针对供水管网的漏损探测与定位问题,采用虚拟变形法对管网各参数进行计算,通过漏损影响矩阵和流量影响矩阵来表征管网的状态,并提出了漏损探测定位的优化计算模型.由于管网漏损点数量事先难以预先获取,提出了基于贝叶斯理论的管网漏损探测、定位模型,并结合Matlab和Epanet编制了相应的优化计算程序,数值仿真结果验证了方法的有效性和可行性.
In order to solve the problem of leakage detection and location in water supply network, virtual deformation method is used to calculate the parameters of the pipeline network. The leakage matrix and flow influence matrix are used to characterize the status of the pipeline network. Model.Because the number of pipeline leakage points is difficult to obtain in advance, a Bayesian network-based pipeline leakage detection and localization model is proposed, and the corresponding optimization calculation program is compiled with Matlab and Epanet. The numerical simulation results validate the method Effectiveness and feasibility
