Abstract

The invention relates to a satellite-aviation-ground combined forest fire trend early warning method, device and system of a power transmission line channel, and belongs to forest fire trend early warning of the power grid. According to the method, a remote sensing satellite, an unmanned aerial vehicle/helicopter and a power grid online monitoring device are used for monitoring the fire point position, the landform, the vegetation type and the microclimate; a set value of each parameter is obtained through a data receiving and processing module, a forest fire development trend vector diagram is obtained through calculation and deduction via a Rothermel model and a Huygens model, early warning information is obtained through power grid GIS superposition analysis, and the early warning information is sent to a mobile terminal of a manager of an equipment operation and maintenance department. By constructing the satellite-aviation-ground combined forest fire trend early warning system, investment of field operation and maintenance personnel can be reduced, the forest fire monitoring area can be expanded, the forest fire development trend can be quickly predicted, and an objective, accurate and stable data source can be provided for the power grid forest fire development trend.

Description

technical field [0001] The invention relates to the field of early warning of mountain fire trend in power grids, in particular to a method, device, system and storage medium for an early warning method, device, system and storage medium of mountain fire trend in transmission line channels combined with air and ground. Background technique [0002] High-voltage transmission lines often cross densely-vegetated mountainous areas and forest areas. In high-temperature and dry weather, there is a high probability of wildfires, which can easily cause phase-to-phase or phase-to-phase breakdown of nearby transmission lines and cause tripping, which poses a greater threat to power grid security and system stability. Therefore, in order to ensure the safe and stable operation of the line and reduce the tripping of transmission lines caused by wildfires, it is necessary to detect and grasp the development trend of wildfires in time to gain valuable time for the adjustment of the power g...
