The embodiment of the invention can improve the overhaul benefit of the equipment state and provides a new research idea for formulating the management strategy of the service life of the equipment. The patent does not consider that the data volume is larger and larger along with the increase of the power transmission and transformation equipment, the system operation efficiency is influenced, and the timeliness of information is difficult to guarantee.
CN201510611287.6 proposes a method for evaluating the state of power transmission and transformation equipment based on live detection. The method comprises the following steps: (1) acquiring state quantities of components in the power transmission and transformation equipment; (2) setting a deduction value: setting corresponding deduction values according to the grading standard by the state quantity; (3) calculating a state quantity score, a family defect score and a quality event score; (4) device status score ═ status component score × × ×; (5) if the equipment state score is 85-100 points, the equipment is in a normal state; if the equipment state score is 75-85 points, including 85 points, the equipment is in an attention state; if the device status score is 75 points or less, the device is in an abnormal state. According to the method, the equipment state score is calculated according to the equipment state quantity score, the family defect score and the quality event score, and then the state of the power transmission and transformation equipment is evaluated; the method has simple calculation and short period.
