The invention discloses a tandem type aviation hybrid power system starting control method considering overspeed protection, and relates to a starting control method of an aviation power device. An overspeed protection strategy applied to the starting process of the tandem aviation hybrid power system is provided, the mechanical problem of overspeed risk of a power turbine in the starting process is solved by an electrical scheme, and a proper starting resistance value is determined in a test by taking the rated rotating speed of the power turbine as a guide. The starting control method of the tandem type aviation hybrid power system is divided into four steps of turboshaft engine starting, control rectification intervention, engine state improvement and electric propulsion system starting, the starting process is controlled through a time sequence, part coupling characteristics are decoupled to a certain degree, and for all index requirements of the starting process, the starting control method is suitable for starting of an electric propulsion system. And splitting to different steps to be realized respectively. The processing of the coupling characteristics of the parts is simplified, various index requirements of the system in a slow state can be quickly met, and the performance and development and design efficiency of the power system are improved.
