Embodiment Construction

[0028] The transmission line is laid by the power department, including line towers, wires, insulators, tower foundations, and grounding devices.

[0029] Such as figure 1 As shown, a method for calculating the standard ice thickness of transmission lines based on weather stations, the method includes:

[0030] Step 1: Accumulate relevant data on icing.

[0031] Icing-related data include icing data, meteorological elements of the first observing station and meteorological elements of the second observing station.

[0032] The icing data of the first observation station include the ice thickness, weight and wire radius of the transmission lines observed by the first observation station.

[0033] Further, the meteorological elements of the first observation station include air temperature, humidity, water vapor pressure, precipitation, wind direction and speed, sunshine, rime, and rime observed by the first observation station.

[0034] Further, the ice-related data also inc...

Abstract

The invention discloses a transmission line standard ice thickness calculation method based on a meteorological station. The method includes the steps that 1, ice-coverage-related materials are accumulated; 2, ice thickness schemes are compared; 3, a standard ice thickness model of a first observation station is determined; 4, data quality of meteorological elements of a second observation station is controlled; 5, whether the second observation station is covered with ice or not is judged; if the second observation station is covered with ice, step 6 is executed; if the second observation station is not covered with ice, the process is ended; 6, the standard ice thickness of the second observation station is calculated. By means of the transmission line standard ice thickness calculation method, blindness of power grid design can be reduced, and stability and effectiveness of power grid operation are enhanced.

Description

technical field [0001] The invention relates to the field of icing on power transmission lines, in particular to a method for calculating the standard ice thickness of power transmission lines based on a weather station. Background technique [0002] my country's weather, climate and geographical environment are complex, and meteorological disasters in power grids often occur. Affected by micro-topography and micro-meteorological conditions, icing disasters have the most extensive impact on power grid meteorological disasters, and icing disasters have become one of the important factors that seriously affect the safe operation of power grids. With the increase of my country's economic construction and social strength, the construction of power grid projects has shown a momentum of rapid development. However, there are few ice-covered meteorological observation stations in my country, and the distribution is limited. , Operation management brings difficulties. Contents of t...
