Abstract:
Future electricity power network must be restructured to improve its e ciency
in order to provide all the consumers with
exible, cost e ective, reliable and
accessible power delivery. Power Line Communications (PLC) is a vital part of
Information and Communication Technologies (ICT) within the smart grid (SG).
This thesis presents the analysis and modeling of Low Voltage (LV) transmission
lines for Narrowband Power Line Communications (NB-PLC) by incorporating
the approach of transmission line (TL) theory and developing its Simulink model
followed by their results discussion. The thesis also presents the comprehensive
eld measurements based analysis which provides a generalized NB-PLC channel
model for LV access network in order to deploy Advanced Metering Infrastruc-
ture (AMI) within Lahore, Pakistan. This is the rst time, such kind of eld
measurements have been carried out in Pakistan. Selective sites for eld mea-
surements that include Gadda Stadium, Hafeez Center, Kot Lakhpat, Lahore
Cantt, Ghaziabad, Township, Wapda Town, Valencia Town and Defense Housing
Authority (Phase-V) were allocated by LESCO which took into account all classi -
cations of load types within Lahore city. The eld measurements of allocated sites
were performed in the residential (urban and rural), industrial and commercial
electricity consumers for the NB-PLC channel modeling of low voltage overhead
transmission lines (TLs). On the basis of extensive eld measurement results, the
average attenuation pro le and transfer functions (TFs) are presented. A Simulink
model is developed to validate the results obtained from eld measurements. The
analyses of measured and simulated results illustrate a close agreement of channel
TFs. This research work proposes an improved, more e cient, and more accurate
NB-PLC channel model especially for South Asian countries.
