The aim of this paper is the development of a theoretical model of medium-voltage (MV) cables in the frequency range of 25-200 kHz, which can be easily implemented in the Simulink environment. Two transmission-line configurations: 1) line-ground and 2) line-line were considered. The model requires the knowledge of the transmission channel parameters in the frequency domain. Thus, a characterization of MV cables in the two transmission-line configurations by means of experimental measurements was performed on commonly used MV cables, RG7H1R, of different sections, 95 mm2 and 185 mm2 with an aluminum core and copper shielded. To validate the model, a comparison between the attenuation constant alpha measured and the one simulated for both configurations under study was carried out.
"In this paper a complete model of MV power system for PLC communications, in the frequency domain, is presented in nthe case of a line to line configuration. The model requires the knowledge of the per unit length parameters of the transmission lines . Moreover the coupling system for the signal injection, the signal generator and the signal receiver are considered. "
[Show abstract][Hide abstract] ABSTRACT: In this paper a complete model of Medium Voltage (MV) power system for PLC communications, in the frequency domain, is presented. A simple and friendly Simulink ® software is used to develop the model. A distributed parameters MV cables model in line-line configuration is considered. Also the signal coupling networks with the generation and receiving systems are included. The performances of the complete PLC communication system are evaluated introducing the attenuation constant computed as ratio between the received and transmitted voltage signals. The signal losses produced by the complete system in the CENELEC frequency band and for different cable lengths are also considered.
[Show abstract][Hide abstract] ABSTRACT: In this paper a complete model of a power line communication (PLC) system on a Medium Voltage (MV) network is presented in the case of a line-ground configuration. A simple and friendly Simulink® software is used to develop the model. A distributed parameter MV cable model in line-ground configuration is considered together with the power transformers, the signal coupling networks and the receiving and transmitting line coupling interface of a ST7540 FSK powerline transceiver. The performances of the complete PLC communication system are evaluated for different line lengths by means of the attenuation computed as ratio between the received and transmitted voltage signals.

[Show abstract][Hide abstract] ABSTRACT: The aim of this paper is to develop a theoretical model of medium and high voltage cables used for the purpose of power line communication from the point of view of uncertainties. The equivalent circuit of power line communication cable is described along with its uncertainties. We have considered uncertainties since their propagation causes errors in modeling power line communication and in measuring the signal sent through the power line.
