Analysis of Conveyance Efficiency of the Yellow River to Qingdao Project Based on Mike11

为提高引黄济青工程的调度运行管理水平,基于Mike11构建引黄济青工程水动力模型确定了不同流量下输水效率,即选取8个水位模拟断面,选取2018年3月16日~6月13日的调度运行数据进行模型参数率定和验证,利用率定好的模型计算6种不同流量下的输水效率。结果表明,当引黄济青上节制闸的流量q≤25 m3/s时,工程输水效率为0.801 0;当25 m3/s40m3/s时,工程输水效率为0.879 4;同渠段随着流量的增大,输水效率越大,因此在实际调水过程中,大流量输水会提高调水效率,根据确定的不同流量下的输水效率,为引黄济青调水工程的精细化调度提供调水依据。

In order to improve the scheduling operation management level of the Yellow River to Qingdao Project,based on MIKE11,the hydrodynamic model of the Yellow River to Qingdao Project was constructed to determine the water conveyance efficiency under different flow conditions.Firstly,8 water level simulation sections were selected.Then dispatching operation data from March 16 to June 13,2018 were selected to calibrate and verify parameters of the model.The calibrated model was used to calculate the water conveyance efficiency under 6 different flow conditions.The results show that when the flow of upper control gate of the Yellow River to Qingdao Project q≤25 m3/s,the water conveyance efficiency is 0.801 0;when 25 m3/s40 m3/s,the water transfer efficiency of the project is 0.879 4.With the increase of flow in the channel section,water conveyance efficiency increases.Therefore,in the actual process of scheduling,large-flow scheduling will improve the water schedule efficiency.According to the determined water conveyance efficiency under different flow conditions,the water transfer basis was provided for the fine scheduling of the Yellow River to Qingdao Project.
