摘要

Not only that tremendously increased employmentrnof power electronics in the energy production, transfer, andrnconsumption enables a sustainable future, it undoubtedly bringsrnmajor energy savings and stimulating improvements in people’srnquality of life. But not for “free”. This trend is considerablyrnchanging the nature of the sources and the loads in the electricalrngrid, altering their mild properties, and inflicting low-frequencyrndynamic interactions that did not exist in the conventionalrnpower system before. To be able to understand, analyze, design,rnand dynamically control the existing and future power systems,rnit is unarguably required to develop concepts and tools thatrnoffer better insights into the system-level behavior and stabilityrnof the grid. This paper presents the impedance measurementrnunit that can undoubtedly address some of the listed needs byrncharacterizing in-situ source and load impedances of the subrntransmission medium-voltage networks (up to 69 kV). Inrnaddition to describing the design, this paper shows thernexperimental results obtained with the impedance measurementrnunit prototype built for 4.16 kV, capable of characterizingrnmedium-voltage distribution systems of up to 2.2 MVA.
