RESUMO:

The present work has the objective of proposing a new topology of medium voltage distribution network of the UFRN Central Campus from the start of operation of the 69 kV substation at the Federal University of Rio Grande do Norte (UFRN). In 2016, UFRN's electricity supply system ceased to be two 13.8 kV inputs and was supplied through a subtransmission line and a 69 / 13.8 kV substation. This study will consider the current medium voltage distribution network, collecting physical information from this network, such as division and the path of the 13.8 kV feed circuits of the UFRN internal distribution system; quantity, power and type of current electricity substations; lifting of the maneuver equipment and protection of the 13.8 kV network. From this survey, we will analyze, from the new configurations, the magnitudes of the electric network, among which: power flow in the lines and voltage in the buses of the system, considering the scenario with the substation of 69 kV in operation. This analysis intends to propose the best technical situation of the medium voltage distribution network (always taking into account what is already done in the Central Campus), with less technical losses, distribution of protection equipment and maneuver, with the new routes of the feeder circuits in order to energize all UFRN loads. In the case of maintenance or operation that needs to deenergize a feeder 13.8 kV, the study intends to present possibilities of modifications of the network topology, to allow each sector of the Central Campus to be supplied by another feeder circuit, without not interrupting the power supply maintaining system security and selectivity.
