Abstract

The present invention relates to the field of meteorological disaster early warning of an electrical power system, and discloses an electric transmission line rainstorm disaster fine prediction methodand system based on an inverse algorithm which are used to refine a rainstorm disaster prediction result to a concrete electric transmission line. The method comprises the steps of: generating a rainfall lattice point prediction file comprising rainstorm disaster index prediction value of each lattice point through a rainstorm disaster prediction and calculation model, and employing the space search of a power grid GIS to perform space intersection for the electric transmission line tower coordinate information and obtain the electric transmission line tower information of a rainstorm area; employing a power grid GIS space line to form electric transmission line space information of a rainstorm disaster; and employing a meteorological factor space interpolation method and combining the electric transmission line of the rainstorm disaster influence to generate an electric power line rainstorm disaster prediction and early warning distribution map through the rainstorm disaster prediction lattice point file, employing the same color to describe the electric transmission lines in the same rainstorm disaster index, and employing other colors to distinguish the electric transmission lines in different rainfall indexes.

Description

technical field [0001] The invention relates to the field of early warning of meteorological disasters in electric power systems, in particular to a refined prediction method and system for rainstorm disasters of transmission lines based on an inversion algorithm. Background technique [0002] In recent years, with the frequent occurrence of heavy rainfall in summer, it is easy to cause geological disasters such as collapses, landslides, mudslides, ground fissures, and soil erosion around the transmission lines, which will cause great harm to the safe operation of the power grid and cause major economic losses and social losses. influences. Considering that the power industry is an industry with high meteorological sensitivity and high demand, once the meteorological elements (including temperature, humidity, wind speed and direction, precipitation, etc.) change, it may cause meteorological disasters such as heavy rain and strong wind, as well as secondary disasters and thre...
