The paper is focused on communication signal transmission over specific topology of medium-voltage overhead power distribution lines with crosstalk between different power sections. The following parameters have been measured and modeled: channel frequency response, interference, background noise. On this basis we have set up models and computed the estimated data throughputs for narrowband Power...
This paper deals with design and development of a bidirectional coupling unit which is necessary to make measurements on the electrical low voltage distribution network for narrowband characterization of the power line channel. This coupling unit provide impedance matching and instruments protection. The designed coupling unit is verified by simulation and experimental measurement. Live measurements...
Weeeee propose Rogowski coils as coupling elements for Power Line Communication (PLC) in lithium-ion batteries for electric and hybrid vehicles. Current battery management systems use standard CAN busses for the communication between the battery control unit (BCU) and battery modules, which comprise lithium-ion cells. In contrast, in next-generation batteries the BCU should communicate with each lithium-ion...
The street light system, using a Power Line network, requires detailed knowledge about transmission medium, such as: transfer function, parasitic capacity, induced inductances and noise due to capacitive coupling between phases, in order to undertake a reliable master/slave communication. This paper proposes an innovative algorithm useful for a network dynamic configuration. It will allow to reduce...
In this work a characterization of a Wireless Power Transfer (WPT) system as a possible channel for data communication is presented. The frequency response of a real WPT system based on the principle of magnetic resonance coupling is simulated accurately using a lumped equivalent circuit model. The theoretical channel capacity of the channel is calculated as a function of the coupling coefficient...
This paper presents the specifications and the measurement results of conducted immunity requirements tests applied to coupling circuits designed, by authors, for the narrowband Power Line Communication channel measurement.

Distribution transformers are found in secondary substations, and connect to three phase low voltage lines that deliver electricity to points of supply. Electricity customers are charged for their consumption based in the measurements registered in meters present at the point of supply. (PLC) signal injection in key element in PLC signal PRIME is a narrowband PLC band, used by utilities to Power Line...
This is a discussion on the process of implementing a system for power line communication (PLC). A PLC system is desired as it will allow for phase identification of the load and the transmission of data from the load to a central receiver. There are two main processes in a PLC system: a communications protocol and signal coupling. The communications protocol involves the methodology employed for...
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...
It has been shown that power line communication (PLC) is a feasible method for data transmission between a low-voltage (LV) motor and a frequency converter through the power cable. In this paper, attenuation and noise power spectrum of the communication channel are analyzed. The analysis is based on a laboratory test setup, laboratory measurements, simulation models, and known power spectral density...
This paper presents the experimental interferences of 10 kV overhead power lines, which affect the preference of feeder terminal unit (FTU) based on power line communication (PLC). The representative interferences such as narrow band noise, switching operation, lightning disturbance and colored background noise are analyzed in detail. The characteristic and coupling ways of interferences are summarized...
Nowadays, the use of multiple-input multiple-output (MIMO) concepts is being investigated to improve performance of power line communication (PLC) systems, however few attentions have being put on how it can be applied to improve narrow-band technologies based upon single-carrier (SC) modulation. In this paper, a multiple-input single-output (MISO)-SC system for narrowband PLC is devised and the applicability...
The motor speed control is a typical industrial application where a feedback loop is used in order to transmit control information's to the controller using an extra cable dedicated for data transmission. In this paper we discuss the use of the feeder cable itself for communication instead of the extra cable by using the well known technology in domestic applications, the PLC "power line communication"...
In this paper a remote control equipment for monitoring and managing a street lighting system is presented. It is composed by a local control, realized by master boards located inside electrical panels and slave boards mounted on each lamppost, and by a remote control realized by a central unit for the remote communication with the local control system. The communication between master and slave boards...
In this paper we focus on the early history of using power lines for voice communications, beginning in 1918 and carrying the story forward to the early 1930s, when telephony using power lines had essentially established itself as a mature technology worldwide.
The access impedance of the power line channel is time variant. This feature of the power line channel is the main cause of impedance mismatching between the access impedance of the power line channel and the output impedance of the power line communication system and impedance mismatching lead to the problem of reducing the communication range. Therefore, it is very important to match between the...
In this paper, we developed a removable PLC module for electricity meter for AMR. The developed PLC module is compatible with Korea standard (KS) 4600-1 and consumes low power under 3 watts. We focused on suppressing noise which can be generated from a power supply, LC components, and several signal mismatches. Thus we can achieve long distance PLC communication with high robustness in terms of noise...
