摘要
进行环状给水管网优化的目的是求解管段的经济管径,要实现这一目的,分配管段的初始虚流量是前提。文章指出用最小平方和法来分配管段的初始虚流量,有时会出现某些管段虚流量与同一管段初始真实流量方向不一致的现象,提出了将节点累计法用于初分管段虚流量可以很好地解决这一问题。算例表明用这一方法是可靠和有效的。
In the optimization of the looped water supply pipe network,the purpose of which is to get economical diameter of pipe-segments, the initial imaginary flow of pipe-segments needs to be distributed properly. But the method of least square summation, which is commonly used to distribute the initial imaginary flow, can not offer satisfying results. On some occasions, the direction of the initial imaginary flow of some pipe-segments does not coincide with that of the initial real flow of the same pipe-segments. Study in this paper shows that using the method of node summation can solve the problem better. Calculation examples indicate that the presented method is reliable and effective.
