  1. AN NSF / ONR FUNDEDPROJECT ON THE USE OF MICROMECHANICAL MACHINES IN A POWER CIRCUIT BREAKER G. HeydtArizona State UniversityTempe, AZ

  2. Project Team • D. James (MSEE - Power) • Rahim Kasim (PhD - MEMS) • Neil Shah (MSEE - Power) • M. Sofixo (MSIE - Reliability) • E. Gel (IE - Reliability) • G. Heydt (EE - Power) • N. Hubele (IE - Control) • G. Karady (EE - Power) • B. Kim (EE - MEMS)

  3. Main Concept in the Project The main concept of the project is to use microelectromechanical switches in a series / parallel configuration as a power distribution circuit breaker

  4. Potential Advantages • Better characterization of distribution system performance (including power quality) • Identification of the proper tradeoff between investment and service • Optimization of the investment in distribution equipment • Improved power quality • Improved reliability • Improved hardness to power quality problems, less vulnerability.

  5. Side View of a MEMS Switch

  6. Basic Concept

  7. Analysis of the Failure Process: Represented as a Markov Process G. T. Heydt, D. S. James, E. S. Gel, M. M. Albu, N. F. Hubele, “The Reliability Analysis of High Power Switches Composed of Series and Parallel Branches” IEEE - PES General Meeting 2003

  8. Hierarchical Block Simulations in PSpice

  9. Bypass Using Semiconductor Switches

  10. Where We Are Going Where We Are • Pspice simulations • Educational module development • Custom MEMS manufacture • Configuration for AC vs DC switch *Demonstration*Reliability calculations*Testing device*Correlation of lab results with theory*Testing educational modules*Commercial ventures*Reflecting sponsors’ interests

  11. Acknowledgements • To my colleagues and students who are working on the project • To Dr. Momoh at the NSF • To the staff at ONR for their input

  12. Project Component in Education • Graduate research assistant training • An educational module on distribution engineering to be placed on the Internet • A planned workshop focusing on innovative designs in power distribution -- to be offered for practicing engineers, researchers, graduate students, and undergraduates. • Integration of distribution engineering topics into undergraduate coursework • Utilization of a tri-university network for the dissemination of course materials on distribution engineering • Development of an educational module to be integrated into the graduate courses in both industrial and electrical engineering highlighting optimization and stochastic modeling in distribution networks
