The invention relates to a planetary row hybrid power system and a vehicle. The power system includes an engine, first motors, a front planetary row, first lock-up clutches and second lock-up clutches; the engine is connected to the front second end of the front planetary row; the first motors are connected to the front first end of the front planetary row; the front first end is connected to a shell through the first lock-up clutches; and the second lock-up clutches have three different arrangement modes, and arrangement can be performed according to actual needs. The system has two engine direct drive modes, and can perform power switching according to actual needs and optimize the working points of the engine, so that economy can be enhanced; through the utilization of the two lock-up clutches, the problems, that the long-time direct driving of the engine cannot realized caused by the stalling of the first motors when existing power systems are in the engine direct drive modes, canbe solved; and the engine can directly drive the whole vehicle at a high speed when the vehicle drives in the high speed and the driving force demand of the whole vehicle is located at the efficient area of the engine, so that the efficiency of the power system can be enhanced.
