Power Systems Conference

Clemson University

March 2005


History of distribution automation

History of Distribution Automation

  • The concept originated in the 70s

    • Use evolving computer and communications technology to improve operating performance

    • A few small pilot projects

  • Several major pilot projects in the 80s

  • Some large and many small projects in the 90s


Da at crossroads

DA at Crossroads

  • Difficult to justify using hard cost/benefit numbers

  • Business uncertainties due to deregulation and restructuring

  • Consolidation and focus on cutting operating expenses

  • Equipment reliability and obsolescence


Renewed interest in da

Renewed Interest in DA

  • Emergence of new technologies

  • New measuring devices and sensors

  • Powerful and refined communications equipment

  • Highly advanced computing equipment

  • Advanced power electronics

  • Advanced protection equipment


Drivers for advanced da

Drivers for Advanced DA

  • Enhancements in efficiency, reliability, and quality

  • Performance-based rates

  • Sensitive loads

  • Need to do more with less


Advanced automation devices

Advanced Automation Devices

  • Perform multiple tasks

    • Data logging

    • Control

    • Protection

    • Intelligence

  • Cost of these devices must be allocated to different functions


Value of reliability and quality

Value of Reliability and Quality

  • Different customers need different levels of reliability and quality

  • Power quality parks

  • Potential customers and their willingness to pay higher rates for premium service


Probabilistic nature of failures

Probabilistic Nature of Failures

  • Failures on distribution systems are random

  • Several factors increase the probability of failure

    • Trees, wind, lightning, animals

  • Map effects of these factors to identify feeders with higher probability of failure

  • Target these feeders for automation


Analysis tools

Analysis Tools

  • Real-time analysis for fast decisions

  • Distribution state estimator

  • Input data

    • System topology

    • Parameters of system components

    • Status of switches and breakers

    • Other measured data


Computational intelligence

Computational Intelligence

  • Central vs. Distributed

  • Data transmission bottlenecks

  • Distributed intelligence to alleviate bottlenecks

  • Hierarchical communication and computation

  • Balance between central and local


New sensors

New Sensors

  • Advances in sensor technology

  • New information

  • New applications

  • Lower cost with higher quantities


Asset management

Asset Management

  • Important for utilities

  • Enhance with advanced DA

  • Monitor condition

  • Manage real-time loading

  • Schedule maintenance

  • Increase utilization


Advanced communication technology

Advanced Communication Technology

  • Better communication equipment

    • Fiber optics

    • Radio

    • Satellite

  • Integrate the Internet

  • Appropriate media for the application


Conclusions

Conclusions

  • Distribution Automation is entering a new era

  • More robust and reliable equipment

  • Higher computing power

  • Higher emphasis on reliability

  • Utilities must consider DA as a planning option

  • Advanced planning and analysis tools are needed for DA implementation
