Single-Phase Auto-Reclosure Studies: Some Basic Aspects on Main Elements Representation

This work presents some basic modeling aspects of SPAR implementation studies, including secondary arc model, line parameters, transmission equipment and interaction arc-grid. It is also suggested the inclusion of some basic criteria in successful SPAR in the optimization of transmission line design. For instance: - Line bundle configuration, line reactive compensation and some non-conventional procedures may play an important role in the SPAR success. - For very long lines, e.g. with lengths of the order of 2500 km, without intermediate substations, it is possible, with some non-conventional solutions, to assure high probability of successful SPAR.
