The invention relates to the technical field of energy storage hydropower station pipeline construction, in particular to an energy storage power station tunnel magnetic positioning system and method.The system comprises a processor, a solenoid line and a probe device, the probe device is installed at the rear end of a drill bit, and the solenoid line is located on the surface of a mountain where a preset tunnel track of an energy storage power station is located; the probe tube device is used for detecting a magnetic field generated by the solenoid wire and sending the magnetic field to the processor; the processor is used for determining the vertical distance between the drill bit and the surface of the mountain according to the magnetic field generated by the solenoid line and judging whether the drilling track of the drill bit is adjusted or not according to the vertical distance. Solenoid lines are arranged on the surface of a mountain, the problem that the distance measuring range of drilling and punchi
