Abstract

PURPOSE: To stabilize a load by a method wherein an output signal of a pressure- lift transducer is added to an output signal of a primary speed relay to output it into a secondary speed relay in a control system for a steam turbine operated under a pressure changing operation.
CONSTITUTION: A set value of a load and number of revolutions setting device 1 sets an opening of a steam regulating valve 5 through a primary speed relay 3 and a secondary speed relay 4. Steam from the steam regulating valve 5 and a load 7 are added in an adder 6 while an inertia 8 of a turbogenerator is detected in a regulator 9 as the load and the number of revolution and is fed back to a comparator 2. A deviation of pressures between a main steam pressure setting device 10 and a main steam pressure 11 is transduced into a lift in a pressure-lift transducer 13 and the opening of the steam regulating valve 5 is regulated by the lift. Thus, an insufficient following property of a pressure against a load requesting value is corrected and the load is stabilized at the desired value.
