Embodiment 1

[0021] (1) From the weather forecast in the forecast area, collect the real-time ground meteorological data in the forecast area of ​​the day and the forecast weather data in the forecast day, including industrial and agricultural fire data, precipitation data, data on the number of days without rain, temperature data, and humidity data , dew point temperature data;

[0022] (2.1), according to the industrial and agricultural fire data collected in step (1), use conventional methods to form the high-incidence period of industrial and agricultural activities in the forecast area. Judging whether the forecast date is within the period of high incidence of fire use in these industrial and agricultural activities, the judgment results show that the forecast day is in the period of high incidence of fire use in industrial and agricultural activities, and make a judgment that the conditions for industrial and agricultural fire use are established;

[0023] (2.2), according to the pr...

Embodiment 2

[0030] Step (1) is with embodiment 1;

[0031] (2.1), according to the industrial and agricultural fire data collected in step (1), use conventional methods to form the high-incidence period of industrial and agricultural activities in the forecast area. Judging whether the forecast date is within the period of high incidence of fire use in industrial and agricultural activities, the judgment result shows that the forecast day is not in the period of high incidence of fire use in industrial and agricultural activities, and making a judgment that the conditions for industrial and agricultural fire use are not established;

[0032] (2.2), according to the precipitation data that step (1) collects, judge whether there is precipitation in the forecast day of forecast area, judged result shows that the forecast day rainfall of forecast area is not zero, makes the judgment that precipitation condition is not established;

[0033] (2.3), according to the number of days without rain d...

Abstract

The invention provides an electric transmission line forest fire forecasting method, which includes the following steps: (1), collecting meteorological data; (2.1), analyzing fire using conditions in industry and agriculture; (2.2), analyzing precipitation conditions; (2.3) analyzing rainless days conditions; (2.4), analyzing temperature conditions; (2.5), analyzing humidity conditions; (3), drawing forecasting conclusion; (4), issuing forecasting conclusion. The electric transmission line forest fire forecasting method has the following advantages that:(1),the method can perform electric transmission line forest fire forecasting for power grid forest fire area of next two days; (2), the electric transmission line forest fire forecasting method is high in practical application and convenient to operate; (3), the accuracy rate of forecasting electric transmission line forest fire is high; (4), the method has a guiding significance for electric transmission line operating staffs to draw up a forest fire prevention and control measurement, and has an important effect on maintaining the safety and stability of the power grid and reducing disaster loss.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a method for forecasting mountain fires in power transmission lines. Background technique [0002] Affected by meteorological factors such as drought and lack of rain, forest fires frequently occur in southern China, and transmission lines span mountain fire-prone areas and are spread all over the mountains. Once a mountain fire occurs, the pollution generated or the air discharge caused by it will cause the transmission line to trip. In February 2009 alone, there were as many as 12 line trips in Hunan Power Grid due to wildfires, accounting for 64.3% of the total line trips during this period, and 8 of them occurred between February 11 and 12. In China, the number of mountain fire trips is so high and the intensity is so high, it is really rare. After the transmission line trips due to wildfire, due to the influence of insulator pollution, it is diffi...
