The Simulation and Realization Methods of Partial Discharge Signal in Gas Insulated Substation

Abstract:

On the basis of the analysis of simulating the partial discharge (PD) signals in Gas Insulated Substation (GIS), this paper focuses on discussing the common simulation and realization methods of simulating the partial discharge signals in mechanical and electrical equipments. The characteristics of PD signals and the typical insulation defects of GIS are reviewed. Different simulation methods to simulate the PD signals are considered. Two implementation schemes of simulating the discharge pulse are analyzed and compared with each other. Through the analysis, we find out that the electronic technology will be the most hopeful way to achieve the desired goals, which are to simulate those PD signals. This paper provides a simulation scheme of simulating PD signals, which can be described as multi-stage paralleling of MARX circuit and can provide a reliable reference for engineering practice.
