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. The controller is further configured to provide power to the second DC bus from the at least one AC to DC converter during a first operating state and from the first DC to DC converter during a second operating state.

摘要： A method for operating a plurality of wind energy installations configured for supplying electric power to an electrical supply system, that each have an aerodynamic rotor with rotor blades and an electrical generator and also operating equipment, is disclosed. The wind energy installations are operated while they are not connected to the electrical supply system, where at least one of the wind energy installations produces electric power and inputs the electric power into a local DC voltage system that connects the wind energy installations if the at least one of the wind energy installations currently produces more power than needed for supplying its own operating equipment. Additionally or alternatively, the operating equipment is supplied totally or in part with power from the local DC voltage system if the at least one of the wind energy installations currently produces less power than needed for supplying its operating equipment.

摘要： A power distribution system for off-shore natural resource platforms includes an off-shore medium voltage direct current (MVDC) power bus. The MVDC power bus includes multiple power bus segments, each of which may be connected to one or more other power bus segments via a corresponding circuit breaker. Each power bus segment may also be electrically coupled to an off-shore renewable energy source, such as a wind farm, and/or an off-shore drilling platform. The off-shore drilling platforms may include local power distribution systems electrically connected to a corresponding power bus segment via a circuit breaker to receive power from the MVDC power bus and supply power to local equipment of the off-shore drilling platform.
