Problems solved by technology

[0008] (1) Most of the existing equipment status evaluation methods are realized by using a single status feature. However, due to the complex structure of GIS equipment and changing operating status, it is impossible to accurately evaluate the status of equipment based on a single variable
[0009] (2) Existing state assessment methods are heavily dependent on equipment failure data, but due to the accidental nature of equipment failures, the collection of failures is blind to a certain extent, and the GIS equipment state characteristic data is very small, which makes the accuracy of equipment operation status relatively low. Low
[0010] (3) GIS operating status is changeable, and the boundaries between different operating states are blurred. How to realize the online evaluation of equipment operating status needs further research

Abstract

The invention discloses a GIS equipment state evaluation method based on support vector description and K-nearest neighbor algorithm, and relates to the technical field of electrical equipment operation state evaluation; it is based on vibration signals of GIS equipment, normal state historical data of gas pressure and real-time measurement data, Combining the support vector description and the K-nearest neighbor algorithm, an evaluation method for the operating state of GIS equipment is formed; it combines the support vector description and the K-nearest neighbor algorithm based on the vibration signal of the GIS equipment, the normal state historical data of the gas pressure, and the real-time measurement data. The evaluation method of the operation state of GIS equipment is formed, and the accurate evaluation of the state of GIS equipment is realized.

Description

technical field [0001] The invention relates to the technical field of electrical equipment operating state evaluation, in particular to a GIS equipment state evaluation method based on support vector description and K nearest neighbor algorithm. Background technique [0002] At present, due to the advantages of compact structure, small footprint, reliable operation, long maintenance period, and strong anti-interference ability, GIS equipment is widely used in substation projects, especially 500kV and above EHV / UHV substations and urban 110kV and 220kV substations. With the increase in the installation of GIS equipment and the increase in the number of years in operation, failures of GIS equipment in operation often occur. The sealing of GIS equipment helps to isolate external interference, but it also brings difficulties to equipment fault detection and diagnosis. When a fault occurs inside the GIS device, the operation and maintenance personnel cannot intuitively and timel...
