Robust estimates for validation performance indexes of electric network models

The validation of an electric traction network simulator is addressed by selecting the testing conditions and considering three performance indexes, which evaluate both simply amplitude and other curve features. A common interpretation scale is proposed to verify the agreement between them. Moreover, since the most complex cannot be fully used without a graphical representation of its output, this is simplified, in order to conclude the validation with an estimate of accuracy that is as close as possible to the classical declaration that accompanies measuring instrument.
