摘要

配水网络(wdn)设计用于长时间运行,然而,预计其容量会随着时间的推移而减少。可用于提高其产能的大量选项,加上其液压复杂性,以及寻找最经济的解决方案,造成了一个难以解决的问题。因此,本文分析了三种修复策略的水力和经济效益:管道清洗、管道更换和泄漏修复。首先单独评估,然后通过使用粒子群算法最小化成本,将其合并为两个案例研究。首先,分析每个备选方案的投资与减少压力赤字之间的关系,以确定最佳策略,以及在哪个点上收益达到饱和。然后,考虑三种干预技术的组合进行优化,以验证是否存在任何技术的优先级,以及是否与个体性能相关。在经济和水力方面,管道更换是最好的干预措施,其次是管道清洗和泄漏修复。对于替代措施,很少有干预措施足以显著改善压力。此外,观察到在干预组合中,算法优先考虑联合解。

Hydraulic and economic analysis for rehabilitation of water distribution networks using pipes cleaning and replacement and leakage fixing
ABSTRACT Water distribution networks (WDNs) are designed to operate over a long period, however, it is expected that their capacity reduces over time. The large set of options that can be applied to improve their capacity, combined with their hydraulic complexity and the search for the most economical solution create a difficult problem to solve. Therefore, in this paper the hydraulic and economic benefits of three rehabilitation strategies: pipes cleaning, pipe replacement and leakage fixing. were evaluated individually first and then combined into two case studies, through a cost minimization using the PSO algorithm. Initially, the relation between the investment and the reduction in pressure deficit is analyzed for each alternative to identify the best strategy, and at which point the benefits are saturated. Then, an optimization considering the combination of the three intervention techniques is made to verify if there is a prioritization of any technique, and if it is related with the individual performance. in economic and hydraulic terms pipe replacement was the best intervention technique, followed by pipe cleaning and leak repair. For substitution, few interventions are sufficient to significantly improve the pressure. Moreover, it was observed that in the intervention - combined, the algorithm prioritizes joint solutions.
