Abstract

PURPOSE: To stabilize the control of a low r.p.m. range thereby to make it possible to effect the control of accurate water supply by providing a non-linear circuit, which imparts the linear characteristics to the differential signals between the actual flow rate and the water supply demand, so that the differential signals may become coincident with the actual turbine r.p.m. signals.
CONSTITUTION: A non-liner circuit 19 is connected between a proportional integration operator 5 and a differential operator 6. The difference between the actual flow rate signals of a water supply flow meter 3 and a water supply demand is subjected to operation by an operator 4 so that the r.p.m. setting signals A, which are generated through the operator 5 and which have no-linear characteristics, are corrected to linear characteristics by the circuit 19. As a reslt, the signals A are converted into signals C1 so that they become coincident with the converted signals C0 of the actual r.p.m. Thus, the difference in contrability due to the r.p.m. detector of the high and low r.p.m. ranges is eliminated so that the hunting phenomena are prevented at the low r.p.m. range
