Abstract

The invention relates to the technical field of electrical engineering, and discloses a wildfire high-incidence period dynamic fire extinguishing sorting algorithm and system to achieve online dynamicfire extinguishing sorting and reduce the labor intensity of manpower for processing a large amount of data in a short time. The algorithm comprises the following steps: determining an effective fireextinguishing range, and collecting real-time fire point data and line data in the effective fire extinguishing range; calculating a wildfire threat index, and calculating a line importance index; establishing a two-dimensional data group library, selecting a two-dimensional data group of a to-be-extinguished line in the two-dimensional data group library, inputting the two-dimensional data groupof the to-be-extinguished line into the ant colony algorithm for calculation to obtain a transition probability, and taking the to-be-extinguished line corresponding to the maximum transition probability as an extinguished object; and after executing the fire extinguishing operation on the selected fire extinguishing object, updating the real-time fire point data and the line data of the to-be-extinguished line in the effective fire extinguishing range, and repeating the steps until all the to-be-extinguished lines complete the fire extinguishing operation.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a dynamic fire extinguishing sorting algorithm and a system during a high-occurrence period of wildfires. Background technique [0002] During the Spring Festival, Qingming Festival, spring plowing, and autumn harvest, due to the influence of sacrificial customs and traditional agricultural methods, there are widespread wildfires in various parts of my country. Wildfires often occur in the wild, and the distribution is relatively scattered, so it is difficult for fire departments to effectively rescue wildfires. Once the wildfire lacks effective control and spreads to the vicinity of the transmission line, it will easily cause a line trip failure, and in severe cases, it will cause damage to the equipment itself and endanger the safe operation of the power grid. Therefore, under the conditions of strong randomness of wildfires and limited fire-fighting equipment o...
