CALCULATION DEVICE, CALCULATION METHOD AND CALCULATION PROGRAM OF OUTFLOW RATE
To provide a calculation device allowing missing of an outflow rate and an inflow rate needed for dam management to be prevented even when opening angle data of outflow rate facilities are missed.SOLUTION: A calculation device comprises: a reservoir level acquisition section 31 for acquiring a measured value of a reservoir level of a dam reservoir; an opening angle data acquisition section 32 for acquiring a measured value of an opening angle of a gate valve of outflow facilities 5 of the dam reservoir; an outflow rate calculation section 33 for calculating an outflow rate from the outflow facilities 5; and an opening angle storage section 282 for storing a latest measured value of the opening angle of the gate valve as a storage value of the opening angle, wherein the outflow rate calculation section 33 calculates an outflow rate using a measured value of the reservoir level supplied from the reservoir level acquisition section 31 and a measured value of an opening angle supplied from the opening angle data acquisition section 32 when the measured value of the opening angle is supplied from the opening angle acquisition section 32, and calculates an outflow rate using a measured value of a reservoir level supplied from the reservoir level acquisition section 31 and a stored value of the opening angle stored in the opening angle storage section 282 when no measured value of the opening angle is supplied from the opening angle acquisition section 32.SELECTED DRAWING: Figure 1
【課題】放流設備の開度データが欠測となってもダム管理に必要な放流量や流入量の欠測を防止する。【解決手段】ダム貯水池の貯水位の計測値を取得する貯水位取得部３１と、ダム貯水池の放流設備５のゲート・バルブの開度の計測値を取得する開度取得部３２と、放流設備５からの放流量を算出する放流量算出部３３と、ゲート・バルブの開度の最新の値を開度の保存値として記憶する開度記憶部２８２と、を有し、放流量算出部３３が、開度取得部３２から開度の計測値が供給されるときは、貯水位取得部３１から供給される貯水位の計測値と開度取得部３２から供給される開度の計測値とを用いて放流量を算出し、開度取得部３２から開度の計測値が供給されないときは、貯水位取得部３１から供給される貯水位の計測値と開度記憶部２８２に記憶されている開度の保存値とを用いて放流量を算出する。【選択図】図１
