    Abstract: A power distribution system is described that does not rely on a fixed frequency and which therefore allows prime movers to run at different speeds in response to load demand, typically so that fuel consumption and/or harmful exhaust emissions is/are minimised. A marine power distribution and propulsion system can include an ac busbar adapted to carry a variable-frequency ac distribution voltage. A plurality of ac generators are connected to the busbar, each having an associated prime mover such as a diesel engine, turbine etc. A power management controller is adapted to vary the rotational speed of the prime movers with reference to the electrical load on the ac busbar such that the generators provide a variable frequency output during normal operation of the power distribution system. Such operation is to be contrasted with conventional distribution systems which have a fixed frequency.

    Abstract: A power distribution system such as a marine power distribution and propulsion system. The system includes an ac busbar and a plurality of active front end power converters. Each AFE power converter includes a first active rectifier/inverter connected to the busbar and a second active rectifier/inverter connected to an electrical load such as an electric propulsion motor. Power sources are connected to the dc link of the AFE power converters and can be operated under the control of a power management controller or power management system.
