N2 - Based on matrix equation of spatial heat-supply network hydraulic calculation method, impedance identification equation is proposed which can be transformed into optimization function of observation and numerical values. Optimal arrangements of pressure measurement nodes based on sensitivity analysis are presented. Then, existence of impedance identification equation solutions are studied when different sensitive nodes are selected. When the number of pressure measurement nodes is determined in the condition of the impedance identification equation has unique solution, we choose the most sensitive nodes, randomly selected nodes, and the most insensitive nodes to identify impedance respectively. Moreover, the optimal results of different sensitive nodes are quantitative compared by evaluation function values. The above optimal processes are verified in case study and can be applied to actual heat-supply network.
