Method for measuring power generation capacity index of regional wind power plant

The invention discloses a method for measuring a power generation capacity index of a regional wind power plant. At present, wind power density is generally adopted as an index for measuring regional wind energy resource reserves, so that the regional wind energy reserves cannot be comprehensively assessed; for the problem, the method is used for assessing a wind energy distribution condition of regional wind energy resources in a longitudinal height, and mainly comprises the following steps of S1, performing integral on the longitudinal height and a wind speed by adopting a double integral mathematic method in combination with a two-parameter Weibull probability density function based on a theorem of kinetic energy and an energy conservation law, and building a regional wind power plant mathematic model; S2, calculating the wind energy reserves between to-be-assessed height layers of a given region in combination with an effective wind speed and a range of the to-be-assessed height layers by utilizing the re
