Abstract:
The
torsional vibration of the large scale turbo-generator shaft system is
the responsive result of the mechanical-electrical coupling. Because the
transformation of electric net load is very complex, the impulse
response on the generator shaft system is stochastic, paroxysmal and
multiformed. Based on several typical outer powers actions, the response
characteristic of torsional vibration of a 300 MW turbo-generator is
simulated by solving the vibration wave equation of the continuous mass
system. The forced torsional vibration of the turbo-generator shaft
system is examined under the different operational condition of the
system.
