“…According to EN 50065-1 [33], the measured transmitted signal shall not exceed 122 dB µV with a peak detector with 200 Hz bandwidth from 95 kHz to 148.5 kHz. Besides, the voltage level of the transmitted signal can also refer to the measurement presented in [34], which was measured as 117 dB µV in a lab environment in the frequency range of 95-135 kHz. The average noise PSD in Italy in the range of 95-148.5 kHz presented in Figure 4 (of around 25 dB (µV) 2 /Hz), can be expressed as a noise level of 64.7 dB µV taking into account a resolution bandwidth of 200 Hz, and the measurement impedance of 50 Ω.…”

Currently, narrowband Power line communication (PLC) is considered an attractive communication system in smart grid environments for applications such as advanced metering infrastructure (AMI). In this paper, we will present a comprehensive comparison and analysis in time and frequency domain of noise measured in China and Italy. In addition, impulsive noise in these two countries are mainly analyzed and modeled using two probability based models, Middleton Class A (MCA) model and α stable distribution model. The results prove that noise measured in China is rich in impulsive noise, and can be modeled well by α stable distribution model, while noise measured in Italy has less impulsive noise, and can be better modeled by the MCA model.

Since the main distribution line faults can be securely identified as outlined in the first and second paper, this third paper presents the methodology of localizing the main distribution line fault when broadband over power lines (BPL) networks have already been deployed across the distribution power grids. The main issue of this paper is the detailed presentation of the main line localization methodology (MLFLM) as well as well as its performance assessment when measurement differences occur. The contribution of this paper, which is focused on the application of MLFLM, is double. First, the procedure, which is followed in order to create the database of faults and is used by MLFLM, is here analytically presented. This database is based on the application of the main distribution line fault identification percentage metric (MDLFI) to coupling reflection coefficients of all possible fault OV MV BPL topologies (modified OV MV BPL topologies). Second, the performance assessment of MLFLM is investigated with respect to the nature of the measurement differences and the location of main distribution line faults across the distribution power grid. Keywords: Smart Grid; Intelligent Energy Systems; Broadband over Power Lines (BPL) Networks; Power Line Communications (PLC); Faults; Fault Analysis; Fault Localization; Distribution Power Grids IntroductionA major advantage of the BPL networks is the fact that their development is simple and economically advantageous since their deployment is based on the already operating power grid infrastructure. As concerns the potential of the smart grid operation, BPL technology can act as either an autonomous communications system or a cooperative communications network that interoperates with other wired and wireless communications solutions in an integrated intelligent IP-based network environment. Anyway, the synergy of telecommunications solution under the aegis of the smart grid can support a myriad of smart grid applications [1]- [4].In the first paper [5], the determination of the channel attenuation and reflection coefficient of overhead medium-voltage (OV MV) BPL networks have been achieved by extending the original TM2 method, which is the core part of the top-down approach of the well-established hybrid method [3], [6]-[22] during the normal operation of OV MV

“…The MV PLC couplers require special components that withstand high differential voltages between the phases and ground, which make these devices more expensive and more difficult to implement than LV PLC couplers [3]. Some innovative MV PLC coupling solutions [105,106] have been proposed to replace commercial MV PLC couplers with less-expensive solutions by using a capacitive divider of voltage-detecting systems (VDS), which are usually already installed in the MV switchboards. Furthermore, an impedance matching circuit is designed between the transmitter and the MV capacitive divider to ensure maximum signal power transfer to the MV network.…”

Impedance mismatch that degrades signal power transfer and affects communication reliability is a major obstacle for power line communications (PLC). Impedance matching techniques can be designed to effectively compensate for the impedance mismatch between PLC modems and power line networks at a specific frequency or for a given frequency band. In this paper, we discuss the tradeoffs that need to be made when designing an effective impedance matching network. We also make a comprehensive review of previous state-of-the-art PLC impedance matching techniques and provide a useful classification of each technique. Finally, we discuss important issues (concerns) and provide suggestions for research directions deserving more attention. This review provides a useful guideline for researchers and manufacturers to quickly understand impedance matching principles and facilitate the design of an effective impedance matching coupler for PLC applications.
