摘要
结合管网的节点流量连续性方程组和管网的基本特性,改进了基本计算方程组,并给出牛顿迭代时更加有效的初值选择方法。采用该方法,对给水管网平差方法进行了改进,收敛性能有所提高。
Recommend an improvement of node-formula to analyze the water distribution network. According to the continuous equations of node-formula and basic characteristic of the network, the authors improve the equations for calculation and make an efficient method to choose initial value for Newton iteration. The method improved is easy to calculate and it＇s astringency is improved to some extent.
