Passive Power Line Communication Filter Design and Benchmarking Using Scattering Parameters

چکیده
NB-PLC (narrowband power line communication) is a method of data communication that involves superimposing relatively high-frequency signal (9 kHz to 500 kHz), which contains data, onto the grid’s low frequency (50 60 Hz) signal. While using existing grid as transmission medium convenient, was not designed for this purpose, leading challenges such conducted emissions and infrastructure limitations. To overcome these technical challenges, passive filters are necessary. This article presents design, simulation (using scattering parameters), evaluation an filter by comparing it commercially available filters. Our proposed design benchmarking methods enable accurate prediction filter’s behavior in field conditions. After our with filters, we observed exhibits superior characteristics. Specifically, has best insertion loss versus frequency, achieved three times higher attenuation at 50 (−130 dB) compared (−40 dB), consumption 0.6 W, comparable most power-efficient commercial (0.5 W). Additionally, second input output impedance 3.6 Ω within range 35–95 kHz.

The article describes a way of evaluating the power line channel frequency response and input impedance by means of the linear time-invariant (LTI) power line generator. Two possible methods are introduced for the calculation of primary parameters: the first method depends on the physical realization and physical dimension of the cable, and the second method is derived from the data provided by...

Accurate power line channel models are an essential asset for the development of advanced power line communication systems. A physically based power line communication channel model is derived. Elements within a power line network, e.g. line discontinuities, branches, and loads, are modelled as IIR-filters. The transfer function of the overall channel is calculated by concatenating the transfer...
