Power line model for testing transient response of PMU

Abstract

In the “Relay Protection” laboratory of TU-Sofia power line physical model was adapted for testing of PMU, with target to demonstrate the students PMU and multifunctional Intelligent Electronic Device (IED) functionality. Another target was to improve the student’s skills to make oscilloscope records of signals and to compare with IED/PMU obtained data. The model scheme general characteristics and the approach of PMU function demonstration are presented in the paper.
