Abstract

PURPOSE: To continue stable feed-water operation, by precedently adding a stabilized compensation signal in response to the change of a system head.
CONSTITUTION: A system head is detected by means of a detector 6, the detected output is given to a primary delay element 8 of a compensation circuit 7, deviation between the delay output and the detected output of the system head detector 6 is computed by means of an adder 9 and the computed results are input to said adder 1 as a leading compensation control signal COM. Consequently, the compensation control signal COM functions as incomplete differentiation, and becomes large in response to the sudden change of the system head even if there happens the sudden change, thus precedently working the signal to a feed-water controller 2, then beforehand avoiding the effects of the disturbance that must be formed to the response of flow rate discharged. As a result, stable feed-water operation can be continued.
