Fault Diagnosis Based on Condition Monitoring for Hydropower Unit in Operation

摘要

Based on condition monitoring and signal processing for hydropower units, many import methods of condition monitoring and signal analysis should be applied to units, which is a very important procedure to implement condition monitoring and fault diagnosis for hydropower units, equipment. The major operating modes of hydropower units and the corresponding analysis methods are described in this paper while implementing techniques on condition monitoring and fault diagnosis for units. And then based on field-testing experience, fault types for units'condition monitoring, signal analysis and diagnosis in different operating mode are given in detail.
