State maintenance method, system and terminal for steam turbine generators

Abstract

Disclosed are a state maintenance method, system and terminal for steam turbine generators. The method comprises the following steps: based on characteristic models for the steam turbine generators trained by correlation information between historical data of each steam turbine generator, predicting input real-time data of one or more steam turbine generators to obtain prediction data of the steamturbine generators; and comparing prediction data of the steam turbine generators with real-time data of the steam turbine generators to obtain a state evaluation result corresponding to the steam turbine generator, and giving overhaul strategies for the steam turbine generators. Data-driven modeling method research is carried out on the basis of process real-time data streams, historical data and the like, potential process operation and equipment state information can be mined from the process real-time data streams, an equipment maintenance strategy is optimized according to an overall state evaluation result in combination with a state parameter evaluation system, and state maintenance of the steam turbine generators is realized. The invention has very important significance for improving operation capability of units and the equipment management level.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a method, system and terminal for condition maintenance of a steam turbine generator. Background technique [0002] In the power generation industry, the stable and safe operation of turbogenerators is of great significance. For a long time, the maintenance of turbogenerators has basically been temporary maintenance and regular maintenance (also known as planned maintenance). Practice shows that this maintenance method is blind and mandatory. It does not take into account the vast differences in the initial state of the equipment, nor does it consider the ever-changing operating status of the equipment under different environmental conditions, which often results in over-maintenance or under-repair of the equipment. , not only wasted a lot of manpower and material resources, but also affected the operation safety of the power plant. Therefore, how to implement condition-base...
