| Abstract: | After fault occurred on ±800 kV DC wall bushing of pole II in Jinhua converter station, the grounding line also has breakage fault. By using ATP-EMTP, response of grounding electrode conductor and shielding wire is simulated with 5 970 A and 5 215 A fault current. The results are compared with recorded fault waveform. According to calculation results, the breakage reasons of insulator string and shielding wire are analyzed in detail. The recommended grounding line insulation configuration is also introduced. |
