Embodiment Construction

[0027] The construction of micro-topographic and micro-meteorological element fields involves monthly average temperature, air pressure, relative humidity and wind speed. The construction of the so-called micro-topographic and micro-meteorological element field refers to interpolating it into the required fine element field through a certain interpolation scheme based on the relatively sparse observations at present, so as to obtain the refined grid point element field distribution. The formed grid point element field is arranged in the order of equal longitude and latitude, and the refined grid point spatial resolution can be 0.01°, 0.05° or 0.1°, etc.

[0028] figure 1 Shown is a method for constructing a micro-topography and micro-meteorological element field of the present invention, including selecting meteorological source data, determining an interpolation scheme, constructing a micro-topographic and micro-meteorological element field, verifying a micro-topographic and ...

Abstract

The invention discloses a method for constructing a micro-topography and micro-meteorological element field, comprising: step 1: selecting meteorological source data; step 2: determining an interpolation scheme; step 3: constructing a micro-topography and micro-meteorological element field; step 4: verifying the micro-topography Micro-meteorological element field; verifying the micro-topographic micro-meteorological element field is to verify whether the statistical model of the micro-topographic micro-meteorological element field is the best model. If yes, go to step 5; if not, go back to step 3, and adjust the initial spline times until the statistical model of the micro-topography and micro-meteorological element field is the best model; step 5: draw the ArcGIS map. The construction method of the present invention will improve the management level of power grid security, improve the ability to resist natural disasters, and the research results will also ensure the safety, stability and daily operation of the power grid.

Description

technical field [0001] The invention relates to the field of micro-topography and micro-meteorology of power transmission lines, in particular to a method for constructing micro-topography and micro-meteorology element fields. Background technique [0002] Mainly based on meteorological observation data for many years, by constructing micro-topography and micro-meteorological element fields, the main characteristics of transmission line meteorological disasters in micro-topography and micro-meteorology areas are obtained, and the occurrence and development laws of transmission line meteorological disasters are revealed. Statistical Modeling Between Meteorology. [0003] With the increasing intensity of power grid construction, the distribution of transmission lines is becoming more and more dense. Some transmission lines are even laid in high mountains, and the probability of meteorological disasters is greatly increased. The requirements for micro-topography and micro-meteo...
