Embodiment Construction

[0027] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0028] figure 1 Shown is the schematic flow sheet of the on-site verification method of the polluted area distribution map of the present invention, and the on-site verification method of the polluted area distribution map includes the following steps:

[0029] (1) Select the verification area;

[0030] The principle of verification area selection is: special section lines in heavily polluted areas or areas with important crossing and crossing lines, especially UHV AC and DC, Three Gorges Outgoing Channel and special section areas of the five major DC lines.

[0031] (2) Collect on-site meteorological data, on-site pollution source data, pollution online monitoring data, and artificial on-site test data in the verification area; the on-site meteorological data includes time, 10-minute maximum wind spee...

Abstract

The present invention provides a field authentication method for a pollution area distribution map. The method comprises the following steps: (1) selecting an authentication area; (2) collecting field data of the authentication area; (3) using a frequency method to account a prevailing wind direction of the authentication area; (4) determining an impact radius of a pollution source and a pollution level of the pollution source; (5) drawing pollution distribution of the pollution source in the prevailing wind direction; (6) calculating equivalent salt and non-soluble deposit densities of field insulators, and converting to a pollution level; (7) drawing pollution distribution of the field insulators; (8) combining the pollution distribution of the pollution source with the pollution distribution of the insulators to acquire pollution distribution of the authentication area; and (9) performing comparative analysis between the pollution distribution of the authentication area and the pollution area distribution map, and authenticating accuracy of the pollution area distribution map. The present invention provides a method for authenticating the accuracy of the pollution area distribution map by using field weather data, field pollution source data, pollution online monitoring data, and artificial field test data, so that an effective guiding basis is provided for carrying out of pollution prevention of a transmission line.

Description

technical field [0001] The invention relates to the technical field of power grid transmission lines, in particular to an on-site verification method for a polluted area distribution map. Background technique [0002] The grid pollution area distribution map is the simulation and expression of the pollution distribution of the transmission line, which can truly reflect the line pollution to a certain extent, and is the basic basis for guiding the design and configuration of the external insulation of the power transmission and transformation equipment. A certain guiding role can enhance the power grid's ability to resist pollution flashover accidents, and is conducive to the development of disaster prevention and mitigation work in the power grid. Whether the distribution map of polluted areas is scientific and accurate will directly affect the development of power grid design, operation and maintenance. [0003] The existing method for verifying the accuracy of the distrib...
