Application of computation-experimental methods to develop 70 MW steam turbine-electric generator prototype

摘要

The results of stability analysis of 70 Mw three bearing steam turbine-electric generator prototype and its vibration refining during the development are presented. Stability margins were risen sufficiently because of reconstruction of plain bearings and installing stabilizing units in diaphragm labyrinth seals. Positive results were confirmed by the presented experimental results obtained from the vibration monitoring system.
