The invention discloses a partial discharge positioning method, device and equipment for power station cables and a storage medium, and relates to the technical field of electric digital data processing, and the method comprises the steps: taking all cables of a power station as a contrast reference, and deleting the same signal features (such as normal current signals; the current signal acquisition and positioning method has the advantages that the current signal acquired and positioned by the current signal acquisition and positioning method has no signals of the same type and is identified as abnormal characteristics (such as bubbles in a liquid medium, solid pores, seriously distorted space electric fields and other defects), and the current signal acquisition and positioning method is more accurate than the current signal acquisition and positioning method of a single cable. Other cables of the same power station serve as a control group, the probability of fault misjudgment is reduced, meanwhile, signa
