结合模糊聚类分析理论,提出一种基于反映管网阻力特性系数变化的热网流量监测点优化布置方法.该方法能反映管段阻力特性系数变化对管网运行参数的影响,为实现热网阻力特性辨识提供了必要条件.通过采用直接求解析解的方法取代管网微观分析方法,来计算阻力特性系数影响矩阵,确保了阻力特性系数影响矩阵的准确性,提高了测点优化计算的精度.
An optimal arrangement method of flow monitoring points in heat-supply network based on fuzzy clustering theory is presented in this paper.The effect of the change of resistance coefficients on the operating parameters in heat-supply network is discussed in detail.the identification method of these resistance coefficients is introduced.In the computation of the influence matrix of resistance coefficients,the microcosmic analysis is replaced with the analytic solution,which ensures the accuracy of the influe...
