Abstract

The invention relates to a mixed type wind turbine generator system which comprises a horizontal axis power generator and a vertical axis power generator which are installed on one tower. The horizontal axis power generator is connected with a horizontal axis air wheel through a horizontal axis gear case, the vertical axis power generator is connected with an H type vertical axis air wheel through a vertical axis gear case, and the H type vertical axis air wheel rotates around an internal center line; and a stepless speed reducer is connected between the gear case of the horizontal axis power generator and the horizontal axis power generator, the stepless speed reducer is connected with vertical axis gear case through a conical tooth connecting mechanism, the horizontal axis gear case has the function of achieving rotation inversing of a shaft, and it is guaranteed that two shafts connected through the stepless speed reducer rotate in the same direction in the startup state. The mixed type wind turbine generator system which is low in power generation cost, high in power density, high in air energy using efficiency and high in output electric energy quality.

Description

technical field [0001] The invention relates to a wind power generator set, especially a hybrid wind power generator set. Background technique [0002] Wind power generation is an important renewable energy utilization method, which has a series of advantages such as high efficiency and environmental protection. In recent years, wind power technology has achieved continuous and rapid development. my country's wind power development is mainly concentrated after 2003, especially driven by wind power concessions. In 2006, my country added 1,454 wind turbines except Taiwan, increasing installed capacity by 1.337 million kw, which is less than the total accumulated development in the past 20 years. many. By the end of 2008, the total installed capacity reached 12.153 million kw, a year-on-year increase of 106%, ranking among the world's largest wind power countries with installed wind power capacity exceeding 10 million kw. [0003] Wind turbines can be divided into horizontal ...
