Development of an Experimental Scaled-Down Frequency Dependent Transmission Line Model

The penetration of power electronic based equipment in the grid has increased co-occurrence electromechanical and electromagnetic transients. Significant research efforts have been focused last decade to study these interactions. Frequency dependent transmission line models are indispensable understand such This paper describes a systematic procedure for development an experimental scaled-down 220 V frequency model 230 kV line. A reduced order lumped parameter using modal transformation is derived V. Clarke inverse transformations implemented specially designed 1- $\phi $ transformers. inductances realized amorphous cores.
