城市煤气输配系统调压站的优化设计

Optimum Design of the Layout of the PRS for the Urban Gas Distribution System

城市煤气输配系统调压站的布局目前还没有有效的优化算法来求解。本文利用煤气系统的特点,在一些合理假设的基础上把低压管网分割成以各调压站为中心的若干流域,并引入调压站作用半径的概念,提出了一种根据调压站平均作用半径计算调压站布局的方法。实际应用表明,该算法是有效的.

It is a difficult which to obtain the optimal layout of the PRS (pressure regulator station) for the urban gas distribution system. To solve this problem, no efficient algorithm has been developed. In this paper, some hypotheses are put forward on the basis of the characteristic of the gas system, the lower pressure pipe system is divided into many regions which have the PRS as its centers, and the definition of efficient radius for the PRS is introduced. Based on the above work, an algorithm to obtain the optimal layout of the PRS is developed according to the given average efficient radius. Practical applications show that the method proposed is efficient.
