摘要
通过研究给水管网系统特征,分析了给水管网水力平衡计算理论,建立了城市给水管网水力计算模型,利用牛顿迭代法求解模型的数值解,为得到最优结果,引入步长因子λ对系统初值进行修正,最终得到符合实际工况的管网运行数据。
According to research the characteristic of water supply network system, the author analyzes the calculation theory of water supply network hydraulic balance calculation, establishes city water supply network hydraulic calculation model, based on the model＇ s numerical solution solved by Newton iteration method, in order to get optimum result, introduces step factor A to modify system initial value, finally gets pipe network operation data which conforms to reality.
