Method, device, equipment and medium for editing wind speed distribution map of power grid

Abstract

The invention discloses a method for revising a wind speed distribution diagram of a power grid, which includes obtaining long-term wind speed data of meteorological stations within a preset range of a typhoon landing point; adding to the original wind speed distribution diagram according to the wind speed data to reconstruct the long-term The wind speed sequence of meteorological station; Obtain the long-term meteorological station that wind speed significantly changes in described long-term meteorological station according to described wind speed sequence; Screen out the automatic weather station that is reference weather station with the long-term meteorological station that described wind speed significantly changes; According to described The wind speed data of the automatic weather station and the reconstruction wind speed sequence of the reference weather station determine the correction coefficient; according to the wind speed data of the automatic weather station, the reconstruction wind speed sequence of the reference weather station and the correction coefficient The original wind speed distribution map is interpolated to obtain the revised wind speed distribution map. The characteristics of typhoons can be considered, and the data of long-term meteorological stations and automatic weather stations can be adjusted in a targeted manner, which improves the editing efficiency.

Description

technical field [0001] The invention relates to the technical field of design and transformation of power transmission lines in disaster prevention and mitigation of power grids, and in particular to a method, device, equipment and medium for editing wind speed distribution diagrams of power grids. Background technique [0002] The design wind speed is a key parameter in the design of overhead transmission lines, and the value of the design wind speed is directly related to the economy, safety and applicability of the line project. At present, the design wind speed of overhead transmission lines is mainly determined based on the wind speed data of long-term meteorological stations near the line corridor, the "Code for Loading of Building Structures" GB50009-2012, and the design wind speed of existing lines in the same area. The southeast coastal areas of our country are severely hit by typhoons, and the wind and disaster mitigation situation of transmission lines in coastal ...

AI Technical Summary

Problems solved by technology

However, in the nine typical meteorological regions provided in Appendix A, the basic wind speed classification is relatively general. For those trans-regional transmission lines, there is a large difference between the actual wind speed and the design wind speed

And in the case of insufficient meteorological data and lack of operating experience along the line, corresponding meteorological data statistics work is still required, which also brings difficulties to the design and operation and maintenance of transmission lines
