example 1

[0092] Example 1: Taking the corridors of 500KV and 220KV transmission lines in Shanxi Province as an example, combining figure 1 , adopt analysis method described in the present invention, carry out section meteorological analysis to transmission line corridor, concrete steps are as follows:

[0093] Step S1: build a GIS platform: use conventional methods to build a GIS platform, and load weather information from public network weather stations and power grid micro-meteorological monitoring stations on the GIS platform to obtain a GIS system;

[0094] Among them, the geographic information data in the GIS system adopts the 1:250,000 Shanxi basic geographic background data provided by the National Basic Geographic Information Center, and extracts the required geographic information through processing, including administrative divisions, digital elevation models (DEM) and Longitude, latitude, altitude, slope, aspect and other raster data, the grid spacing of all raster data is ...

Abstract

The present invention is a method for analyzing meteorological conditions of power grid transmission line sections, wherein a method for analyzing meteorological conditions of power grid transmission line sections includes: step S1: building a GIS platform, and step S2: obtaining a GIS system for storing transmission line corridor information , step S3: delineate the meteorological analysis area, step S4: grid the meteorological analysis area, step S5: divide the transmission line section, step S6: establish the meteorological resource estimation model, and obtain the corrected model through grid estimation and residual correction climate resource distribution map, step S7: Meteorological analysis of the transmission line corridor section, this method puts the meteorological factors and micro-meteorological factors on the transmission line of the power grid on the same analysis and display platform, which solves the problem of low accuracy of meteorological analysis of transmission lines and The problem of high economic cost caused by installing a large number of micro-meteorological monitoring stations.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to a method for analyzing meteorological conditions of power grid transmission line sections. Background technique [0002] In recent years, with the continuous expansion and extension of the scale of the power grid, disastrous weather such as freezing, heavy (rain) snow, typhoon and other disastrous weathers have an increasing impact on the safe operation of the power grid. Therefore, it is imperative to understand the characteristics of meteorological disasters in this region and analyze the impact on the power system. According to the 14 kinds of disastrous weather information provided by the meteorological department, such as lightning, heavy rain, heavy fog, high temperature, and drought, the electric power department will plan ahead and conduct more accurate scientific scheduling to prevent the gate from moving forward. [0003] In addition to the i...
