The invention discloses a wind power generation wind resource site selection method in the technical field of wind power generation. The wind power generation wind resource site selection method provided by the invention comprises five steps, and finally, the optimal wind resource site selection is realized according to the calculated economic coefficient. The wind power generation wind resource site selection method has the characteristic of providing a wind resource optimal site selection method based on the unified index economic coefficient, which fully considers the power generation capacity of a wind driven generator unit at different wind speeds and the economic benefit change characters caused by the wind direction fluctuation and turbulence intensity influence and the interlocal electric valance difference. Through solving a characteristic power curve, the method is also applicable to the wind power generation wind resource macro quick site selection.
Description
technical field [0001] The invention belongs to the technical field of wind power generation, and relates to a site selection method for optimizing wind resources of wind power generation based on calculating economic coefficients. technical background [0002] Wind energy is currently the most economically valuable renewable energy source. According to the "China Wind Power Development Roadmap 2050" issued by the Energy Research Institute of the National Development and Reform Commission, China's wind power development goals for the next 40 years: by 2020, 2030 and 2050, wind power installed capacity The capacity will reach 200 million, 400 million and 1 billion kilowatts respectively, and by 2050, wind power will meet 17% of domestic electricity demand. [0003] At present, wind turbines have become the main equipment for wind energy utilization, and the cost of wind power generation is still significantly higher than that of traditional thermal power and hydropower genera...
