WebGIS based local discharge data management method for gas insulated switchgear

Abstract

The invention discloses a WebGIS based local discharge data management method for a gas insulated switchgear. The method is characterized by comprising the following steps of step SS1, establishing a WebGIS platform; step SS2, acquiring local discharge spatial position coordinates; step SS3, performing local discharge spatial autocorrelation analysis; step SS4, drawing a local discharge intensity spatial distribution thematic map; and step SS5, performing local discharge data query management. The method has the beneficial effects that (1) a spatial position characteristic of a local discharge phenomenon is fully considered, the WebGIS platform is established based on the consideration, the local discharge data is displayed based on the map, the graphic and visual local data query management can be realized, an original attribute relationship based general query management method is changed, and the data management efficiency is improved; and (2) after the local discharge data is endowed with a spatial position attribute, a local part can be subjected to spatial analysis by virtue of a geoanalysis method, a spatial distribution law of the local discharge phenomenon can be mined, and a support can be provided for comprehensively diagnosing a state of an electric power device.

Description

technical field [0001] The invention relates to a method for managing partial discharge data of a gas-insulated combined electrical appliance based on WebGIS, and belongs to the technical field of distribution networks. Background technique [0002] Geographic Information System (GIS, Geographic Information System) is a comprehensive subject, combining geography and cartography, remote sensing and computer science, has been widely used in different fields, is used to input, store, query, analyze and display geographic data With the development of GIS, GIS is also called "Geographic Information Science". In recent years, GIS is also called "Geographic Information Service". GIS is a computer-based tool that enables the analysis and processing of spatial information (in short, the mapping and analysis of phenomena that exist and occur on Earth). GIS technology integrates the unique visual effects and geographic analysis functions of maps with general database operations (such ...

AI Technical Summary

Problems solved by technology

[0008] The traditional recording method of partial discharge position information tends to use relative position to describe, such as XX part of XX transformer. This recording method is relatively simple and can meet the general application requirements, but the scalability is poor, and there is no use of partial discharge in essence. The location attribute cannot intuitively indicate the location where the partial discharge occurs, nor can it analyze the data from the perspective of spatial distribution, which is not conducive to the management and maintenance of a large amount of partial discharge data
