Method and system for evaluating health status of major equipment

Abstract

The invention discloses a method and a system for evaluating the health status of major equipment. the evaluating method comprises the steps of S1, receiving major equipment selected by a user, and evoking a fault tree and an evaluation model both corresponding to the selected major equipment out of a database, wherein the fault tree is pre-established based on the corresponding equipment characteristics of the major equipment and the evaluation model is pre-established based on the corresponding operating parameters of the major equipment and the above fault tree; S2, acquiring the fault information of the major equipment and the information of the operating parameters of the major equipment; S3, according to the evoked fault tree and the evaluation model, conducting the calculation and analysis on the acquired fault information and the information of the operating parameters of the major equipment so as to acquire the information of a status assessment result. According to the technical scheme of the invention, the health status of the major equipment can be timely and correctly evaluated, so that a reasonable maintenance strategy can be conveniently formulated. Therefore, the reliability of the major equipment is improved, and the service life of the major equipment is prolonged.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a method and system for evaluating the health status of major equipment. Background technique [0002] In nuclear power plants, major equipment such as main pumps, generators and main transformers are crucial to the normal operation of nuclear power units. However, such equipment maintenance and replacement costs are very expensive. Therefore, how to correctly assess the health status of equipment, find problems in time and formulate reasonable maintenance strategies has become an important task in the daily operation of nuclear power plants. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and system for evaluating the health status of major equipment, which can correctly evaluate the health status of major equipment, in view of the above-mentioned defects in the prior art that cannot correctly evaluate the heal...
