Abstract

The invention discloses a power plant heating surface failure analysis method, device and equipment and a storage medium, and the method comprises the steps: extracting the attribute information of apower plant heating surface from a power plant heating surface inspection report, and carrying out the discretization processing; according to an FP-Growth algorithm, calculating a strong associationrelation between each attribute in the attribute information of the heating surface of the power plant and the metal failure form, and establishing an association rule; sorting the association rules in a descending order according to the confidence coefficient, and dividing a plurality of previous association rules into an early warning set; matching the to-be-detected power plant heating surfacedata with the association rule, and if the matched association rule is in the early warning set, sending an early warning signal. According to the invention, the strong association relation between the attribute information of the heating surface of the power plant and the metal failure form is established based on the FP-Growth algorithm; reliable association rules are extracted, a failure warning effect is provided for metal equipment with similar characteristics in an in-service unit, the purpose of predicting equipment failures is achieved, and metal equipment failures are prevented.

Description

technical field [0001] The invention relates to the technical field of metal monitoring in power plants, in particular to a failure analysis method, device, equipment and storage medium for a heating surface of a power plant. Background technique [0002] Metal technical supervision is to implement technical supervision and management of the whole process of metal equipment selection, design, manufacture, installation, commissioning, trial production, operation, decommissioning, maintenance and technical transformation, to find problems in time and take effective technical supervision measures to reduce To cut off the period failure and damage of metal equipment in the above-mentioned processes, in order to reduce metal failure, predict failure and make early maintenance and replacement, a complete legal system has been established to supervise and inspect the metal of power plants and carry out standardized management. Metal supervision can play a certain role in guaranteei...
