A new software tool for evaluating the electric service quality of a power bus system for automotive applications

الملخص EN

A complex modular technique based on a full library of modeling of automotive components implemented on SABER and MATLAB environment and aided by a software platform that manage all the developed routines in a unique framework is proposed to evaluate the electric service quality of a power bus system for automotive applications.

The suggested technique gives the steady-state and the transient analysis of the overall on-board electrical system and by means of a multicriteria analysis evaluates the electric service quality index of the analyzed power-buses.

This index takes in account the following items: state of charge of the batteries in a drive cycle, bus voltage profile and voltage sags and dips and power bus efficiency.

Thanks to this tool it is possible to compare different power bus architectures under the aspect of the electrical quality obtaining interesting information about the performance of the examined power buses and their adaptability to the requests of the operative conditions.

This tool represents a suitable decision support technique during the phase of the design of the architecture of a power bus for automotive application.

In the paper after a full analysis of the proposed tool some numerical results are presented in order to prove the goodness of the proposal.
