摘要
The article describes an experimental setup constructed for the verification of harmonic impedance (HI) measurement method in a real HV power grid. The setup is located in a 110 kV distribution substation in Poland. It includes voltage measurement circuits based on wideband resistive voltage dividers, multiple current measurement circuits, and distributed time synchronized data acquisition system. The whole setup is able to simultaneously sample 3 voltage and 12 current signals and record data on a dedicated data server. The details of the setup construction are presented. Some guidelines, based on experiences, are given on how to prepare such setup. Additionally a result of a preliminary experiment, in which the HI of the supply system was measured, is shown to confirm capabilities of the setup.
