Abstract: A bipole power transmission network includes a first upstream power converter which has a first DC terminal that is connected with a first transmission conduit which extends, in-use, to a first downstream power converter. The first upstream power converter has a second DC terminal that is connected with a return conduit which extends, in-use, to the first downstream power converter and a second downstream power converter. The first upstream power converter has at least one first AC terminal electrically connected with a first AC power source. The bipole power transmission network includes a second upstream power converter which has a third DC terminal that is connected with the return conduit, and a fourth DC terminal which is connected with a second transmission conduit that extends, in-use, to the second downstream power converter, and at least one second AC terminal electrically connected with a second AC power source.

Abstract: A bipole power transmission scheme typically includes a first converter station that is positioned remote from a second converter station, along with first and second transmission conduits which interconnect the first and second converter stations to permit the transmission of power between the first and second converter stations. The first converter station has first and second power converters, with the first power converter including a first DC terminal that is connected with the first transmission conduit, at least one AC terminal which is connected with a first AC network, and a second DC terminal that is interconnected with a third DC terminal of the second power converter by a first interconnection which defines a first neutral area. The second power converter additionally includes a fourth DC terminal that is connected with the second transmission conduit and at least one AC terminal which is connected with a second AC network.
