A converter station, for a bipole power transmission scheme, includes a first voltage source converter and a second source converter. Each converters have a first terminal as transmission conduit and a second terminal as a return conduit. The second terminal of the return conduit of the first converter is electrically connected to the first terminal of the transmission conduit of the second converter as being a same terminal. Both voltage source converters also includes at least one converter limb which extends between the first and second terminals of each converters. The or each converter limb includes first and second limb portions that are separated by a corresponding first and second AC terminal which is for connection to a respective phase of a first or second AC network.

Converter stations

A bipole power transmission scheme includes a first converter station positioned in-use remote from a second converter station, and first and second transmission conduits to in-use interconnect the first converter station with the second converter station and thereby permit the first converter station to transmit power to the second converter station. The first converter station includes a first power converter, a second power converter, and a converter station controller which is programmed to selectively transition the bipole power transmission scheme into an asymmetrical monopole configuration, while maintaining the transfer of power from both the first and second power sources.

Bipole power transmission schemes

A bipole power transmission scheme with two independent converts, two power feed and one return conduit. During operation of the bipole power transmission scheme under abnormal conditions, when a return conduit is faulty and unable to provide a return current path, each converter controller is programmed to monitor the first power feed in the first transmission conduit and the second power feed in the second transmission conduit and, if the first power feed in the first transmission conduit and the second power feed in the second transmission conduit differ from one another, at least one converter controller modifies the power infeed from its corresponding power source to reduce the difference between the first power feed and the second power feed.
