Research on Dynamic Control Scheme of Operating Water Level in Longyangxia Reservoir during Flood Season
Longyangxia Reservoir already has the engineering safety conditions and flood forecasting conditions for dynamic control of operating water level during the flood season,and the Longyangxia Reservoir can use the reservoir capacity compensation relationship with the upstream Maerdang Hydropower Station to carry out dynamic control of the operating water level during the flood season.The pre-discharge mode of Longyangxia Reservoir should adopt a multi-stage fixed pre-discharge mode.The effective prediction period of the flood forecast of Longyangxia Reservoir is 7days,the pre-discharge flow is 1000m3/s,1200m3/s,1500m3/s,the pre-discharge flow is 1000m3/s,1500m3/s,2000m3/s,2500m3/s,and the corresponding dynamic control range of the operating water level in Longyangxia Reservoir during the flood season is between 2594m to 2594.6m,and gradually decreases with the increase of the water level of the Mardang Reservoir.When the water level of Longyangxia Reservoir is lower than the flood limit water level,the discharge flow is mainly based on the power generation requirements,when the water level of the reservoir reaches or exceeds 2594m,the reservoir transferred to the operation water level dynamic operation or transferred to the flood control application according to the upstream water forecast and the reservoir water storage situation,and when the upstream water exceeds 2500m3/s,the reservoir is used according to the designed flood control application.
