Abstract: Wind power generation is widely concerned all over the world, which greatly promotes the rapid development of wind power generators. With the continuous development of wind power generation technology, it also puts forward more objective requirements for wind turbines, which has led to the emergence of various new topology structures of wind turbines. A comprehensive overview of the development and application of various wind turbines based on relevant literature is provided domestically and internationally. Firstly, the operating principle, structure, advantages and disadvantages of various wind power generators are described in detail. Secondly, the main parameters and performance of all kinds of generator systems are compared and analyzed. Thirdly, the mainstream models, product power and market share of various generator systems in domestic and foreign generator manufacturing enterprises are summarized. Then, the advantages and disadvantages of various new wind turbines are discussed, and the advantages of applying brushless doubly fed generators to wind power generation are pointed out. The structural characteristics and operational performance of hybrid rotor brushless doubly fed generators are elaborated in detail. Finally, the future development direction and research focus of wind power generators are discussed, providing reference for subsequent related research.
