Abstract :
Based on matrix equations of spatial heating networks hydraulic calculation method, impedance identification equation is proposed which can be transformed into optimization problem solved by hybrid genetic algorithm. Then, impedance identification results of different numbers of operational conditions are quantitative compared by evaluation function values, which can be used to obtain the optimal number of operational conditions when the number of pressure measurement nodes is fixed. For the actual pressure measurement data has error, they are replaced by hydraulic calculation numerical simulation results to obtain more accurate identification comparison results. The above optimal processes are verified in case study and can be applied to actual heating networks.
