The invention provides an offshore fixed platform for electric propulsion ship replenishment, which comprises a first direct-current busbar, a first DC/DC converter and a second direct-current busbar, the first DC/DC converter is connected with the first direct-current busbar and the second direct-current busbar, the first direct-current busbar can gather the electric energy generated by an internal combustion engine and the electric energy of a new energy power generation system, and the second direct-current busbar can gather the electric energy generated by an internal combustion engine and the electric energy of a new energy power generation system. The first DC/AC converter and the ship power supply assembly can utilize the electric energy on the first direct current busbar to provide electric power supply for the electric propulsion ship; on and off of a power switching device in a first AC/DC converter are controlled based on an SVPWM control algorithm according to a sampling voltage of a first DC busbar, a sampling current of a generator, a target voltage of the first DC busbar and a target current of the generator, so that the stability of the voltage on the first DC busbar can be maintained, and the stability of the voltage on the first DC busbar is improved. And power supply is stably and reliably provided for the electric propulsion ship.
