The invention discloses a parameter configuration optimization method for a hydrogen fuel cell hybrid power system for a tramcar. The parameter configuration optimization method comprises the steps that the maximum traction power and traction energy consumption of the tramcar in various driving states are calculated; based on the topological structure of the hydrogen fuel cell hybrid power system, initial parameter configuration of the fuel cell hybrid power system is completed; with comprehensive performance of the tramcar as a target, optimizing parameter configuration of the hydrogen fuel cell hybrid power system according to the obtained maximum traction power and traction energy consumption; and judging whether the output power and energy of the system meet the dynamic performance design requirements of the tramcar or not, and adjusting the mass weight coefficient and the volume weight coefficient. Normal operation and optimal configuration of the fuel cell hybrid power system for the tramcar are guaranteed, and the influence caused by too high system redundancy is reduced; the axle weight and size of the tramcar are limited, the earlier-stage purchase cost and the later-stage maintenance cost are reduced, the total size and the total mass are reduced, and the running economical efficiency of a hybrid power system is improved.
