Desenvolvimento de Sistema de Gerenciamento, Supervisão, Controle e Aquisição de Dados da Microrrede Universitária do Campus do Pici – UFC

Abstract

For the safe and efficient operation of a microgrid (MR), the development and implementation of a supervisory system is of utmost importance. This work aims to present the development and implementation of a data acquisition, supervision and management system for an MR installed at the Federal University of Ceará. The three-phase MR has three single-phase photovoltaic (FV) generation subsystems, named SFV-1, SFV-2 e SFV-3 which operate connected to the grid, but have different operating characteristics: SFV-1 is capable of operating in on-grid and off-grid mode with the support of a battery system; SFV-2 has two strings of FV modules that can operate connected in series, parallel or just one string; and SFV-3 can be connected to any of the three phases of the grid, according to the operator's decision. To develop the supervision and management system, the Elipse Power software was used for SCADA, the SoMachine software for programming the MR's PLC and HMI, and the SQL Server software for creating the database. The Modbus TCP / IP protocol was used to communicate all the equipment used by the supervisory system. Tests were carried out to evaluate the performance of the management and SCADA functions in the supervision and operation of each FV subsystem, under different operating conditions of the MR. The graphic screens developed in SCADA have proved the proper functioning of the supervisory system and the record of the quantities collected in the database created for the MR.
