Method for predicting forest grassland fire caused by power grid dense transmission channel lines

Abstract

The invention relates to the technical field of power grid disaster protection, and discloses a method for predicting a forest grassland fire caused by a power grid dense transmission channel line, soas to perform key defense for high-risk time periods and regions according to a prediction result and prevent forest grassland fire accidents caused by the power grid dense transmission channel line.The method comprises the following steps: dividing dense power transmission channels of a power grid into rectangular grids with the same size; acquiring a vegetation type risk value of a position corresponding to each grid, calculating a thunderstorm weather risk value of each grid according to the Sandstorm index of the predicted time of each grid, and calculating a strong wind weather risk value of each grid according to the wind speed of the predicted time of each grid; and according to the vegetation type risk value, the thunderstorm weather risk value and the strong wind weather risk value, comprehensively predicting the risk level of forest grassland fire caused by the line of each grid.

Description

technical field [0001] The invention relates to the technical field of power grid disaster protection, in particular to a method for predicting forest and grassland fires caused by power grid intensive transmission channel lines. Background technique [0002] Today, with the rapid development of power grids, with the continuous construction of ultra-high voltage and ultra-high voltage lines, the resources of transmission channels are constantly decreasing, and it is becoming more and more common for multiple lines to run parallel, cross, and span in the same transmission channel to form dense transmission channels in the power grid. [0003] Due to the numerous and criss-crossing lines in the grid-intensive power transmission channel, and the location of the grid-intensive power transmission channel is usually in the wild with lush vegetation, complex terrain, and harsh climate environment, the line may fail and cause forest and grassland fires, threatening people's lives and...

Problems solved by technology

[0004] However, due to the wide coverage of power grid-intensive transmission channels, it is difficult to achieve real-time monitoring and deployment everywhere. Therefore, it is urgent to predict the risk of forest and grassland fires caused by grid-intensive power transmission channels, and according to the prediction results, carry out targeted high-risk periods and regions. Focus on defense to prevent forest and grassland fire accidents caused by dense power transmission channel lines in the power grid
