Embodiment Construction

[0032] The technical solutions in the present invention will be clearly and completely described below in conjunction with specific embodiments.

[0033] An embodiment of the present invention provides a method for evaluating the environmental fire danger level of a transmission line corridor, which includes the following steps:

[0034] A method for assessing the environmental fire danger level of transmission line corridors, comprising the following steps:

[0035] Step 1, using the transmission line tower coordinates to generate a plus or minus 1km transmission line buffer vector file;

[0036] Step 2. Use the transmission line buffer vector file and land cover classification data to perform vector overlay calculation to obtain the vegetation classification data map in the transmission line corridor buffer area; specifically, the global coverage of 30m resolution land cover data can be used to combine with the transmission line Buffer overlay calculation to obtain vegetati...

Abstract

The invention provides a power transmission line corridor environment fire danger class evaluation method. According to the method, a woodland fire danger class nearby a power transmission corridor is determined according to a plurality of satellite remote sensing data, real-time meteorological essential factor monitoring data of a ground weather station and the ground vegetation coverage information, four fire danger factors of the power transmission corridor vegetation woodland coverage ratio V, the rainfall to fire danger class influence factor R, the TVDI index to fire danger grade influence factor M and the landform to fire danger class influence factor T are comprehensively utilized, quantitative parameter guidance is provided for power transmission corridor area safety fire prevention monitoring on different areas in different seasons through fusion and superposition of multiple fire danger factors.

Description

technical field [0001] The invention relates to the technical field of transmission line operation and maintenance, in particular to a method for evaluating the environmental fire danger level of transmission line corridors. Background technique [0002] The fire in the transmission line corridor area not only causes harm to the ecological environment of the covered area, but also easily leads to the tripping of the transmission line, which brings significant economic losses to the production, operation and maintenance of power supply. From the perspective of power grid operation safety, in order to avoid losses caused by line tripping, it is usually necessary to design the transmission line as a loop to ensure the safety of power supply. However, my country's current energy structure is that hydropower and coal are located in the northwest, while economically developed regions are located in the southeast, which leads to an extremely unbalanced power transmission, making th...
