The invention relates to an electric wheel mining dump truck, in particular to a power control system of a new energy electric wheel mining dump truck. The defects and problems existing in an electricwheel mining dump truck which adopts a diesel generator set to provide power are solved. The power control system of the new energy electric wheel mining dump truck comprises a lithium battery, a hydrogen fuel cell engine, a direct-current bus, a first DC/DC triple chopper, a second DC/DC triple chopper and a third DC/DC triple chopper, wherein the lithium battery and the hydrogen fuel cell engine are respectively connected in parallel with the direct-current bus; the first DC/DC triple chopper takes power from the direct-current bus and supplies power to an armature winding of the first DC motor; the second DC/DC triple chopper takes power from the direct-current bus and supplies power to the armature winding of the second DC motor, and the third DC/DC triple chopper takes power from thedirect-current bus and supplies power to the excitation windings of the first DC motor and the second DC motor. The power control system adopts a hydrogen fuel engine and lithium battery hybrid energy system to replace the diesel generator set to provide power.
