The power line communication (PLC) channel has been a transmission medium that enables to transfer high-speed digital data through the classical electrical wires. Channel characteristics of power lines are very important for communications systems design. In order to get the suitable model for power line communications analysis and improve the PLC communication quality, researchers do lots of study about the PLC channel characterizations based on actual measurement and theoretical analysis. This paper reviews the conclusions of recent studies, summaries the characteristics of PLC channel for medium voltage power lines and low voltage power lines. The further research is also put forward.

Conducted Emi

Various kinds of household appliances have been widely deployed in the low-voltage grid. They inject conducted noise into the power line system, which may cause a detrimental effect on the Power-line Communications (PLC) channel. This paper examines a new measurement method of conducted Electromagnetic Interference (EMI) on the PLC channel. The proposed method is to facilitate the noise characteristic research, which overcomes the potential difficulties when the measurement is performed according to CISPR 16-2-1. In particular, taking the hairdryer as an example, the conducted noises when the motor is deemed as the noise source are measured by employing the presented method. Moreover, this paper also analyzes the conducted noise of the hairdryer both in the time domain and in the frequency domain, and interprets the noise generating mechanisms with the working principle of the motor in detail. The central issue in all these studies is to research the conducted electromagnetic noise characteristics on the PLC channel.

Distributed Energy Resources might have a severe influence on Power Line Communications, as they can generate interfering signals and high frequency emissions or supraharmonics that may cause loss of metering and control data. In this paper, the influence of various energy resources on Narrowband Power Line Communications is described and analyzed through several test measurements performed in a real microgrid. Accordingly, the paper describes the effects on smart metering communications through MAC layer analysis. Results show that the commutation frequency of inverters and the presence of battery chargers are remarkable sources of disturbance in low voltage distribution networks. In this sense, the results presented can contribute to efforts towards standardization and normative of emissions at higher frequencies higher, such as CENELEC EN 50160 and IEC/TS 62749.
