Integrated electromechanical simulation of traction systems: Relevant factors for the analysis and estimation of energy efficiency

Electromechanical analysis and simulation of traction systems are required to estimate the power consumption, to size the power system and to optimize system parameters for energy saving. The number of variables and parameters (mechanical and electrical) is huge, affected by various degrees of uncertainty. An integrated simulation approach is presented, where the requisites for the correct evaluation of regenerative capability are considered.
