Abstract

The central heating system is an important infrastructure of city, because it has the advantages of energy saving, environmental protection and the quality of heat supply and so on, will be more widely used in the "energy-saving emission reduction" in the environment. Heat supply network is an important part of centralized heating system, with a large scale, complex structure, huge investment and social impact of major characteristics, so much concern. At present, more research, hydraulic calculation of heating network operation scheduling and reliability analysis in several aspects, and heating pipe network resistance characteristics identification research is less. If unable to accurately obtain the actual operation of heating pipe network resistance coefficient under the condition of hydraulic condition, heating pipe network calculation and operation scheduling are only stay in theoretical analysis and qualitative simulation. Calculation and analysis of the results are often inconsistent with the actual operation, thereby greatly reducing the research results and practical value. At present, for the study of the pipe friction parameters of the few, the research of heating network identification model is still relatively small, single and identification method, identification accuracy degree is not high, the identification of time-consuming calculation. Therefore, in-depth study of the heating pipe resistance coefficient identification problem has important theoretical significance and practical value.
