Description

technical field [0001] The invention belongs to the technical field of steam turbine vibration fault diagnosis, and relates to a steam turbine vibration fault diagnosis using deep learning, that is, a steam turbine vibration fault diagnosis method based on a deep learning artificial neural network. Background technique [0002] At the moment when high-tech is advancing by leaps and bounds, the data of steam turbine vibration fault detection has entered the era of big data. Massive data not only provides sufficient analysis sources for the steam turbine vibration fault diagnosis system, but also brings interference to the system from redundant data. The vibration fault of the steam turbine has the characteristics of many types of detection data, a large amount of data, and high collection density. If traditional diagnosis methods are used, it will lead to adverse consequences such as huge workload and long working hours. How to efficiently carry out steam turbine fault diagn...
