Transformer substation primary and secondary equipment state monitoring method and system based on equipment state calculation

The invention discloses a transformer substation primary and secondary equipment state monitoring method and system based on equipment state calculation, and the method comprises the steps: defining the equipment state of primary equipment for an object according to an interval, and enabling the equipment state of the primary equipment to be the logic operation of the opening and closing positionsof the primary equipment contained in the interval; defining an equipment state of the secondary equipment by taking the secondary equipment as an object, wherein the equipment state of the secondaryequipment is a logical operation for a pressing plate input/output state contained in the secondary equipment; with the primary equipment state as a reference, enabling the equipment state of the secondary equipment and the primary equipment state to have a fixed corresponding relationship, and defining an association relationship between the primary equipment state and the secondary equipment state; calculating the equip
