Description

technical field [0001] The invention relates to a megawatt-level water-cooled double-fed asynchronous wind generator. Background technique [0002] Wind turbines have developed rapidly in recent years because they are clean energy power generation equipment. However, the high-power megawatt-class water-cooled doubly-fed asynchronous wind turbine is currently one of the key development models, and it is still in the research and development stage in China. There are some technical problems that need to be solved. The main problems are two, one is that the power quality needs to be improved, and the other is that the work reliability must also be improved. Contents of the invention [0003] The object of the present invention is to provide a megawatt water-cooled double-fed asynchronous wind generator, which can greatly improve the power quality and reliability of the megawatt water-cooled double-fed asynchronous wind generator. [0004] The present invention is realized i...
