A Calculation Method of On-Site Meteorological Information for the Whole Transmission and Transformation Line

Abstract

The invention discloses a method for calculating whole circuit in-place weather information of an electric transmission and transformation circuit. The method includes the following steps: (1) segmentation analysis is carried out the electric transmission and transformation circuit through an electric transmission circuit whole-circuit decomposing module, the positions of circuit devices at representative points are determined, and then the analyzed position information is transmitted to an electric transmission and transformation circuit real-time weather information calculating module and an electric transmission and transformation circuit prediction weather information module; (2) weather real-time information of the positions of the representative points of the electric transmission and transformation circuit is completely calculated by collecting data of automatic weather stations along the electric transmission and transformation circuit through the electric transmission and transformation circuit real-time weather information calculating module; (3) weather prediction information of the positions of the representative points of the electric transmission and transformation circuit is completely calculated by an electric transmission and transformation circuit prediction weather information calculating module through grid point data of numerical weather prediction; (4) the weather real-time information and the weather prediction information of the whole circuit are gathered by an information issuing module and displayed on a power grid weather system platform. According to the method, circuit in-place weather real-time data and prediction data in 1 hour-72 hours in future can be generated.

Description

technical field [0001] The invention relates to a method for calculating on-site meteorological information of all lines of power transmission and transformation lines, belonging to the technical field of meteorological disaster warning in electric power systems. Background technique [0002] Transmission lines are main arteries of electric energy that run through cities, suburbs, mountains, and plateaus. In recent years, the UHV transmission lines of the State Grid Corporation of China have advanced rapidly, and the information on meteorological conditions around the transmission lines has attracted more and more attention. However, transmission lines, especially Most of the transmission lines of the backbone network are built in mountainous areas and are distributed in a narrow and long linear shape. The surrounding environment is outside the forecast range of the meteorological department and there is no automatic weather observation station coverage. The real-time meteoro...

AI Technical Summary

Problems solved by technology

[0004] 1) Existing methods cannot summarize and analyze the meteorological information of the entire line, and cannot calculate the weather information for most lines distributed in mountainous areas or plateaus.

[0005] 2) Existing methods can only calculate real-time meteorological information, but cannot calculate weather forecast information, and cannot calculate meteorological disaster early warning in the later stage

[0006] 3) The existing method is only a simple copy of the information of the surrounding weather stations, the value is not comprehensively analyzed and calculated, and the accuracy of the value is low

[0007] 4) The establishment of electric automatic weather stations around the lines requires a large investment, and the investment in inter-provincial trunk lines is too large
