PCT No. PCT/SE98/00995 Sec. 371 Date Dec. 9, 1999 Sec. 102(e) Date Dec. 9, 1999 PCT Filed May 27, 1998 PCT Pub. No. WO98/57409 PCT Pub. Date Dec. 17, 1998A plant for transmitting electric power having a direct voltage network (18) for High Voltage Direct Current and at least one pole conductor interconnecting two stations (21, 22). In each station (21, 22), a bidirectionally controlled thyristor (BCT) conducts current in both directions as rectifying semiconductor components. A control unit (35) is adapted to control the current direction through the bidirectionally controlled thyristors so as to choose that the earth electrode (33, 34) of each station is always either anode or cathode. |
