摘要
渠系中串联倒虹吸后引起水流的改变 ,影响了渠系的运行状态。利用圣维南方程组的特征线法、闸门同步操作技术和P +PR(比例 +比例复位 )算法 ,建立了串联倒虹吸渠系的控制模型 ,并编程对控制过程进行适时模拟。模拟结果表明 :该模型在较大的流量变化条件下 ,运行稳定、响应速度快、过渡时间短。
Series connection inverted siphons influence the flow conditions and operation of canal systems. By using characteristic method of Saint-Venant equations, P+PR algorithm and technique of synchronous operation for gates; a mathematical model of multireach canal systems with inverted siphons in series has been developed. And it was programmed to simulate the control process. The simulation results show that the model performs well in the condition of large variation of demanded discharge, and takes the advantages of stability, fast response speed, less overshoots and steady-state errors.
