The invention discloses an aeroengine generating system. An aeroengine generating set comprises an electric motor/exciter which is coaxially connected with a generator and an aircraft in the aeroengine power generating set; an aeroengine generating control system comprises a main controller, a starting excitation controller and a fuel adjusting controller which form a distributed bus control network in a mode of a bus; each controller is an independent node on the bus; and the main controller is a main node, and the fuel adjusting controller and the starting excitation controller are slave nodes. Each control part is designed in a modularizing mode and controlled in a distributed mode, so that the individual and general safe, economic, stable and reliable operation is realized in the aeroengine generating system, and the aeroengine generating set has the advantages of fast starting, smooth transition, high control precision, simple operation, strong adaptability and high reliability. Compared with a centralized control system in the prior art, each controller has the control function, and a universal standard device can be adopted, so that the aeroengine generating system is easy to expand and the maintenance cost is greatly reduced.
