POWER DISTRIBUTION SYSTEM FOR OFF-SHORE NATURAL RESOURCE PLATFORMS

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.

1. An off-shore medium voltage direct current (MVDC) power distribution system for supplying power to off-shore equipment, the MVDC power distribution system comprising:
an off-shore MVDC power bus comprising a plurality of power bus segments, wherein each power bus segment is electrically connected to at least one other power bus segment via a circuit breaker, and wherein (i) at least one power bus segment of the plurality of power bus segments is electrically coupled to an off-shore renewable energy source configured to supply power to the off-shore MVDC power bus, wherein the renewable energy source includes an off-shore energy storage to reduce variance of power delivery from the renewable energy source, and (ii) at least one power bus segment of the plurality of power bus segments is electrically coupled to a local power distribution system of an off-shore drilling platform, wherein the local power distribution system is configured to receive power from the off-shore MVDC power bus and supply power to a local load of the drilling platform.
