摘　　要：本文结合实际工程中一次网的仪表安装情况,提出一种通过对矩阵进行分块处理,将供回水管道阻抗做合并处理,利用两种水力工况辨识管网阻抗的方法。并通过算例对提出的阻抗辨识方法进行应用效果验证,对不同的水力工况组合结果显示辨识得到的阻抗值的相对误差均在5%以内,满足应用要求。Combined with the instrument installation of a network in the actual project,this paper proposes a method to identify the impedance of the pipe network by blocking the matrix,combining the impedance of the water supply pipes and return pipes,and using two kinds of hydraulic conditions.And through the example to verify the proposed impedance proofing method,the results show that the relative error of the impedance value obtained by the identification is within 5%,which meets the application requirements.
