ABSTRACT:
The present invention relates to a method of controlling the operation of large rotary machines such as steam turbines and generators in a thermal power plant or nuclear power plant. More specifically, the invention relates to a method of controlling such operation as increasing or decreasing the speed of the rotary machines or stopping the operation of the rotary machines, by detecting vibration at the time of starting the operation or during the steady-speed operation, by analyzing the detected vibration signals to determine whether the operation is in normal condition or abnormal condition, and by detecting or forecasting the cause in case the operation is in abnormal condition.
