The invention provides a hybrid power system with double clutches arranged in a motor. The hybrid power system comprises an engine, a differential mechanism, a shock absorber, an engine power input shaft, the first clutch, the second clutch, the first motor EM1, a main deceleration driving gear, a power output intermediate shaft, a power output driving gear, a power output driven gear, a power output shaft, a second motor EM2, a low-gear driving gear, a low-gear driven gear and a synchronizer. By the adoption of the provided hybrid power system with the double clutches arranged in the motor, the double clutches are arranged in a rotor of one motor, so that the axial length of a transmission is effectively reduced. Through arrangement of the two clutches, a hybrid power structure is simplified, and a pure electric drive mode, a range extension type drive mode, an engine direct drive mode, a parallel connection drive mode, a series-parallel connection drive mode and the like are achieved; and the structure is simple, multiple functions can be achieved, one integrated double-clutch is used, only two pairs of normally-engaged gears are arranged in a coupling box, no gear shifting is needed in the operation process, and operation is stable.
