Abstract
PURPOSE: To reduce the load on a computer and enable the quick starting of a turbine rotor, by predicting the time until the reaching of thermal stress at its maximum value after the application of a load to the rotor on the basis of the present temperatures of main steam and reheated steam and by permitting the aplication of the load to the rotor when the predicted stress is below a limit value.
CONSTITUTION: The digital computer is provided in a thermal stress prediction turbine control system 100. The time until the reaching of the thermal stress at its maximum value after the application of the load is predicted on the basis of the present temperatures of main steam and reheated steam by the control system 100 to predict the thermal stress corresponding to the time when the speed N of a turbine reaches a rated level. When the predicted stress is lower than the limit value, a load application permission 15 is given to a synchronous application means 14 and an optimal speed-up rate 4 is applied as a setpoint to a governor 10 and an optimal load variation rate 6 is applied as a setpoint to an ALR 7. Finally, the governor 10 applies a valve position instruction 13 to an actuator 12 to control the position of a regulating valve 11. Since the maximum value of the stress is predicted before the application of the load to the turbine rotor, predictions and calculations after that are dispensed with and the rotor can be quickly started.
