The invention discloses a current control method for a double-winding induction generator direct-current parallel system, relates to the technical field of power generation and power distribution, and is suitable for controlling a multi-electric-propulsion aircraft power supply system. According to the method, a current control method is improved, a reference current value is not actively given any more, a direct-current voltage reference value of a main generator is determined according to the droop characteristic of the generator, and a direct-current voltage reference value of a slave generator is obtained through the direct-current voltage reference value of the main generator and ideal output power needed by the slave generator; current deviation values of actual output currents of the master generator and the slave generator and respective reference currents are transmitted to voltage signals and compared with corresponding direct current voltage reference values, obtained voltage deviation values are t
