The invention relates to a double-shaft four-machine type ship hybrid power system and a propulsion control method thereof. The hybrid power system comprises two sets of independent power devices. Theoutput end of a main push diesel engine is connected with the input end of a gearbox through a clutch; the input/output end of a propulsion motor is connected with the input/output end of the gearbox; the output end of the gearbox is connected with the input end of a full-revolving steering oar; a first group of power transmission lines of the propulsion motor are connected with a first group ofterminals of a distribution board through a propulsion motor end rectifier; a second group of terminals of the distribution board are connected with an energy storage unit; and a third group of terminals of the distribution board are connected with a second group of power transmission lines of the propulsion motor through a propulsion motor end inverter and a frequency converter in sequence. The power system is wide in power coverage range, on the one hand, power redundancy is increased, the reliability of the power system is improved, and on the other hand, multiple working modes are provided, and the requirements of various ship environments and working conditions are met.
