“…As usually done in BPL transmission, a hybrid model is employed to examine the behavior of BPL transmission channels installed on BPL multiconductor transmission line (MTL) structures [14,15,[24][25][26][27][28][29][30][31]. This hybrid model follows (i) a bottomup approach consisting of an appropriate combination of similarity transformations and MTL theory to determine the propagation constant and the characteristic impedance of the modes supported [24][25][26][27][28][29][30][31][32][33][34][35][36][37] and (ii) a top-down approach based on cascaded matrices of two-port network modulesthe T-matrix (TM) method-to determine the end-to-end attenuation of BPL channel connections [10,15,16,22,24,26,28,30,34,37,38]. The influence of factors, such as the overhead HV power grid type (150 kV, 275 kV, or 400 kV and single-or double-circuit), the coupling scheme applied, the physical properties of the cables used, the MTL configuration, the end-to-end distance, and the number and the electrical length encountered along the end-toend HV/BPL signal propagation, is investigated based on numerical results concerning simulated overhead HV/BPL topologies.…”

This paper considers broadband signal transmission and statistical performance properties of high-voltage/broadband over power lines (HV/BPL) channels associated with overhead power transmission. The overhead HV/BPL transmission channel is investigated with regard to its spectral behavior, its end-to-end signal attenuation, and its statistical performance metrics. It is found that the above features depend critically on the frequency, the overhead HV power grid type (150 kV, 275 kV, or 400 kV and single-or double-circuit), the coupling scheme applied, the physical properties of the cables used, the MTL configuration, and the type of branches existing along the end-to-end BPL signal propagation. The contribution of this paper is threefold. First, the significant broadband transmission potential of overhead HV lines is revealed. The results demonstrate that, regardless of overhead HV power grid type, the overhead HV grid is a potentially excellent communications medium, offering low-loss characteristics, flat-fading features, and low multipath dispersion over a 25 km repeater span well beyond 100 MHz. Second, regarding the statistical properties of various overhead HV/BPL transmission channels, two fundamental correlations of several wireline systems, for example, coaxial cables and xDSL, are also validated in the case of overhead HV/BPL transmission channels, namely, (i) end-toend channel attenuation in relation with root-mean-square delay spread (RMS-DS) and (ii) coherence bandwidth (CB) in relation with RMS-DS. Third, fitting the numerical results and other field trial measurements, two regression distributions suitable for each fundamental correlation are proposed.

“…In order to validate the accuracy of TM2 method and simplify the following analysis without affecting its generality, the branching cables are assumed identical to the transmission cables and the interconnections between the transmission and branch conductors are fully activated. With reference to Figure 2 To compare the proposed TM2 method with other established methods [1,2,24,25,32,47,77,78] and simultaneously examine the end-to-end channel attenuation behavior for different overhead HV/BPL types and topologies, in Figures 3(a), 3(d), 3(g), and 3(j), the endto-end channel attenuation from A to B is plotted with respect to frequency for the propagation of CM 150 kV for the aforementioned four indicative topologies, respectively, applying the proposed TM2 method, the TM method [1,2,24,25], and the Multipath-Echo Based (MEB) method [32,69,77,78]. In Figures 3(b), 3(e), 3(h), and 3(k), similar plots are drawn for the propagation of CM 275 kV and in Figures 3(c), 3(f), 3(i), and 3(l) for CM 400 kV .…”

The need of bridging the digital gap between underdeveloped/developed areas and promoting smart grid (SG) networks urges the deployment of broadband over power lines (BPL) systems and their further integration. The contribution of this paper is fourfold. First, based on the well-established hybrid model of (Lazaropoulos and Cottis 2009 and the generic multidimensional network analysis tool presented in , Sartenaer 2004, Sartenaer and Delogne 2006, 2001) an exact multidimensional chain scattering matrix method, which is suitable for overhead high-voltage/broadband over power lines (HV/BPL) networks, is proposed and is evaluated against other theoretical and experimental proven models. Second, the proposed method investigates the overhead HV/BPL transmission grids (overhead 150 kV single-circuit, 275 kV double-circuit, and 400 kV double-circuit multiconductor structures) with regard to their end-to-end signal attenuation. It is found that the above features depend drastically on the overhead power grid type, the frequency, the MTL configuration, the physical properties of the cables used, the end-to-end distance, and the number, the length, and the terminations of the branches encountered along the end-toend BPL signal propagation. Third, the impact of the multiplicity of the branches at the same junction in overhead HV grids is first examined. Based on the inherent long-branch structure and the quasi-static behavior of single/multiple branches with matched terminations of overhead HV grid, a simple approach suitable for overhead HV/BPL channel estimation is presented. Fourth, identifying the similar characteristics among different overhead HV/BPL configurations, an additional step towards the common overhead HV/BPL analysis is demonstrated; the entire overhead HV/BPL grid may be examined under a common PHY framework regardless of the overhead HV/BPL grid type examined. Finally, apart from the presentation of broadband transmission potential of the entire overhead transmission power grid, a consequence of this paper is that it helps towards: (i) the better broadband monitoring and management of overhead HV transmission power grids in an interactive SG network; and (ii) the intraoperability/interoperability of overhead HV/BPL systems under the aegis of a unified transmission/distribution SG power network.

Dual Use of Power Lines for Data Communications in a System-On-Chip Environment

Abstract-We propose to use power pins to simultaneously carry data signals while delivering its power. A direct superposition of a data signal on a power pin would fail due to an inherent high noise level on power lines and precludes the possibility for multiple data channels. To address the problem, we suggest adoption of the UWB (Ultra Wideband) and direct sequence-code division multiple access (DS-CDMA) communication technologies. Because of the wide bandwidth, a UWB signal can reduce its average power level practically to the noise level. The DS-CDMA further mitigates the noise and allows multiple data channels to share inter-connected power lines. We studied the feasibility of the proposed scheme through SPICE simulations and present the simulation results.
