Abstract
PURPOSE: To secure stable steam condition in a steam turbine controller by detecting at the steam generating side even when operated at variable pressure and throttling a steam control valve in response to the decreased steam pressure by the steam pressure immediately before the malfunction as a standard to thereby stop lowering the main steam pressure.
CONSTITUTION: Steam from a steam generator 3 is supplied through a control valve 4 to a turbine 5 to thereby drive a generator 8. In this case, the control valve 4 is controlled by the output of a low value selector circuit 2 receiving the output of a governor 1 and the output of a main steam pressure regulator 7. At this time the regulator 7 comprises a first driven memory 79 for storing a signal immediately before change when a steam pressure signal from a steam pressure detector 6 exceeds predetermined variation rate, and a second driven memory 80 for storing the output of an adder 72 when the steam pressure drop is within the predetermined variation rate after the steam pressure signal is lowered over the predetermined variation rate due to malfunction or the like and the output of the adder 72 becomes lower than the output of the bias unit 73.
