ABSTRACT:
The disclosed system overlaps the control operation for throttle and governor valves to shorten a steam chest warmup period by fully opening a pilot valve and closing down the governor valve to maintain rolling speed when the steam chest needs wraming and the throttle valve - governor valve transfer speed has not been reached. The system also sets a minimum rate of acceleration for vibration run through periods and allows speed changes at designated periodic speed change windows as long as stress is within an allowable range. The system further eliminates vibration transients during a speed change operation by providing a smoothed trend preventing speed holds from increasing unnecessarily.
