Embodiment Construction

[0024] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0025] A micro-meteorological observation point layout method suitable for wind disaster monitoring of transmission lines with complex terrain, comprising the following steps:

[0026] 1. Layout plan

[0027] In order to achieve scientific and reasonable early warning of wind field distribution in high-precision complex terrain areas, first consult the routine monitoring data of meteorological stations in the area, and obtain the latest global analysis data (Final Operational Global) provided by the National Centers for Environmental Prediction (NCEP). Analysis (FNL for short, this data has higher temporal and spatial resolution than the reanalysis data) is used as the initial field of the numerical model simulation, using the WRF model to simulate the distribution of the near-surface wind field in the study area, and output the ...

Abstract

The invention relates to a micrometeorological observation distribution point method for wind disaster monitoring suitable for complex terrain power transmission lines. Based on the statistical analysis of historical disaster data, the method proposes a rule-based space superposition method, spatial analysis methods of wind field simulation and a geographic information system at different heightsin a mesoscale weather forecasting mode are integrated, the selection of a microclimate observation station for power transmission lines in a region is realized, the distribution point observation andthe model simulation are adopted, the distribution situation of the wind field at different heights is grasped in real time and dynamically, the distribution situation of wind disasters to a tower station of power transmission lines is monitored, technical guarantee for the safe operation of power is provided, and a complete set of indoor comprehensive simulation analysis and the technical process of point selection combined with field practical reconnaissance is formed. The problem of the power failure of the tower station after the power transmission lines in the region suffers from the wind disaster is impossible to predict. The scheme is novel, the representation of the distribution point results is strong, technical support for the deployment of the strong wind meteorological disaster monitoring network of the power transmission lines is provided, and popularization and implementation are easy.

Description

technical field [0001] The invention relates to the field of micro-meteorological observation. Specifically, it refers to a micro-meteorological observation point layout method suitable for wind disaster monitoring of transmission lines with complex terrain. This method proposes a spatial superposition based on complex terrain tower stations, which can quickly select the most representative transmission line tower stations under complex terrain conditions as wind field monitoring points from many transmission line tower stations, which is convenient for micro-meteorological Observation instruments are installed to provide early warning for the safe operation of transmission lines. Background technique [0002] The wind field of mountainous terrain is different from the wind field of flat landform conditions. The complex terrain of mountainous areas will significantly change the distribution of near-surface flow wind speed in the vertical direction and the turbulence struc...
