Problems solved by technology

However, the traditional forest fire danger level early warning method only considers the meteorological forecast of fire danger, and the model parameters are all meteorological factors, without considering the actual situation of the power grid transmission line, so it does not meet the needs of early warning

Embodiment 1

[0047](1) Formulate the early warning level standard for the transmission line of the power grid. The mountain fire warning levels of transmission lines in the entrusted area are divided into five levels according to the principle of heavy to light, with red, orange, yellow, blue and none, which are:

[0048] (1.1), the red warning is the first-level transmission line mountain fire warning. This level of early warning means that the density of fire points monitored by entrusted regional satellites reaches 15 / 10,000 square kilometers or more, or the number of fire points alarms within 3 kilometers on both sides of the entrusted regional power transmission line reaches 50 or more;

[0049] (1.2), the orange warning is the mountain fire warning of the secondary transmission line. This level of early warning means that the density of fire points monitored by entrusted regional satellites reaches 10-15 per 10,000 square kilometers, or the number of fire points alarmed within 3 kil...

Embodiment 2

[0080] Steps (1)~(5) are the same as in Example 1;

[0081] (6) Determine the early warning level of the transmission line mountain fire on the forecast day of the entrusted area. There are different transmission line mountain fire warning levels in the commissioned area on the commissioned forecast day, and the transmission line mountain fire warning level with the largest warning area is taken as the transmission line mountain fire warning level on the commissioned forecast day of the commissioned area;

[0082] Step (7) is the same as in Example 1.

Abstract

The invention provides a method for early warning power grid transmission line mountain fire intelligently in a graded mode. The method comprises the following steps of 1, making early-warning standards for power grid transmission line mountain fire, 2, judging early-warning grades of historical power transmission line mountain fire, 3, deciding all grades of early-warning weather thresholds, 4, deciding a weather early-warning grade of a forecasting day, 5, judging the mountain fire early-warning grade of the day before the forecasting day, 6, deciding the power transmission line mountain fire early-warning grade of a delegated zone in the forecasting day, and 7, outputting early-warning results. The method can finally decide the power transmission line mountain fire early-warning grades by judging early-warning grades of all weather elements and current situations of satellite monitoring fire points. The method can meet actual situations well, is easy to achieve, is high in forecasting accuracy, can optimize resource distribution, improves prevention and cure efficiency, reduces casualty loss and maintains safety of power grids.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to an intelligent level early warning method for a mountain fire in a transmission line of a power grid. Background technique [0002] Southern provinces are prone to wildfire disasters in the event of continuous drought, especially during spring plowing and Qingming fire seasons, when large-scale wildfires even broke out. The pollution or air discharge near the power grid transmission lines also caused tripping and power outages. In 2013, it reached 30 Many times, it has become a major threat to the safe and stable operation of UHV lines and large power grids, seriously affecting people's daily life and industrial and agricultural production. Therefore, the early warning of mountain fire levels on transmission lines can be targeted to deploy prevention and control measures in advance to reduce losses caused by disasters. However, the traditional early wa...
