The invention provides a running hybrid power system of a plug-in cotton picker. The running hybrid power system comprises an engine, a transfer case, a generator, a motor, a planetary gear train, a differential mechanism, an inverter and a power battery. By controlling the engine, a clutch, a motor and the generator, functions of pure motor driving and stepless speed regulation can be achieved in the operation process of the cotton picker. Through a planetary gear train, dual-motor power coupling is achieved, and the speed and working efficiency of the cotton picker are improved. By controlling the engine and the generator to work, energy conversion of the cotton picker in normal operation is achieved, chemical energy is converted into mechanical energy through the engine, mechanical energy is converted into electric energy through the generator, the electric energy is stored in the power battery, and finally the electric energy is converted into mechanical energy through the motor.
