Optimal arrangement of impedance identification observation points in heating networks
摘要：
为了提高水力模型校核精度，寻找管网阻抗辨识和管网水力模型构建的最佳观测位置，根据供热管网设计参数计算管道节点压力和流量对阻抗的相对灵敏度，利用谱系聚类算法进行分析，确定一定监测条件下所需采集的数据。以1个供热管网为例，介绍了观测点优化布置策略的实现过程。结果表明，该策略结合已有的阻抗辨识方法可以得到满意的结果。
Abstract：
To determine the most appropriate observation points for impedance identification and hydraulic model calibration, introduces the relative sensitivity of observation points. Finds the most appropriate observed points to increase the accuracy of hydraulic model studies. Calculates the relative sensitivity matrix using the design parameter values of heating networks. Analyses the relative sensitivity matrix of nodes and pipes using a pedigree clustering algorithm. Determines the observed points selected in the process of impedance identification. Taking a heating network as an example, presents the processes of this method. The results are satisfactory from the method combining with existing impedance identification method.
