Description

technical field

[0001] The invention relates to the technical field of renewable energy power generation, in particular to a multi-stage wind speed self-adaptive vertical shaft wind power generator system for a universal sail that utilizes wind resources to generate power. Background technique

[0002] As one of the fastest-growing renewable energy technologies and most likely to realize commercialization and industrialization, wind power generation has made great progress in the past 10 years. At present, the world's wind power generation technology is developing towards large-scale single-unit capacity, variable-pitch wind turbines, variable-speed wind turbines, offshore wind farms above the megawatt level and their applicable wind turbines.

[0003] my country is rich in wind energy resources. It is estimated that the wind energy resources that can be developed are equivalent to about 1 billion kilowatts. Even if half of them are developed, there will be 500 million kilow...
