RESUMO

This is a descriptive study concerning the modeling technique applying object-oriented models for a communication interface among the equipments in the field of an electric substation. The standard architecture UCA - Utility Communications Architecture and GOMSFE - Generic Object Models for Substation &Feeder Equipment are used, allowing the reduction of the number of protocols in the different equipment s in the yard. This work also addresses the characteristics and the requisites of an automated substation, in what this new modeling technology is about and its applications for the electric power systems. The different models used for the functions of protection, measurement, control, etc. of an Electric Substation are considered, including the new equipment which carry the information from sensors and actuators in the field to their respective SCADA - Supervisory Control &Data Acquisition - system. The performance of the substation is enhanced by new functions as “voting” in protection relays, “bus blocking” in busbars, "load shedding" in load dispatch. Finally the modeling of the communication functions of the field equipments in the substation Bateias, of Copel - Companhia Paranaense de Energia Elétrica is carried out. The equipment s are the ones found in the Brazilian electric market and the reference schemes are from the bibliography. It is shown that the modeling is effective for the communication among the equipment s in the field of an electric substation, and that it is possible to standardize the different protocols employed there. Consequently the compatibility among the equipment s from different manufacturers occurs, and also the reduction of the costs of implementation, programming and personnel training within the substation.
