Abstract

Power line communication (PLC) technology is exploited worldwide for automatic meter reading on low-voltage networks. On the contrary, it is not used at medium voltage (MV) level, where it requires dedicated and costly PLC couplers. To face this issue, in previous works the authors investigated the possibility of reducing costs by coupling the signal by means of elements already installed in MV networks. A patented solution was based on the exploitation of capacitive dividers of voltage detective systems (VDSs) normally installed in MV switchgears of distribution network's substations. This paper investigates the use of capacitive dividers embedded in commercial separable connector of MV cables heads, instead. In comparison with VDSs, cable heads voltage dividers have different characteristics; thus an ad-hoc characterization and design of PLC coupling system is presented and discussed. Firstly, impedance measurements are performed to characterize cable heads behavior in the frequency range of interest. An equivalent circuit model is obtained and used to design an electronic interface card for signal coupling. Simulations and experimental tests are performed in FCC above CENELEC frequency band, to analyze channel frequency response and transmission performances, in terms of success rate and SNR. The results testify the proposed coupling solution feasibility.

Abstract

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 enviroment. 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 [mm.sup.2] and 185 [mm.sup.2] 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. Index Terms--Attenuation constant, medium-voltage (MV) cables, power-line communication (PLC), transmission line.

Abstract

The aim of this paper is to illustrate the development of a theoretical and experimental study on the characterization of medium voltage (MV) cables in the frequency range 25-200 kHz. Two transmission line configurations, line-ground and line-line, were considered in order to evaluate the main parameters, such as the characteristic impedance and the attenuation constant [alpha]. A simplified model of the line-ground configuration is proposed which allows one to evaluate the characteristic impedance and the attenuation constant by means of geometrical dimensions. The model was verified by experimental measurements on commonly used MV cables, RG7HIR, with an aluminium core of different sections, 95 [mm.sup.2] and 185 [mm.sup.2]. Moreover, the experimental tests were carried out for the line-line configuration. Index Terms--Attenuation constant, characteristic impedance, medium voltage cables, power line communication, power system communication.
