Abstract :
Based on a hydro-energy storage station, the very fast transient over-voltage in GIS is calculated and simulated using the FORTRAN language and Matlab program. The node with the maximum of the VFTO is found. The suppression effect of cable and SF6 busbar is discussed, and the influence the shunted capacitor is analyzed in the paper. It is indicated that the VFTO peak-values may be restricted by increasing the length of the cable and the SF6 busbar properly, and frequency may be lowered. In addition, and the VFTO peak magnitude may be varied with the capacity of the shunted capacitor.
