Abstract: In order to realize the behaviour and structure analysis of enterprise energy consumption process，according to the semantics of enterprise energy consumption process model，the dynamic and structure properties of the model are researched，and the energy conservation of enterprise energy consumption process model is analyzed.Firstly，to describe the dynamic logical relation of material flows and the static topology structure of production process，the concepts and definitions of static and dynamic incidence matrix are proposed，and then the dynamic balance quantity and steady running range associated with the model relevant behaviour are researched respectively.Moreover，based on the research about model weighted conversation，the energy conservation calculation of enterprise energy consumption process model based on S-invariant is put forward，as well as the energy efficiency of equipment and production is also discussed.The analysis shows that the presented methods will benefit to analyze and check the material balance，production overstock and production energy efficiency etc.existing in the practical energy consumption process.
