Disclosed is a single-mode combined power split-flow type hybrid power system. The single-mode combined power split-flow type hybrid power system comprises an engine, an input shaft, locking devices, a planetary gear train, first motors, second motors, an inverter, a power battery and output gears. The planetary gear train comprises a front-row sun gear, a planetary carrier, front-row gear rings, front-row planetary gears, rear-row gear rings and rear-row planetary gears, wherein each front-row planetary gear and the corresponding rear-row planetary gear are two gears which are manufactured on the same shaft. According to the invention, the deceleration from the second motors to output part gear rings is low, the requirement for the rotating speed of the second motors can be reduced, and miniaturization of the second motors is facilitated. When the single-mode combined power split-flow type hybrid power system is in a parking charging mode, the second motors can participate in power generation so that the higher charging current can be provided, and the power battery can be quickly charged. When the single-mode combined power split-flow type hybrid power system is in a purely electric driving mode, both the first motors and the second motors can participate in driving so that a vehicle can adapt to more working conditions in the purely electric driving mode.
