Analysis of Turbine Rotor Fault Diagnosis Method

The role of steam turbine in generating set is very important. During the operation, the rotor state is monitored by high-frequency vibration sensor. With the rapid development of computer, sensor and communication technology, modern machinery and equipment is developing towards the direction of electromechanical integration, as a result of the monitoring equipment group of large scale and the required point, single point more high sampling frequency and data collection time span is long, so the monitoring data of exponential growth, mechanical equipment health monitoring field enter the era of "big data". The traditional method of turbine rotor fault diagnosis has encountered some difficult technical problems and bottlenecks. This paper first introduces the fault mechanism of turbine rotor. Then, the fault diagnosis methods of turbine rotor proposed by many scholars this year are analyzed, the fault characteristics of turbine rotor are summarized and the challenges are discussed, and the direction of further research is prospected.
