Abstract
A marine power distribution arrangement includes a turbine-driven AC generator which supplies AC power at a frequency of 240 Hz through a switchgear unit to a transformer and a first power converter by which the power is converted to a variable frequency, variable voltage AC output for ship propulsion and to a second power converter by which the AC power is converted to a fixed voltage, fixed AC frequency or DC power to supply the ship service loads. A battery backup power supply may be switched in an emergency. In another embodiment four turbine-driven AC generators and two emergency power supplies are provided to drive two propulsion shafts as well as to supply the ship service loads.
