  1. Power Assessment & Distribution 2-5 May 2005 Joint Service Power Expo Tampa, Florida H. Scott Coombe, P.E. harold.coombe@us.army.mil Army Power Division Power Generation Branch Fort Belvoir, VA

  2. Topics • Power Generation Branch Overview • Power Assessment Mission • Power Assessment Tools • Questions & Feedback

  3. CERDEC Mission Statements Army Power Division “To Conduct Research, Development and Engineering leading to the most cost-effective power, energy and environmental technologies to support army portable and mobile applications in the field” Power Generation Branch “To conduct Research, Development, and Engineering activities leading to the advancement of Power Generation Systems to Support Unique Mission Requirements”

  4. Power Assessment Mission Database Develop, Update, and Maintain Shelter Power Data Model Power Grid Performance Validate Contractor Estimates For Power Consulting Services for Power Applications Measure Power Data During System Operation Assess Power Needs For Army Systems Assessment Reporting Data Collection/Evaluation Revised TOC Power & Distribution Layouts 3

  5. Power Assessment Mission Management / Funding… Execution… Department of Defense Project Manager Mobile Electric Power + Customer

  6. Power Assessment Objectives: • Identify power generation & distribution equipment needs • Optimize selection and application of power and distribution equipment Benefits: • Maintainability (MTTR) • Reliability (MTBF) • Availability • Fuel Consumption • Size & Weight • COST & LOGISTICS BURDEN

  7. V CORPS SBCT XVIII Airborne Corps Power Assessments – A Sampling Large Complex Power Grids are becoming more common!

  8. Power Assessment – Discussion Topics • Match power system to load - “right sizing” • Wetstacking occurs at light loads • Centralized Power vs. Power Islands • Military vs. Commercial assets • Power Distribution vs. Power Connection • Redundancy / Reliability needs vary by unit • Grid Design can have dramatic impact on transportability • Heating & Cooling loads are single largest loads in most tactical systems

  9. Introduction to Autodise AutoDISE 2.0 www.autodise.net What is it? How can it help me? …Web accessible, secure, fully functional application

  10. Introduction to Autodise A Web-Based Computer Model for Design, Simulation, and Optimization of Tactical Power Grids What is Autodise? • Features: • Windows-like Grahical User Interface • Automatic connection and phase balancing between generator(s) and Load(s) • Generates Reports • Grid Layout • Equipment Inventory • Power Analysis • Statistical Analysis • Import TOE / MTOE from Excel How can it help me? • Benefits: • Improves reliability of grid • Enables quicker power grid design • Calculates estimated fuel consumption • Calculates probability of full power availability

  11. Layout View • AutoDISE is more than a Drawing Tool… • …It is a Simulation Tool

  12. Analysis Report Load Imbalance Probability of having adequate power available Fuel Consumption

  13. Inventory Report Sort by any column heading

  14. On-going Improvements to Autodise • Improve speed and performance – PC Version • Autosave feature • Improve data manipulation for consumers, DC converters, and generators • Built-in Training Course • More detailed statistical analysis • Topographic underlays • Computations of line loss (voltage) over distance • Show power layout diagrams inside tents and shelters. AutoDISE Version 2.1

  15. Closing Comments Power Assessments are an increasingly useful method to optimize tactical power grids PM-MEP & CERDEC are available to help Autodise is available for use now! Check it out at www.autodise.net using the interim username “mep” and password “mep” Come see us in booth #301 !
