Abstract

The invention discloses a power plant operation fault diagnosis system comprising a data acquisition module used for acquiring process parameters of power plant operation; the data preprocessing module is used for preprocessing the same kind of data at different moments and improving the relevance of different kinds of data at the same moment; the data association module is used for establishing an association matrix of data; and the neural network diagnosis module obtains a fault diagnosis result through the incidence matrix of the input data. The defects in the prior art can be overcome, and the accuracy of power plant operation fault diagnosis is improved.

Description

technical field [0001] The invention relates to the technical field of power plant operation monitoring, in particular to a power plant operation fault diagnosis system and a diagnosis method thereof. Background technique [0002] The power plant operation fault diagnosis system is an important guarantee for the safe operation of the power plant. The diagnostic logic of the existing power plant operation fault diagnosis system is based on historical experience data, and directly collects fault signals in operating parameters. Although this method can diagnose typical fault types that have occurred in the past, it cannot effectively diagnose atypical faults. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a power plant operation fault diagnosis system and its diagnosis method, which can solve the deficiencies of the prior art and improve the accuracy of power plant operation fault diagnosis. [0004] In order to...
