. (4) Vertical axis: A new type of wind turbine invented by China, Japan and Europe in the early 20th century, which is different from the earliest vertical axis wind turbine (Darieu type), with higher efficiency than horizontal axis wind turbine, no noise and steering mechanism, and simple maintenance.
