Abstract

The invention discloses a wind field data refinement processing method and device, a terminal and a medium. The method comprises the steps of acquiring wind field data and topographic data of a target area; constructing a grid model of the target region according to the wind field data and the topographic data; according to the average gradient of the grid units in the grid model, determining the terrain correction factors of the grid units in combination with the corresponding relation between the gradient numerical values and the terrain correction factors; according to the wind field data of the grid units, combining calculation of an inverse distance weighting method lattice interpolation formula, and obtaining interpolation wind field data of the grid units; and according to the grid model, performing product calculation on the interpolation wind field data of the same grid unit and the terrain correction factor to obtain lattice wind field data of the target region. According to the meteorological station observation data and the topographic data, the meteorological data space-time distribution characteristics with higher precision are obtained by using the interpolation method, and the technical problem of insufficient precision of an existing wind field simulation mode is solved.

Description

technical field [0001] The present application relates to the technical field of wind field processing, and in particular to a wind field data refinement processing method, device, terminal and medium. Background technique [0002] my country has huge reserves of wind power resources, but it is also extremely vulnerable to strong winds and typhoons. Statistics in recent years show that with global warming and frequent extreme weather, the accident rate of transmission lines caused by strong winds is increasing year by year. Strong winds have brought severe challenges to the safe and reliable operation of urban power grids. [0003] At present, the power grid department obtains the corresponding wind field simulation data by means of wind field simulation early warning forecast, and uses the obtained simulation data as a reference to carry out disaster prevention and mitigation of transmission lines, so as to improve the ability of power grid equipment to resist strong wind ...
