WATER LEVEL ADJUSTING DEVICE AND WATER LEVEL ADJUSTING SYSTEM
PROBLEM TO BE SOLVED: To continue power generation by a generator and to suitably scour sand accumulated in a water tank while maintaining a permitted water-intake amount in a run-off-river hydroelectric power plant.SOLUTION: A water level adjusting device includes: a scouring gate opening measurement device 52 for measuring an opening D1 of a scouring gate 26; electric power measuring means for measuring a voltage V1 and an electric current I1 generated by a generator 22 with a voltage sensor PT82 and an electric current sensor CT80, and calculating electric power P1 by multiplying the voltage V1 by the electric current I1; and a control section 58c for generating an output target value of the generator so that a total water amount Q3 which is obtained by adding a first water amount Q1 passing through a pressure pipe 18 and a second water amount Q2 delivered from the scouring gate 26 is equal to or less than a permitted water-intake amount Q0 of a river based on the opening D1 of the scouring gate, a water level H1 of a water tank 14, and the electric power P1 generated by the generator 22, and controlling a water amount adjusting device 19.SELECTED DRAWING: Figure 2
【課題】流れ込み式の水力発電所において、発電機による発電を継続し、且つ許可取水量を維持しながら、水槽に堆積されている砂を適正に排砂する。【解決手段】排砂ゲート２６の開度Ｄ１を計測する排砂ゲート開度計測装置５２と、発電機２２が発電した電圧Ｖ１、及び電流Ｉ１を電圧センサＰＴ８２及び電流センサＣＴ８０により計測して電圧Ｖ１、及び電流Ｉ１を乗算することにより電力Ｐ１を算出する（電力計測手段）と、排砂ゲートの開度Ｄ１、水槽１４の水位Ｈ１、及び発電機２２が発電した電力Ｐ１に基づいて、圧力配管１８を通過する第１水量Ｑ１と排砂ゲート２６から排出される第２水量Ｑ２とを加算した合計水量Ｑ３が河川の許可取水量Ｑ０以下になるように前記発電機の出力目標値を生成して水量調節装置１９を制御する制御部５８ｃと、を備えることを特徴とする。【選択図】図２
