APPARATUS FOR CONTROLLING TURBINE TURBINE AND METHOD OF REDUCING VIBRATION VALVE OF TURBINE SHAFT

摘要

[PROBLEMS] To prevent the turbine from being accelerated without the warp of the turbine shaft being removed. The turbine remote controller is configured to determine whether the turbine vibration value exceeds a starting operation alarm value smaller than the normal operation alarm value set in the case where the steam turbine is operated normally before the normal operation is performed after the start of the steam turbine And when it is determined that the turbine vibration value exceeds the starting operation alarm value, the occurrence of the abnormality is notified. When the turbine vibration value exceeds the starting operation alarm value, the turbine remote controller executes a vibration value reducing operation for operating the steam turbine at a rotation speed capable of removing deformation of the turbine shaft without causing hull movement .
