Abstract

PURPOSE: To obtain a good control performance of the control valve, by setting an objective value of a front pressure of the control valve with a function corresponding to a value of the load command for the gas turbine and controlling the control valve.
CONSTITUTION: A load controller 16 in the combined-cycle generating plant performs an operation such that a deviation of the sum of gas turbine (GT) load signals 20a, 20b and steam turbine (ST) load signal 21 from an objective load signal is obtained by a subtracter 23 to produce demand load signals for each GT through a regulator 24. Said load signal is compared with the load signal 20a by a subtracter 25 to output a GT fuel control signal. At this time, a control valve 12 that controls the pressure of a steam turbine 6 is controlled by a front pressure controller 17. The constitution of said controller 17 comprises a function generator 32, for producing a front pressure setting function on the basis of an output signal of the above described load regulator 24, time lag of first order function 33, for compensating a delay of the GT and ST load, a subtracter 29 and a regulator 30.
