Embodiment Construction

[0016] Below in conjunction with specific embodiment the present invention is described in further detail:

[0017] The present invention combines remote sensing terrain information with a method for early warning of wind damage in a medium and micro scale power grid, which includes the following steps:

[0018] Step 1: In the numerical weather prediction model system, set triple grid level nesting for the power grid waiting for wind damage warning area in the numerical weather prediction model system;

[0019] Step 2: In the numerical weather prediction model system, set the wind speed model integration step size of the outermost grid in step 1 to the set value A, set the wind speed model integration time to the set value B, and output the wind speed model integration every hour result;

[0020] Step 3: Obtain the meteorological data information of the wind damage warning area of ​​the power grid in the numerical weather prediction model system;

[0021] Step 4: In the nume...

Abstract

The present invention relates to a middle micro-scale power grid wind damage early warning method through combination of remote sensing landform information. The method takes a forecast field formed by WRF as an initial condition, employs a CALMET meteorological model to perform refinement diagnosis of the wind field and downscaling calculation, and leads in remote sensing landform information data with higher resolution to obtain the forecast with higher resolution.

Description

technical field [0001] The invention relates to the technical field of wind damage early warning for power grids, in particular to a method for early warning of wind damage for medium and micro scale power grids combined with remote sensing terrain information. Background technique [0002] my country's power transmission network covers a wide area and is affected by various climatic conditions and natural disasters. In addition to lightning and snowfall, the safe operation of the power grid is also affected by strong winds and dust. Especially in the northwestern region of my country, which is located in middle and high latitudes and has little surface coverage, it is prone to strong wind and dust weather. The extremely strong wind and sand and dust pose a serious threat to the safe operation of the power grid. Strong winds can cause accidents such as wind deflection tripping of lines, damage of insulators, broken strands of ground wires, and damage of towers. The accompa...
