Distribution Networking: Centralized Command and Control of the Distribution Grid

Although most of the public attention on Smart Grid architecture focuses on metering and consumer solutions, there is a third area that often gets overlooked: distribution. Distribution Networking provides two-way broadband wireless communications to connect substations and distribution grid devices to the utility’s head-end for significant operational benefits. The “always-on” capability of the distribution network not only enables the process automation of centralized SCADA and DMS applications but also enables on-demand management of the grid from centralized operators.

Distribution Applications

There are a variety of applications enabled by deploying distribution automation through a distribution network:

• Substation Automation
• Substation Video Monitoring
• Workforce Mobility
• SCADA
• Line Switch Automation
• Transformer Monitoring
• Capacitor Bank Control
• Line Voltage Monitoring
• Recloser Automation

Each of these Smart Grid solutions provides a distinct element of managing the distribution grid. The applications help utilities improve operational efficiency, system reliability, and asset utilization.

Operational Efficiency

• Enhanced utilization of generation sources (e.g., comprehensive power flow control from central and distributed sources)
• Reduced operations and maintenance (O&M) expenses
• Improves forecasting

System Reliability

• Remote monitoring and predictive maintenance
  • Reduction in the number and duration of outages
  • Reduction in the number of equipment failures
• Facilitated field repairs
• Improved customer satisfaction

Asset Utilization & Protection

• Grid load information for planning
• Optimized capital expenditure timing
• Improved safety
