| 英文摘要: |
| The field impulse voltage test circuit of 550 kV GIS can simulate the GIS insulation characteristics under the overvoltage and verify the actual effect of the VFTO suppression technique, by the VFTO generator outputs a transient overvoltage to the GIS. the paper proposed a simulation modeling method of test loop by EMTP software. Compared with the experimental data, the results showed that simulation waveform was very close with experimental data on the maximum voltage and peak time, and results verified that the model was in line with actual situation, and had the engineering application value. |
