Power transmission line wind speed correction method and system based on terrain parameters

Abstract

The invention relates to the technical field of power transmission line meteorological environment analysis, in particular to a power transmission line wind speed correction method and system based on terrain parameters, and constructs a set of systematized and computable power transmission line wind speed correction process with high engineering practicability. The problem that in the prior art, wind speed correction is difficult to achieve rapidly and systematically between complex terrains is effectively solved. Through progressive analysis of terrain space data preprocessing, terrain feature vector construction and terrain type recognition, an abstract terrain form is converted into a quantifiable parameter system, and a data foundation is laid for accurate modeling; and through the core steps of wind speed acceleration ratio model construction and standard wind speed model coupling, computable expression of wind speed field terrain influence is realized, a three-dimensional correction result better conforming to actual wind field physical characteristics is generated, and data availability and engineering efficiency are significantly improved.
