Incorporating information and communication technologies into grid systems provides advanced capabilitiesx000D
for remote, and real-time monitoring and control of devices. In smart grid systems, wireless relays are used inx000D
the data collection for fault detection and power quality analysis. When wireless base stations are closer to highx000D
voltage transmission lines, the signals from the base stations impact the monitoring of the lines as impulsivex000D
noise. With the growing number of cellular base stations mainly in urban areas, this impulsive noise becomes ax000D
problem causing the loss of data integrity when wirelessly transmitted. In this project, we will study thisx000D
problem to quantify the loss of data and to determine the number of additional relays required to maintain thex000D
same data quality in this noisy environment. This will help optimize the relay system operations (number ofx000D
relays and locations) when excessive noise is detected in power lines.x000D
In particular, a hybrid network architecture comprised of wireless sensor networks and cellular network will bex000D
considered to monitor the high voltage transmission lines in the urban and suburban areas. Corona noise is onex000D
of the sources of electromagnetic interference in such lines. We will first characterize the wireless channel withx000D
impulsive Corona noise near cellular base stations; then formulate and solve the problem of finding thex000D
optimum number of relays/sensors in a Zigbee-based linear and non-linear wireless sensor networks. Goal is tox000D
develop a matrix with the expected number of additional relays and their locations needed to maintain the samex000D
data quality for various intensity of noise level. The effects of physical and MAC layer parameters on thex000D
monitoring performance will also be quantified and included in the matrix to be used as operational guidelinesx000D
in the relay system.
