摘要

配水网络的关键特征是提供足够的供水,以满足所需的需求和令人满意的性能。本研究的目的是评价亚的斯亚贝巴Yeka Abado供应区的水力性能,并对评价中发现的问题提出纠正措施。在waterergems中建立了计算机模型,模拟了配水网络。基于客户电表数据创建了一个间歇场景,以检查系统满足研究区域当前需求的能力。开发了两种方案来评估系统在持续供应中满足当前和未来需求的能力。模型分析结果表明,在间歇运行期间,在供电后不久的高峰时段,一些路口的压力低于可接受标准。在其他时间步骤上,性能仍然令人满意。此外,对2044年预测未来流量的持续供应情景的分析表明,该系统无法满足研究区域不断增长的需求,需要在某个时候进行系统扩展工作。对于2021年的连续供应模型,结果表明性能优异,几乎满足所有验收标准。

Hydraulic performance evaluation of Yeka Abado supply zone of Addis Ababa's water distribution network
A water distribution network's crucial feature is providing adequate water supply to meet the required demand with satisfactory performance. The objective of this study was to evaluate the hydraulic performance of the Yeka Abado supply zone in Addis Ababa and suggest corrective measures to the problems obtained through the evaluation. A computer model was created in WaterGEMS to simulate the water distribution network. An intermittent scenario was created based on customer meter data to check the ability of the system to meet the current demand in the study area. Two scenarios were developed to evaluate the system's ability to satisfy the current and future demands in a continuous supply. The model analysis result indicated that pressure below the acceptance criteria at some junctions during peak hours, shortly after the supply, had resumed during intermittent operations. The performance remained satisfactory at other time steps. Furthermore, analysis in a continuous supply scenario for predicted future flows in 2044 indicated that the system is unable to meet the increasing demands in the study area, requiring system expansion works at some point. The results for a continuous supply model for 2021 indicated an excellent performance, with almost all the acceptance criteria being met.
