谈阀门调节技术在管网系统优化调度中的应用

Discussion on the application of valve-adjusting technology in optimal pipeline system dispatching

结合已有的研究成果,利用K—ε方程建立了数学模型,分析讨论了阀门开启度的变化对水头损失变化的影响,并在对管网节点压力准确判定的基础上,利用阀门开启度对节点压力的灵敏度方程判定最佳调节阀门及其最佳开启度,以减少事故和漏损量的发生。

Combine the results of previous studies, establish mathematics model by using K-εequation, discuss the change of the head loss caused by the changes in the valve opening degree. Based on determining of the pressure pipe network node accurately, we will determine the best regulator valve and its best opening degree by valve opening degree of the node pressure sensitivity equation, in order to reduce the accidents and leakage safety.
