用虚流量理论进行泵站位置与扬程优化计算

Optimal Calculation for the Positions and Boost Heads of Pump Stations with Virtual Flow Rate Theory

现行的输配水系统优化设计方法只能用于单泵站系统的优化计算，且泵站位置必须事先确定，本文从数学模型入手进行了改进，提出了将泵站设于管段上的方案，使得泵站位置与扬程可以同时被优化．文章通过解多泵站输配水系统优化设计数学模型，提出了改进后的虚流量理论，同时给出了实例．

The present methods of optimal design of water transportation and distribution systems are only used in calculation of single pump station, and the position of pump station has to be determined previously. This paper sets about to improve it from the mathematical model, proposes the conception of setting pump stations on the pipes, which makes the positions and boost heads of pump stations can be optimized at the same time. In this paper, an improved virtual flow rate theory is proposed through solving the mathematical model for the optimal design of water transportation and distribution systems with multiple pump stations. Furthermore, the practical example is supplied.
