POWERLINE COMMUNICATIONS FOR ENABLING SMART GRID APPLICATIONS
Task ID: 1836.063
Prof. Brian L. EvansWireless Networking and Communications Group
Cockrell School of EngineeringThe University of Texas at Austin
Task Description:Improve powerline communication (PLC) bit rates for monitoring/controlling applications for residential and commercial energy uses
Anticipated Results: Adaptive methods and real-time prototypes to increase bit rates in PLC networks
Principal Investigator:Prof. Brian L. Evans, The University of Texas at Austin
Current Students (with expected graduation dates):Ms. Jing Lin Ph.D. (May 2014)Mr. Yousof Mortazavi Ph.D. (Dec. 2012)Mr. Marcel Nassar Ph.D. (Dec. 2012)Mr. Karl Nieman Ph.D. (May 2014)
Industrial Liaisons:Dr. Anand Dabak (TI), Mr. Leo Dehner (Freescale), Mr. Michael Dow (Freescale), Mr. Frank Liu (IBM) and Dr. Khurram Waheed (Freescale)
Transmission places 0-3 bits at each tone (frequency). At receiver, null tone carries 0
bits and only contains impulsive noise.
Our PLC Testbed• Quantify application performance vs. complexity tradeoffs
• Extend our real-time DSL testbed (deployed in field)• Integrate ideas from multiple narrowband PLC standards• Provide suite of user-configurable algorithms and system settings• Display statistics of communication performance
• 1x1 PLC testbed (completed)• Adaptive signal processing algorithms• Improved communication performance 2-3x on indoor power lines
• 2x2 PLC testbed (on-going)• Use one phase, neutral and ground• Goal: Improve communication performance by another 2x
• National Instruments (NI) controllers stream data
• NI cards generates/receives analog signals• Texas Instruments (TI) front end couples to
power line
• Real-time system runs transceiver algorithms
• Desktop PC running LabVIEW is used as an input and visualization tool to display important system parameters.
