Simulation Scheme

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.

In this paper, the simulation analysis on partial discharge (PD) signals produced by multiple insulation defects in gas insulated substation (GIS) has been researched by the simulation software of electromagnetic field (XFDTD). The theoretical analysis and simulation results show that the single partial discharge signal is the linear convolution of the partial discharge current signal and its corresponding impact response in GIS. The mixed partial discharge signals are the linear mixtures of every partial discharge signal.
