Abstract

PURPOSE: To improve the working ratio of a plant, by minimizing the variation of output by keeping a water-level of a drum constant by changing the set points of a feed-water controller and a pressure controller when changing over the speed of a recirculation pump.
CONSTITUTION: Bias 33, 34 and the signals of relay contacts C1, D1 are added to an adder 35 of a feed-water controller 17, and bias 37, an integrator 38 and the signals of relay contacts are added to an adder 39 of a pressure controller 20. The speed of a recirculation pump is changed over by make-and-break controlling relay contacts A1, A2, B1, B2, pressure set value and water-level set value are changed by decreasing or increasing water-level set signals and by diminishing or augmenting pressure set signals in response to the integral speed of the integrator 39 and the pressure set value is restored by altering the output of the integrator 39 after transient change settles down. Thus, the variation of the output of a turbine being accompanied by the change-over of the pump can be prevented, and the working ratio of a plant can be improved.
