Wind speed prediction method and device

Abstract

The invention provides a wind speed prediction method and device, and the method comprises the steps: obtaining the meteorological simulation data of a target region in a preset meteorological mode; according to the wind speed change characteristics of the simulated wind speed at each grid point of the target area derived from the meteorological simulation data, dividing all grid points of the target area into different groups, wherein the grid points in the same group have the same or similar wind speed change characteristics; determining a region where each divided group is distributed; prediction an actual wind speed at another point other than the point in the region of each group distribution based on the actual wind speed observed at any point in the region of each group distribution. By the adoption of the wind speed prediction method and device, wind resources can be accurately evaluated under the condition of insufficient wind measurement or even no wind measurement, and the uncertainty of calculation of the generating capacity of the wind power plant can be effectively reduced.

Description

technical field [0001] The present application relates to the technical field of wind power generation, in particular to a wind speed prediction method and device. Background technique [0002] The accuracy of wind farm power generation calculation is a key issue that the wind power industry has been working on, and the accuracy of wind farm power generation calculation depends on the accuracy of wind measurement data. However, with the shortening of the investment and construction period for wind farms and the lack of awareness of the importance of wind measurement data, if a wind power project starts to evaluate the wind resources of wind farms under the condition of insufficient wind measurement or no wind measurement at all, It will bring great uncertainty to the calculation of wind farm power generation and the estimation of corresponding income. [0003] Therefore, there is an urgent need for a wind speed prediction method and device that can solve the above problems,...
