Fault prediction processing method and device and medium

The invention provides a fault prediction processing method and device and a medium. The method comprises the steps of generating daily report data of a power station by obtaining operation parameters of each power generation device in the power station, and determining the daily average generating capacity (10% comparison of a single power generation device) of the power station according to the daily report data; for the identifier of each power generation device, if the daily power generation amount corresponding to the identifier of the power generation device is smaller than the daily average power generation amount of the power station (10% comparison of a single power generation device), the power generation device is identified as an abnormal power generation device; and acquiring an electric quantity difference value between the daily generating capacity of the abnormal fault power generation equipment and the power limiting value of the power station, comparing the electric quantity difference value
