Workshop on Applications for Powerline Communications, October 2008
Outline• Introduction• Market Overview• The Lavrion Pilot Project
– Topology Configuration– Networking Analysis– Photos– Measurements Example
• Conclusions and Questions
Slide 2
Introduction• Main Characteristics of smart grid
– Variety of generation options (Renewable sources)– New policies and pricing regimes– Quality and Reliability– Self healing (detect, analyze, respond, restore)– Network attack immunity
• Growing technology markets– Advanced Meters– Sensors, Monitors, Controllers– New Power Electronics Systems– Smart Equipment and Appliances
Slide 3
Market Overview (1/2)• Smart Grid Definition
– Digital technology to delivery segment
• Market Definition• Transmission vs.
Distribution vs. Grid– HV vs MV– Overlap in
technologies and vendors
– Little overlap in buyers
Slide 4
Market Overview (2/2)
Slide 5
• Line Infrastructure– Poles, Cables, Fittings that carry the power
• Station Infrastructure– Switches, Breakers, Transformers– Hardware, Software and services for design,
construction, operation, monitoring and control• Edge Infrastructure
– Connecting generation sources– Metering Electrical usage
Utility Efficiency Benefits from Smart Grid (1/2)Customer Interface• Automatic meter
reading• Service
connect/disconnect• 802.11 availability to
police/fire departments
System Protection• Fault recognition and
location
Load and Distributed Generation Management
• Demand side management
• Centralized dispatch of distributed generation
• Peak load shaving
Slide 6
Utility Efficiency Benefits from Smart Grid (2/2)Distribution Automation• Automation of line
reclosers and switches• VAR control
(capacitors, regulator, voltage metrics)
• Isolation of faults on single phases; rapid restoration
• Outage location and notification
Diagnostic Monitoring• Conductor temperature,
line voltage, status of line arrestors, fuses, line transformer
• Analyze line noise (EMI analysis)
• Real-time monitoring and predictive maintenance of Underground networks
• Identification of service-theft
Slide 7
MV/BPL Network• Typical Topology• Injector, Repeater
and Extractor• Second generation
MV/BPL units (all the above operations in one)– WiFi/WiMax
connection
Slide 8
GEN 2 MV/BPL Network• Easy
implementation (all in one)
• Improved Circuit Speed
• MIMO type antennas
• Protocols IEEE 802.11 a, b, g and n
• Multicast
