The invention discloses a power management method for an aviation series hybrid electric propulsion system. The aviation series-connection hybrid electric propulsion system comprises an aero-engine, a generator, a battery, a motor, a transmission and a propeller, efficiency is introduced into the aviation series-connection hybrid electric propulsion system as an evaluation index for the first time, and a system power management scheme is optimized in combination with the rotating speed of a variable power turbine. Compared with the prior art, the efficiency of the aero-engine can be improved, the loss is reduced, the optimal scheme of expected power distribution of the aero-engine and the battery under the determined voyage is obtained, and the performance of the hybrid electric propulsion aircraft is improved.
