Effective Method of determining the Water Discharge of a Pondage I considering Operating Constraint

수력기 운전제약을 고려한 저수지식댐의 효과적인 사용수량 결정에 관한 연구

In this Paper, the effective method of determining the water discharge of a pondage hydro-unit for hydro dispatch is proposed. The water discharge of a pondage hydro-unit can be determined subtracting the spillage discharge from summation of the inflow and the pondage according to variation of the water level of the reservoir. Proposed method calculates the inflow using the duration curve, the water level from initial level on January 1, and the spillage discharge from the water discharge.
