Abstract: Aiming at the shortcoming of speed low-pass filter on low
frequency performance, the concept of minimizing of torsionals is
presented. It reduces torsionals in feedback speed and has no influence
on low-frequency performance. Using speed after minimizing of torsionals
as feedback, the restraint is reduced considering torsionals stability.
The governor can have high response speed and has few effects on
torsionals stability. One method of minimizing of torsionals is
presented, who is assemble mode. Robustness is analyzed of the method.
It is verified using test data from industry site.
Key words: Steam turbine generator Torsional oscillation Minimizing of
