At present, the Variable-Speed Variable-Frequency (VSVF) synchronous generator, which is widely used in the aircraft variable-frequency AC power system, is used in the architecture design for the electric propulsion aircraft power system. In existing research and practice, the VSVF synchronous generator is considered to only work in the non-parallel state during normal operation. This structure of independent channels limits the power integration of the system. Taking advantage of the asynchronous characteristics of the DWIG and its control winding’s AC-DC-AC topology, the limitation that the generation system of electric propulsion aircraft cannot operate in parallel due to the VSVF synchronous generator can be overcome. This article proposes a coordinated control scheme for parallel operation based on power flow control, which is applied to the DWIG to realize synchronization of frequency and phase which is independent of the prime mover. Theory and experiments show that the proposed parallel generation system has flexible control performance and great self-balance in output power. The proposed system structure and control method make the parallel power system based on the DWIG a feasible architecture for electric propulsion aircraft.
