A Model for 10kV Overhead Power Line Communication Channel
نویسندگان
چکیده
In order to achieve reliable and high-speed 10kV power line carrier communications, it is necessary to study the characteristics of channel. Based on the multi-conductor transmission line theory, the chain matrix channel model is established. A lumped parameter model of distribution transformer is proposed from impedance measurement in the frequency range 50-500kHz. The terminal voltages and currents of whole network are derived, which reveals the causes of frequency selective fading. The simulation results are compared and analyzed between different signal frequencies and propagation paths, based on a simplified model of distribution network.

متن کاملA Suitable Coding Scheme for Broadband Power-line Communication
This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the thi...

In this paper, genetic algorithm-based approach for transient analysis of single transmission line connected to arrester is proposed. In this approach, the lightning channel striking the overhead line is first represented by a current source and this source is truncated by a finite set of frequency harmonies in time domain. Norton equivalent circuit viewed across arrester is then computed by me...

متن کاملMeasurement and simulation framework for throughput evaluation of narrowband power line communication links in low-voltage grids
High-data-rate narrowband Power Line Communication (PLC) is a prominent candidate for smart grid communications in the low-voltage grid at low operational costs. However, the power-line channel is fairly harsh in terms of time-variance, frequency selectivity, and observable impulsive and narrowband noise sources. These unpredictable phenomena motivate selective measurement campaigns in addition...
