The invention relates to a tractor electric drive parallel hybrid power system and a control method thereof. The system comprises a hydraulic pump, a hydraulic pump driving motor, a battery managementsystem and a power storage battery which are connected in sequence, and an engine, a torsion damper, a one-way clutch and an electric drive parallel hybrid power gearbox which are connected in sequence. The electrically-driven parallel hybrid power gearbox comprises a box body, and a planet row, a power switching element, a driving motor and a gear device which are arranged in the box body, the power switching element comprises a planet row input end clutch and a planet row output end clutch and is used for achieving switching of the modes including pure electric mode, rotating speed couplingparallel connection mode and torque coupling parallel connection mode. Compared with the prior art, the system has multiple operation modes such as pure electric operation, rotating speed coupling parallel connection and torque coupling parallel connection, energy conservation and consumption reduction can be achieved in the modes of charging through an external power source, restraining load disturbance, stabilizing engine working points and the like, and the system has the advantages of being wide in rotating speed adjusting interval, compact in structure and high in applicability.
