The invention discloses a diesel-electric hybrid power ship propulsion system and an energy management method of the diesel-electric hybrid power ship propulsion system. The diesel-electric hybrid power ship propulsion system comprises a main diesel engine, a propeller, an electricity generating electric motor, a gearbox, an energy storage device and an energy management module, wherein a charging inversion all-in-one machine is arranged between the electricity generating electric motor and the energy storage device; and the energy storage device comprises a super capacitor, a storage battery and a power distribution unit. The energy management method comprises the steps of obtaining the required power P and the energy storage device state{SC, BA} and selecting the operation mode according to an operation mode judging table in accordance with the energy storage device state{SC, BA}. The diesel-electric hybrid power ship propulsion system and the energy management method of the diesel-electric hybrid power ship propulsion system have the advantages that the ship power demand is softened; the proper propulsion system operation mode is selected according to the demand power and the energy storage device state, so that the main diesel engine works in the optimum efficiency interval to the greatest degree; the fuel economy is good; and the energy utilization rate is high.
