Abstract

PURPOSE:To enable to drive a propulsion propeller at a low speed even when a propulsion main engine is defective by releasing the coupling of the main engine to an axial generator when the main engine becomes defective and driving an axial generator by the electric power of a marine auxiliary generator. CONSTITUTION:When a main engine 1 is normal, power is supplied to a marine AC bus through a power converter 30 mainly from an axial generator 3 through a converter 4 and an inverter 6. When the engine 1 becomes defective, a marine auxiliary generator 12 is first started to supply power to the marine AC bus 10. Then, coupling means 31 provided between the engine 1 and the generator 3 is disconnected. Thereafter, the AC power of the bus 10 is supplied through the converter 30 to the generator 3, thereby driving the propulsion propeller 2.
