摘要
针对传统厂网河拓扑分析不全面、低效且缺乏有效运行指导的弊端,提出了一种面向厂网河系统的拓扑分析方法,实现流向逆坡、断接、混接等问题的自动定位、修正以及混接点治理优先性权重的计算,并以西南某地级城市的厂网河系统为应用案例,完成了自动化拓扑分析过程。案例结果表明,厂网河系统拓扑自动分析流程具有耗时短(4 min)、拓扑问题精准识别与修正的特点,同时给出混接点优先建设意见。拓扑问题修正后的连通区域比例从18.8%完善至全区域覆盖,本方法实现了厂网河的水动力路径的贯通,为厂网河一体化运行提供精确有效的数据保证。
The topology analysis of the Plant-Pipeline Network-River Integrated System(PPRIS)faces some inefficient problems such as the cumbersome steps and the nonsense operational guidance.In this study,an automatical analysis of topological relations method for PPRIS is established based on the related concepts of complex network,and algorithms such as flow direction determination,misconnection combing,disconnection identification,extension correction,discharge outlet traceability traversal and calculation of weighting factors for mixed pollution have been developed.Taking the PPR analysis of a city of southwest China as an application case,the automated analysis and problem correction of the topological structure have been realized.The case results show that this method has the characteristics of short time-consuming(4 min)and high accuracy(100%)in the process of combing the topological structure of the complex PRRIS,which also provides more reasonable opinions on the priority construction of the mixed nodes.The proportion of the connected area after the correct process has been improved from 18.8% to full area coverage,which realizes the connection of the hydrodynamic path of the PPRIS,and provides accurate and effective data guarantee for the management of the PPRIS.
