Systems and methods for providing an uninterruptible power supply to a ship-service bus of a marine vessel

摘要

A marine vessel power and propulsion system that provides a vessel-wide uninterruptible power supply is described. The power and propulsion system includes a propulsion system including a prime mover coupled to a motor/generator and a propulsion device. The motor/generator is configured to be driven by the prime mover and to generate alternating current (AC) electric power. The power and propulsion system also includes a ship-service electrical system including a generator set and a ship-service bus. The generator set is configured to generate ship-service electric power for distribution over the ship-service bus. The power and propulsion system also includes a bi-directional converter configured to couple the propulsion system to the ship-service electrical system and to convert AC electric power generated by the propulsion system to ship-service electric power for distribution over the ship-service electrical system.
