摘要： A high voltage direct current (HVDC) power transmission system includes a cable fault ride-through system. The cable fault ride-through system is configured to ensure the HVDC power transmission system remains operational via an earth path between the power source end and the load end during a transmission cable fault, even in the absence of a neutral bus and/or dc circuit breakers.

摘要： A modular substation (10) for subsea applications includes a plurality of modular DC/AC converters (32) configured for converting DC electrical power transmitted along a DC transmission link (24) into AC electrical power for supplying to a plurality of subsea loads (56). The plurality of modular DC/AC converters (32) is configured to couple in series to the DC transmission link (24) and couple in parallel to an AC distribution network (52). At least a first modular DC/AC converter (32) is configured to be selectively electrically and mechanically disconnected from the DC transmission link (24) and the AC distribution network (52) to facilitate maintenance of the first modular DC/AC converters (32) while the AC distribution network (52) continues to supply AC electrical power to at least one of the plurality of subsea loads (56). The modular substation (10) also comprises protection and bypass circuits (26) intended to isolate faulty DC/AC converters (32) and to facilitate safe maintenance and repair.

The power circuit also includes a first DC to DC converter coupled between the first DC bus and the second DC bus, wherein the first DC to DC converter is configured for bidirectional power flow and an AC to DC converter coupled between the AC bus and the first DC bus. The first DC bus of at least one power circuit is coupled to the second DC bus of at least another power circuit with a second DC to DC converter. The system also includes a controller configured to control the operation of the first DC to DC converter, second DC to DC converter and the AC to DC converter for regulating the first and second DC voltages.

摘要： A power transmission system is provided. The power transmission system includes at least one power substation for receiving power from a power source, and a Direct Current (DC) cable for transferring the power from the power source to the power substation. The DC cable includes a plurality of segments individually or in combination forming a path to route the power to the power substation. The system further includes at least one segment switch unit electrically coupled to each segment. At least one of the segment switch units includes a shorting switch element for providing a short circuit path to prevent the power from the power source to be routed to a respective segment in response to a shorting command, and a disconnect switch element for disconnecting the respective segment in response to a disconnect command.
