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.

The two calculation methods,such as simplified variable condition method and thermodynamics method,are introduced chiefly in the paper,and used to analyze energy-loss of main steam parameter for condensing steam turbine.

Aimed at the status of idling a lot of condensing units in northeast China, two 200 MW condensing units are transformed into heating units through slotting and extracting steam in Haerbin No.

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).
