Abstract:
This article aims to study the transmission characteristics of the very fast transient over-voltage(VFTO)generated by the breakdown of the insulating gas when the isolating switch in a gas insulated substation(GIS)is opened and closed. In this paper,the transmission line system is divided into inner and outer loops,and the telegraph equation is solved by the finite difference method respectively,and the transient response of the transmission line port is obtained. The calculation results are highly consistent with the CST CABLE STUDIO simulation results,which proves the effectiveness of the proposed model and calculation method. The proposed method is of great significance to the analysis of the crosstalk and attenuation characteristics of the primary and secondary transmission cables.
