Research on PD Type Identification Ability Test Method of GIS UHF On-Line Monitoring Equipment Based on PRPD Map Simulation

GIS equipment has now become the key equipment of power system, but in the process of its operation, internal discharge faults often occur due to metal particles, surface contamination and other reasons. The installation of GIS UHF partial discharge on-line detection equipment plays an important role in the early warning of GIS partial discharge. At present, the UHF on-line monitoring equipment still has insufficient ability to identify the type of partial discharge. There are still some UHF partial discharge on-line monitoring equipment used in UHV stations that cannot accurately identify the type of discharge, and there is currently no effective test method for the ability to identify the type of partial discharge of UHF on-line monitoring equipment. Therefore, it is of great significance to carry out the research on the test method of partial discharge type recognition ability of UHF on-line monitoring equipment.
