The use of Wireless Sensor Networks (WSNs) are a
promising technology that can enhance various aspects of today’s
electric power systems, including generation, delivery, and
utilization, making them a vital component of the next-generation
electric power system, the smart grid. However, harsh and
complex electric-power-system environments pose great
challenges in the reliability of WSN communications in smartgrid
applications. This paper presents wireless sensors with
magnetic harvesting capabilities deployed along Underground
High Voltage Power Lines (UHVPL) to allow long-lasting
operation. The paper includes an overview of the communication
protocol that optimizes sensor node coordination in linear array
arrangements. Based on an optimal time synchronization
method, the wireless sensors can self-adjust the communication
timing in order to minimize the total power consumption. In
addition, the paper provides a description of a linear sensor
network under test, the results and discussions concerning
network reliability and power efficiency. |
