Abstract

PURPOSE:To reduce a time variation of calculation inflow, by controlling a variation of the calculation inflow, which is caused by a variation of a water level of a reservoir, within a hydraulic allowable variation extent. CONSTITUTION:Gate discharge quantity Q0 is calculated from gate opening information (a) of a gate opening rate measuring instrument 2, and a reservoir water level information H of a reservoir water level measuring instrument 1, by a gate discharge quantity operator 3. Subsequently, inflow Q'i is calculated from the information H and the discharge quantity Q0 by a reservoir inflow operator 4, and is inputted to an inflow correcting part 5. Also, a correction value of an upper flow water level 6a is operated 6b by a correction reference value setting part 6, and hydraulic allowable variation quantity DELTAQmax is inputted to the reservoir inflow correcting part 5. In the correcting part 5, the hydraulic allowable variation quantity DELTAQmax is compared with variation quantity of the calculation inflow Q'i, and influence of a water level variation due to disturbance such as wind and waves, etc. is removed. Subsequently, its corrected inflow Q'i', is inputted to the circuit 4, is smoothed by arithmetic average, etc., and is outputted as the final reservoir inflow Qi.
