Abstract
PURPOSE: To prevent the generation of excessive stress and enable quick starting, by presuming the stress of a turbine and applying an instruction to a boiler control system depending on the excess of the presumed value over a limit value to correct a command for temperature, pressure or the like.
CONSTITUTION: The basic function of a control system 100 is to apply an optimal rate 4 of speed increase as a set point to a governor 10 or apply an optimal rate 6 of load change as a set point to an automatic load regulator 7 when thermal stress in starting or in load change falls below a limit value. A pressure signal PH1after the first stage is feedbacked to the automatic load regulator 7. An instantaneous load command 9 is applied to the governor 10. The control system 100 detects the possibility of combined load application in relation to the thermal stress, applies a combined application instruction 15 to a synchronous combined application function 14 and supplies a boiler control system 6 with command for correcting the temperature of the reheated steam 114 and a main steam temperature correction application 113 corresponding to the excess of the stress over the limit value.
