Abstract

The present invention provides a steam turbine remote intelligent operation and maintenance service system, and belongs to the technical field of steam turbine operation and maintenance. The inventionaims to solve the problems that an existing steam turbine operation and maintenance method cannot timely and comprehensively achieve operation and maintenance of a steam turbine and is low in efficiency. The system comprises: a telemetry database used for obtaining, storing and storing telemetry data; a comprehensive database which reflects a set of current diagnosis reasoning states and is usedfor storing various fault symptom facts required by diagnosis reasoning and middle results and fault reasons generated in the reasoning process; a diagnosis knowledge base used for storing steam turbine fault diagnosis knowledge; a characteristic parameter extraction module which is responsible for analyzing the telemetry data and extracting characteristic parameters as fault symptom facts; and afault reasoning machine which is used for reasoning according to a comparison result of the characteristic parameters and the threshold value, and is responsible for explaining a diagnosis reasoning basis to a user and giving a corresponding fault processing plan. The steam turbine remote intelligent operation and maintenance service system is mainly used for steam turbine operation maintenance.
