seen from the ASCII textbox, the signal is received correctly
without any errors.
In the literature, there are not many papers on narrowband
MV PLC, and few papers present measurements results on a
real MV network [9], [16] and [17]. In [9], a PLC measuring
campaign between two substations connected by a 3-km cable
line was performed. The experimental results show selective be-
havior, in the range 70–75 kHz, similar to that of Fig. 16 but with
a least attenuation of 20 dB. The different attenuation in Fig. 16
can be justified to a different line length and the presence of an
amplifier, as shown in Fig. 14. Similar results were found in [16]
and [17], where the feasibility of PLC signal transmission on a
real MV network is also shown.

V. CONCLUSION
This paper presents the complete model of a PLC system in
the case of an MV network. The model was easily developed by
means of Simulink. In order to validate the developed model, ex-
perimental tests on the MV network on Favignana Island were
carried out. The transmission was performed between two trans-
former substations in the presence of the mains voltage (i.e.,
24 kV). The experimental measurements validate the simulation
results, thus validating the developed model which can be used
to evaluate the performances of an MV transmission channel.

ACKNOWLEDGMENT
The authors would like to thank SEA spa, who allowed them
to carry out experimental tests on the MV power network on the
Island of Favignana.
