Paper Title:
Analysis on Torsional Vibration Characteristics of Steam Turbine Generator Shafts
  Abstract

This article introduced the four-terminal network method, Riccati transfer matrix method and finite element method respectively, and the applications of three methods in inherent characteristics analysis of turbine generator units’ torsional vibration. Considering an actual case of 600 MW units in one power, the natural frequencies and normal vibration mode of units’ torsional vibration were worked out through the three methods, and compared with the testing natural frequencies, the results showed that the calculation precisions of three methods are very high, and the three methods can be used to analyze actual units. Comparatively, the results obtained by four-terminal network method are closer to testing natural frequencies with a higher calculation precision.
