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 construction method for a microtopographical micrometeorological element field. The method comprises the steps of step 1: selecting meteorological source data; step 2: determining an interpolation scheme; step 3: constructing the microtopographical micrometeorological element field; step 4: verifying the microtopographical micrometeorological element field: verifying whether a statistic model of the microtopographical micrometeorological element field is an optimal model or not, if yes, performing the step 5, or if not, returning the step 3 and adjusting an initially determined spline frequency until the statistic model of the microtopographical micrometeorological element field is the optimal model; and step 5: drawing an ArcGIS graph. According to the construction method, the management level of power grid safety can be improved, the coping capacity of resistance to natural disasters can be enhanced, and research achievements 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...
