Abstract

The invention discloses a grid meteorological disaster monitoring and early warning system which comprises a data collection subsystem, a data analysis subsystem, a data storage subsystem and a disaster weather comprehensive display subsystem, wherein the data collection subsystem is responsible for completing a collection task of original meteorological monitoring data. The original meteorological monitoring data is composed of automatic meteorological station data, Doppler radar data, meteorological satellite data and value forecasting data. The data analysis subsystem is responsible for analysis of original meteorological data, cutting a satellite cloud picture, and finally storing processed data into the data storage subsystem. The data storage subsystem is responsible for storing original data of data of various stages and types, including original data, a relational data, a vector data and a picture, the original data is received from a meteorological department, the relational data is analyzed by the data analysis subsystem, the vector data is analyzed by the data analysis subsystem, and the picture is processed by the data analysis subsystem. The disaster weather comprehensive display subsystem is responsible for system function display. The grid meteorological disaster monitoring and early warning system can accurately position grid facilities which are affected by disaster weather.

Description

technical field [0001] The invention relates to a grid disastrous weather monitoring and early warning system based on a geographic information system (GIS) and multi-meteorological data sources, which belongs to the technical field of meteorological early warning of electric power systems. Background technique [0002] Power grid catastrophic weather refers to weather that poses a serious threat to the safe and stable operation of the power grid and causes major damage to power grid facilities, mainly including lightning, strong winds, heavy rain, hail, typhoons, tornadoes, cold waves, frost, heavy fog, and snowstorms. Currently feasible disastrous weather observation technologies include automatic weather station observation, Doppler radar observation, meteorological satellite observation, etc. [0003] With the continuous expansion of the grid scale, the pressure on the safe and stable operation of the grid is increasing. In recent years, severe and extreme weather has o...
