| Abstract: | The characteristics of 1000 kV AC compact transmission line are discussed,and the calculating results of secondary arc current and recovery voltage of 1000 kV AC compact transmission line using EMTP under different conditions such as the different length of the transmission line,the compensation factor,transposition,are presented.Simulation results show that the neutral reactor for HV shunt reactors can effectively limit the second arc current and recovery voltage,and the principle of selection of neutral r... |
