Abstract
PURPOSE:To control abnormal rise of pressure in the high pressure steam reservoir and prevent actuation of the safety valve, and avoid the total plant shut down, by controlling the pressure control valve and the cooling water control valve by the signal corresponding to the steam flow at the time of an emergency shut down of the steam turbine. CONSTITUTION:In a system composed of an unit 34 provided with a gas turbine 2, air compressor 3 and electric generator 4 so as to allow the boiler 7 to generate steam by exhaust gas of the turbine 2 and the steam turbine 12 which is combined to the unit 34 via the high and low pressure steam reservoirs 9 and 19, the regulating valve 11 is closed when the steam turbine 12 is shut down for emergency. Thereby the pressure in the steam reservoir 9 is increased so that the output of the pressure control gauge 28 is added to the connecting valve 18 via the high-value preference device 32 to increase the degree of valve opening. Simultaneously, the pressure control valve 20 and the cooling water control valve 22 are controlled by the calculator 27 to increase their opening degrees and the pressure rise of the high pressure steam reservoir is controlled.
