摘要： PURPOSE:To secure a desired turbine lifetime and shorten a start/stop time. CONSTITUTION:A lifetime consumption ratio curve representative of a relationship between a lifetime consumption ratio and a thermal stress in various temperatures is previously determined. Furthermore, a lifetime consumption ratio limit value per start/stop is determined in advance on the basis of a preset turbine lifetime and future start/stop times (step 2). In the case of execution of a desired start/stop pattern, a maximum thermal stress generated in a turbine rotor is determined (step 3). A lifetime consumption ratio only in the case of execution of the desired start/stop pattern is determined on the basis of the maximum thermal stress, an estimated temperature of the turbine rotor in the case of the execution of a start pattern and the lifetime consumption ratio (steps 4, 5). The obtained lifetime consumption ratio is compared with the lifetime consumption ratio limit value (step 6). On the comparison result, the start/ stop pattern is changed within a range not exceeding at least the lifetime consumption ratio limit value (step 8).

摘要： PROBLEM TO BE SOLVED: To suppress thermal stress in a second stage reheater main body, its thermal transmission pipe and a low pressure turbine at the time of service-in of the second stage reheater in a reheating steam turbine. SOLUTION: This device is provided with a heating steam pressure regulating valve 9, a reheater operation data receiving part 22 and a saturation pressure-temperature function curve 23. The heating steam pressure (flow rate) regulating valve 9 is arranged for adjusting extracted steam (main steam) of a high pressure turbine flowed into a second stage reheater 5. An outlet heated steam temperature 17 of a first stage reheater 4 is input to the reheater operation data receiving part 22. Saturation pressure of the heating steam temperature in the second stage reheater 5 is calculated based on the saturation pressure-temperature function curve 23. A second stage reheater heating steam pressure setting function generator 20 is arranged for setting a lower limit set pressure at the time of service-in of the second stage reheater 5 by adding required excessive pressure for heating to the calculated saturation pressure. A heating steam control means 10 is arranged for controlling the regulating valve 9. The heating steam set pressure of the second stage reheater 5 is set equally to the saturation pressure of the outlet heated steam temperature of the first stage reheater 4 based on the outlet heated steam temperature of the first stage reheater which is previously sensed at the time of service-in of the second stage reheater 5.
