Study on Optimization Correction Method for Reverse Reservoir Inflow
This paper proposes an optimization correction method for reverse reservoir inflow based on the main rea-son that the monitored water level value cannot accurately reflect the actual water storage volume of the reservoir,in re-sponse to the unreasonable fluctuation problem of the inflow by water balance.The optimization correction model is es-tablished by setting the allowable water level correction amplitude and taking the minimum variation of inflow as the tar-get,and the model is solved by mixed integer programming.Taking the Three Gorges Reservoir outflow data as exam-ples,the inflow process by water balance is smoothed by the five-point three times smoothing method,the seven-point moving smoothing method and the optimization correction method,respectively.The advantages and disadvantages of the three methods are compared by the indicators of smoothing degree and water level deviation.Case studies show that the optimization correction method guarantees smoothness while the correction amplitude of the water level is smaller,which is more respectful of the water level monitoring facts and has good practical application value.
