Abstract

This application discloses a method and system for drawing a risk distribution map of mountain fire trips on transmission lines. In addition to considering vegetation type parameters, combustible material load parameters and meteorological parameters, the risk level of fire point density is also used as a factor affecting the risk of mountain fires. The level factor avoids the deviation caused by the inhomogeneity and discontinuity of the distribution of combustibles under the mountainous transmission corridor. Monitoring the transmission line mountain fire trip risk distribution map in the entrusted area, which improves the risk prediction accuracy of the transmission line mountain fire trip risk, and solves the problem that the prediction accuracy of the existing transmission line mountain fire trip risk prediction method is not high enough to provide power grid. Technical Issues for Reliable Wildfire Prevention and Control Guidance.

Description

technical field [0001] The present application relates to the technical field of mountain fire prevention and control, and in particular to a method and system for drawing a distribution map of mountain fire trip risk of transmission lines. Background technique [0002] With the advancement of energy technology, transmission lines are developing from short-distance and small-capacity models to long-distance and large-capacity models. Most transmission line corridors pass through forests or mountains with high surface vegetation coverage and harsh terrain conditions. Affected by human factors and natural factors, mountain fire disasters occur frequently. Under wildfire conditions, multiple transmission lines tripped simultaneously or successively, causing large-scale power outages and seriously endangering the normal and stable operation of the power grid. Therefore, it is necessary to study the risk assessment method of mountain fire tripping on transmission lines and draw ...
