Zusammenfassung:PROBLEM TO BE SOLVED: To control the opening of a dam gate to an appropriate value while suppressing control delay.SOLUTION: A gate control device 10 for controlling a dam gate 3 includes: a water level measuring unit 11 measuring a dame water level H; a target opening setting unit 12 setting a target opening DT of the dam gate 3 on the basis of a clearance G between the dam water level H measured by the water level measuring unit 11 and the dam gate 3; a driving control unit 13 driving the dam gate 3 on the basis of the target opening DT set by the target opening setting unit 12; and a predicted water level calculation unit 14 predicting a dam water level at planned time at which a dam gate opening reaches the target opening DT. The target opening setting unit 12 corrects the target opening DT of the dam gate 3 on the basis of a clearance between the predicted dam water level calculated by the predicted water level calculation unit 14 and the dam gate 3. 【課題】制御の遅れを抑制しつつダムゲートの開度を適切な値に制御すること。【解決手段】ダムゲート3を制御するゲート制御装置10は、ダム水位を測定する水位測定部11と、水位測定部が測定したダム水位Hとダムゲートとの離間距離Gに基づいて、ダムゲートの目標開度DTを設定する目標開度設定部12と、目標開度設定部により設定される目標開度に基づいてダムゲートを駆動する駆動制御部13と、ダムゲートが目標開度に到達する予定時刻におけるダム水位を予想する予想水位算出部14とを備える。目標開度設定部は、予想水位算出部で算出した予想ダム水位とダムゲートとの離間距離に基づいてダムゲートの目標開度を補正する。【選択図】図1
