Abstract

The invention discloses a partial discharge location method, device and system. The partial discharge location method includes: collecting the partial discharge signal of the partial discharge source induced by the UHF antenna array; determining the position measurement value according to the partial discharge signal; and performing error compensation on the position measurement value according to the preset error compensation model to obtain the position correction value, where the location measurement is the measurement of the location of the partial discharge source. The present invention solves the problem of relatively large positioning errors for partial discharges in the positioning method in the related art.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a partial discharge location method, device and system. Background technique [0002] Partial discharge (Partial Discharge) is a manifestation of the deterioration of the insulation performance of power equipment, and it is also the cause of further deterioration of the insulation performance of power equipment. In order to detect insulation defects of equipment in time and prevent insulation breakdown faults, it is necessary to monitor and locate partial discharge signals. Positioning the partial discharge position through the positioning system can find the partial discharge position in time. After the partial discharge position is determined, the electric equipment can be repaired to prevent the occurrence of major failures. The positioning system can use the existing positioning methods, for example, Ultra High Frequency (UHF) positioning method, the use of ultra-high frequency el...
