Identification of Shaft Orbit and Application in Steam Turbine Vibration Monitoring Diagnosis System;

Research and Development of Steam Turbine Vibration Monitoring and Fault Diagnosis System;

In doing so,we take into account the change of the bearings′ viscosity and density with that of temperature and pressure and then obtain the transient response of the elliptical bearing of a steam turbine when the load suddenly changes.

Load rejection tests for 1 000 MW steam turbine units;

On energy conservation and loss reduction of large-scale steam turbine units;

Online Analysis about Thermal Economical Performance of Large Steam Turbine Unit on Full Work Conditions;

It causes the unit vibration because of imperfect procedure,careless work,and imperfect operation rules in the course of installing turbine units.

In order to solve the technological problem with bad economy for the large-size turbine unit in Shanxi power grid,develop and apply diagnostic technology in energy-conservation of the large-size turbine.

For disturbance of the thermal effects of turbine unit,doing analysis in light of the actual situation of different units under different disturbance,Giving three calculation methods(the method of thermal balance,the method of equivalent enthalpy drop,the method of matrix analysis).

Expert System of the Multi-Symptom Fuzzy Diagnosis of the Vibration Faults of a Steam Turbine Set and Its Applications;

The state monitoring and trouble shooting technique for the steam turbine set are the very important measures to guarantee the steam turbine to be well operated.

Since the numerical electro-hydraulic control system of Yangzi Petro-Chemical Cogeneration Power Plant s steam turbine set was put in operation, its fire resistant fluid system incurred quite a number of faults, which caused production cost to increase, handicapped steam delivery to the chemical installations and also effected steadiness of power supply.

The meaning of building remote monitoring and diagnosis analysis system of steam turbine sets are analysed.

The fault diagnosis of steam turbine sets was carried out by using the continuous wavelet transform scalogram and wavelet gray moment,the standard scalogram and the value range of wavelet gray moment corresponding to typical faults are determined too.
