1 MedFasee Project Development and Applications Department of Electrical Engineering Federal University of Santa Catarina (UFSC) 1

2 The Federal University of Santa Catarina MedFasee Project: First Prototype (2003) The main goals were: Development of a Synchronized Phasor Measurement System prototype Applications for power system monitoring and analysis Project sponsored by: Brazilian Government (Finep/CT-Energ) Reason Tecnologia S.A. ( First Prototype 3 PMUs installed in Southern Brazil universities Three-phase low voltage Data transmission using Internet The PDC is located in the Federal University of Santa Catarina 2

3 MedFasee Project Current configuration of the National Synchronized Phasor Measurement System (SPMS MedFasee BT) PMUs are installed in 23 universities, covering the 5 geographical regions Virtual Private Network over Internet for communication between PMU and PDC (LabPlan/UFSC) PDC PMU 3
