Hydraulic Characteristics Analysis of Long-Distance Water Resources Joint Dispatching Project Based on Hydrodynamic Model

从水力调度中的非恒定流现象入手,针对长距离水资源联合调度工程建立水动力模型。该模型可分为有压管线模型与明渠模型两部分,以连续方程与运动方程为主体构成,同时对模型性能进行验证,并进行模拟分析。结果显示,模拟结果与实测具有一致性,研究设计的模型均实现了收敛性良好的模拟运算,能够实现水力精准模拟。同时,能通过工况模拟实现对工程运输测试段1-4段的运输段水力状态的精准分析,为工程水力分析提供技术基础。

The research starts with the unsteady flow phenomenon in the hydraulic dispatching,and establishes a hydrodynamic model for the long-distance water resources joint dispatching project.The model can be divided into two parts:the pressure pipeline model and the open channel model,which are mainly composed of the continuous equation and the motion equation.And the research verifies the performance of the model and carries out simulation analysis.The research results show that the simulation results are consistent with the actual measurement,and the models designed in the research have achieved good convergence simulation,and can achieve accurate hydraulic simulation.At the same time,it can accurately analyze the hydraulic state of the transportation section of the engineering transportation test section 1-4 through the working condition simulation,which provides the basis for the engineering hydraulic analysis.
