Behavior of MV Lines from 2.5 to 100 kHz

The large penetration of distributed generation requires accurate over-head line and cable models in a frequency range much wider than the classical interval, 0-2.5 kHz, used for traditional harmonic and interharmonic penetration studies. In this paper, the results obtained in previous papers by the same authors on the behavior of both over-head and cable MV lines in the frequency range from 0 to 100 kHz are reported. Reference is made to models based on the classical. line equivalent circuits of different complexities. The results of the different models are illustrated in terms of output terminal impedance magnitude; a very simple case study is also presented.
