| Abstract: | Combined with the recent reconstruction project of 220 kV line production,by using the adjacent line of OPGW fiber spare core to form temporary circuitous channel,the paper proposed a rational reconfiguration for two 220 kV line protection without fiber channel.The optical fiber current differential protection and the carrier channel high frequency protection were applied as the configuration scheme.After technical improvement,two sets of optical fiber current differential protection were used,which may rea... |
