Embodiment Construction

[0049] Such as figure 1 As shown, according to a preferred embodiment of the present invention, it shows the composition and functional block diagram of a transmission line disaster monitoring and risk assessment system based on satellite and meteorological information of the present invention. The system includes a transmission line geographic information subsystem, Satellite remote sensing data receiving subsystem, data modeling and risk assessment subsystem, disaster early warning and disposal subsystem, and support and operation subsystem.

[0050] The geographic information subsystem of the transmission line is used to provide the geographical longitude and latitude coordinates of the transmission line tower and the area where the transmission line passes.

[0051] In a preferred embodiment, the system uses a public system dedicated to the power system.

[0052] The satellite remote sensing data receiving subsystem includes an antenna control module, a receiving channel ...

Abstract

The invention provides a power transmission line disaster monitoring and risk assessment platform based on satellite and weather information in order to effectively warn disasters. The platform comprises a power transmission line geographic information sub-platform, a satellite remote sensing data receiving sub-platform, a data modeling and risk assessment sub-platform, a disaster warning and treatment sub-platform, and a support and operation sub-platform. The data modeling and risk assessment sub-platform comprises a fire development trend prediction submodule; the submodule predicts time sequence of fire data by a time prediction method, auto-regressive integrated moving average, captures cross-fire hidden spatial correlation by a spatial prediction method through dynamic regression neural network, simulates stochastic disturbance by a Markov chain model, and acquires space-time integrated and disturbance-removing prediction results by means of statistical regression.

Description

technical field [0001] The invention relates to a power transmission line disaster monitoring and risk assessment system, in particular to a power transmission line disaster monitoring and risk assessment system based on satellite and meteorological information. Background technique [0002] Economic development has led to continuous growth in power demand, corresponding rapid development of power construction, gradual increase in voltage levels, and continuous increase in power transmission capacity. my country has become one of the countries with the highest AC and DC transmission voltage levels in the world today. With the introduction of policies in recent years to protect the original vegetation, return farmland to forests, and close mountains for afforestation, my country's forest coverage and forest vegetation density have increased significantly. However, my country's energy resources and load centers are distributed in reverse: more than 70% of energy demand is conc...
