Zusammenfassung:The invention discloses a substation equipment maintenance method based on task reliability analysis, and the method comprises the steps of building a fault tree for possible fault points of a substation system; respectively determining minimum cut sets of possible fault points by adopting a fault tree analysis method; establishing a reliability incidence matrix of the possible fault points; calculating the task reliability of the possible fault points; determining a reasonable fluctuation range of the task reliability of the possible fault points; performing sensitivity analysis, and determining the fluctuation interval of the availability rate of the information equipment and the fluctuation interval of the availability rate of the physical equipment allowed by the transformer substation; and calculating the maintenance period of the equipment according to the determined fluctuation interval of the availability rate of the equipment. According to the reliability requirement of the fault point, sensitivity a
