GIS supersonic partial discharge live-line detection simulation implementation method

Abstract

The invention relates to the field of power system simulation training, and especially relates to a GIS supersonic partial discharge live-line detection simulation implementation method. The method comprises the following steps: (1), collecting a supersonic partial discharge typical defect map and feature data; (2), analyzing the envelope features of a simulation map; (3), simulating and generating a discharge spectrum map: generating a test spectrum on a simulation tester through analyzing various types of defect spectrums and giving consideration to the time domain and frequency domain features; (4), simulating the consistency of the hardware equipment for partial discharge detection with the reality; (5), simulating the consistency of the whole testing process with an actual process. The method achieves a typical defect signal of supersonic partial discharge via the principle of statistics through the digital simulation, achieves the manual control, and brings convenience to a learner for mastering the defect position and judging the type of a defect.

Description

technical field [0001] In the field of power system simulation training, it particularly relates to a GIS ultrasonic partial discharge live detection simulation implementation method. Background technique [0002] SF6 gas-insulated combined electrical equipment (GIS) is widely used in power systems because of its low failure and maintenance-free characteristics. However, GIS has the particularity of being fully enclosed, so that except for a few test items such as micro-water detection, most of the current routine tests of high-voltage electrical equipment cannot be used. GIS has been almost in a state of no maintenance for a long time. It is not easy to troubleshoot the defects that appear inside the GIS equipment. With the increase of the GIS voltage level and the shrinkage of the volume, the electric field inside the GIS is getting higher and higher. The main insulating media inside the GIS are SF6 gas and epoxy insulating components. When there is a defect in the insu...
