The invention discloses an energy management method of a fuel cell hybrid power system for a locomotive. Power output of a fuel cell system is taken as a main body of a control method, an energy storage system is taken as a supplement of locomotive peak power and rapid loading and unloading working conditions, so that the power requirement of the hybrid power system on the energy storage system is lowered; the size and weight of the energy storage system can be reduced under the condition of the same locomotive power, so that the cost of the hybrid power system is reduced, and the application value of the hybrid power system is improved. The energy management of the fuel cell hybrid power system is carried out by comprehensively considering various factors such as a driver controller pole position, a locomotive operation working condition and an energy storage system state, so that the situations such as high power and long-time power requirements which suddenly occur in the locomotive application process can be better coped with; therefore, the method can meet the power requirements of various operation conditions in the locomotive operation process, and the working condition adaptability of the fuel cell hybrid power system is improved.
