Microclimate disaster early warning method and system based on microclimate and satellite remote sensing data

Abstract

The invention relates to a microclimate disaster early warning method and system based on microclimate and satellite remote sensing data, and belongs to the field of meteorological disaster early warning of an electrical power system. The microclimate disaster early warning method and system are characterized in that the satellite remote sensing technology is applied to power grid meteorological disaster monitoring, and combined application of macrometeorology and microclimate is achieved. Meteorological data in a ground observation database and satellite remote sensing observation data in a satellite remote sensing observation database are transmitted to an early warning platform server through a GSM network. Deep excavation on the observed data is carried out through analytical procedures, statistical information including the maximum value, the minimum value, the average valve and the like within any historical time period are settled, and specific information of the monitoring points is visually described for a user in the mode of graphs, curves and the like. The influence scope of the disaster weather are judged according to the disaster gradation standard,, power grid facilities influenced by the disaster weather are accurately positioned, and data supports and decision supports are provided for disaster prevention, disaster resistance and disaster reducing of power grids.

Description

technical field [0001] The invention belongs to the field of early warning of meteorological disasters in electric power systems, and in particular relates to a method and system for early warning of micro-meteorological disasters based on micro-meteorological and satellite remote sensing data. Background technique [0002] The power industry is an industry with high meteorological sensitivity and high demand, and its production, construction, and operation are greatly affected by environmental meteorological factors. Micrometeorology refers to the change of small-scale meteorological elements (meteorological elements include temperature, humidity, wind speed and direction, air pressure, rain and snow, etc.) in the near-surface atmosphere and in the upper soil due to certain structural features (such as micro-topography). , this small-scale climate characteristic is manifested in individual weather phenomena (such as wind, fog, frost, rime, etc.), but the change of this elem...

AI Technical Summary

Problems solved by technology

[0004] (1) The region is highly targeted, and there are differences in topography, climate, vegetation, etc. in different provinces and cities. The analysis of the regional laws of micro-meteorological disasters is not comprehensive, and theories related to micro-meteorological disasters cannot be used throughout the network;

[0005] (2) The collection of meteorological information is scattered. Meteorological stations (stations) are permanently located in cities and nearby areas, and it is difficult to reflect the actual meteorological conditions of local micro-topographic points such as canyons, tuyeres, and mountain watersheds along the line. However, the meteorological monitoring equipment of the power grid is mostly aimed at a single special disaster. The characteristics of regional micro-meteorology are not fully considered, and the two lack effective integration, and real-time monitoring and broadcasting of micro-meteorological points cannot be carried out;

[0006] (3) There is a lack of professional micro-meteorological and micro-topographic information databases, and the existing micro-meteorological disaster warning calculation and forecast models need to be revised;

[0007] (4) Micro-meteorological disaster monitoring mostly uses online monitoring devices, which have shortcomings such as small monitoring range and limited work under disaster conditions. The application research of power grid wide-area monitoring technology based on satellite remote sensing information in the field of micro-meteorological disaster monitoring has just started, and cannot Support for deeper development and application
