Attenuation Characteristics

Signal transmission attenuation characteristics of low voltage power distribution network is an important factor must be considered by the power line communication system design. The effects of power line network on the power line communication channel attenuation are studied, including cable cross-sectional area, length and T network structure. With the experimental and simulation results, the relationship between low voltage power line cable length, the network structure and the power line communication channel attenuation is analyzed.

Power Line Communication

The transmission of data signals over power lines is a very promising technique for delivering indoor broadband communication services. However, since power grids were originally designed for high-voltage low-frequency signal transmission, there is a frequency mismatch between the power grid and high-frequency data signals. This mismatch poses a challenge to deploying power lines as a communication channel. Although, studies and researches conducted in several countries have made transmission of data over power lines possible, the behaviour and properties of the power grid cannot be generalised. Hence, the need for in-depth experiment and measurement on the suitability and capability of the Nigerian power grid for data transmission is crucial for proper characterising and modelling of the power line communication (PLC) channel. In this paper, we present experimental measurements and results of the effects of frequency variations on the attenuation experienced by broadband high-speed data signals transmitted over the Nigerian indoor power line network.

Attenuation Characteristics

When the low-voltage power line is used as a communication line, the channel characteristics have an important impact on the communication quality. In this paper, power distribution networks are divided into three categories. The paper selects a typical power distribution area and uses a rigorous method to test channel attenuation characteristics of the narrowband (50 kHz~500 kHz) carrier. Base on the measurement data, carrier attenuation characteristics are summarized. The measuring method used in the paper and the conclusions of this paper would play a guiding role on the research of the power line carrier communication.
