Input-output-based Life Cycle Energy Inventories and Modeling in Electric Trains with Traction Induction Motors Fed from

In this paper life-cycle energy inventories and modeling of electric trains with traction induction motors fed from d.c. line on basis of input-output data study are presented. The data- Life Cycle Analysis (LCA) relationship is investigated, and the importance and role of data in LCA is reviewed. There are taken into account the electric trains with traction induction motors fed from d.c. line, not simply in terms of technico-economical growth, but also as achievements of the Sustainable Development. The paper presents data regarding the materials and energies in a lateral wall manufacturing process and assess an exergetic analysis on basis of mathematical models and structural diagrams of the traction induction motor, the voltage-source inverter and line-side converter used on the trains fed from d.c. line. The overall structural diagram construction for the principle schemes corresponding to modern electric trains fed from d.c. line is also presented. Through its rational and meaningful approach, the Life Cycle Energy Analysis, and particularly an Energy Inventory will help improve and optimize the design, manufacture, operation and final equipments deconstruction of a transportation system..
