The invention discloses a spare power automatic switching method, system and equipment suitable for a hydraulic power plant and a storage medium. The system comprises a spare power automatic switching device, all comprehensive protection measurement and control devices and a process layer switch. When a certain plant transformer of the hydraulic power plant breaks down, a standby plant transformer power supply with the maximum standby capacity of a bus adjacent to the fault plant transformer is selected as an optimal standby power supply, and a bus connected with the plant transformer serves as an optimal standby bus; if the standby capacity of the optimal standby power supply is greater than the load capacity carried by the fault factory transformer before the fault, the optimal standby power supply is preferentially put into use through a section switch; on the contrary, the spare power automatic switching device issues a load shedding instruction to the comprehensive protection measurement and control devi
