Performance evaluation of G3-PLC over distribution transformers in Indian context

The past few years have witnessed a tremendous development in Power-Line Communications (PLC) technology such as G3-PLC with existing power-lines for high speed data communication across High voltage (HV), Medium Voltage (MV) and Low Voltage (LV) transmission/distribution networks based Smart Grid (SG) applications. As power-lines were not originally intended for conveying high frequency signals, and any communication over these lines would be exposed to severe adversarial factors, such as interference, impulsive and phase noise. G3-PLC technology also elucidates the importance of employing robust modulation schemes across distribution-transformers and motivates research in this direction. Indeed, the aim of the paper is to investigate G3-PLC channel measurements through MV/ LV distribution-transformers by implementing experimental tests to analyse the signal-to-noise ratio (SNR), Bit Error Rate (BER) and Packet Error Rate (PER) performance of DBPSK, DQPSK and ROBO (Robust) modulation schemes over multipath PLC channels in Indian context.
