The invention aims to provide an ammonia-electricity hybrid power system of an integrated power turbine single-shaft double-motor ship. The ammonia-electricity hybrid power system comprises an ammoniafuel engine, a reversible motor, a diesel generator set, a storage battery, a capacitor, a fuel cell, a propeller, a liquid ammonia storage and supply device, a power transformation device, a ship power grid, a ship load, a whole ship cooling system and a waste heat system. The ammonia fuel engine is connected with the first reversible motor and the second reversible motor to drive the variable-pitch propeller, and the third reversible motor is directly connected with the fixed-pitch propeller. The diesel generator set is connected with the storage battery, the super capacitor and the fuel cell through the power transformation device and the ship power grid; the waste heat system utilizes a motor, a storage battery, a fuel cell and engine waste gas for combined power generation. Hybrid propulsion of the ammonia fuel engine and the motor and coordinated power supply of the diesel generator set and the energy storage unit can be achieved. Meanwhile, multi-stage utilization of cold energy of the energy storage unit and the engine is achieved, and the waste heat system can achieve multi-stage heat energy utilization.
