Abstract

PURPOSE: To make it possible to perform stable dam gate operation throughout normal time and transient phenomena by setting a calculation cycle adequately by providing a time setter.
CONSTITUTION: A calculation period set by time setter 10 is held by memory circuit 11. This calculation cycle is applied to water-level variation calculating circuit 4, which calculates a water-level difference in the calculation cycle. Flow-rate calculating circuit 5 calculates an inflow rate. The calculation cycle, on the other hand, is applied to smoothing circuit 2, which calculates a mean discharge rate. Gate opening calculating circuit 6 determines the mean discharge rate in the calculation cycle to calculate the extent of opening and gate driver 7 opens a gate. In the transient phenomenon of the inflow rate, setting the calculation cycle short obtains gate operation that conforms to variations of the inflow rate and at a normal time, setting the calculation cycle long makes it possible to prevent the transient operation of dam gate control.
