1. 1 Meeting of Red Team – Purple Team Ship Design Process and Model Development Arlington VA August 20, 2010

2. 2 Agenda Introduction to ESRDC Ship Design Process and Model Development – S. Dale Status report on Coordination of database for components and systems - R. Hovsapian MVDC/MVAC architecture and model status – M. Steurer HFAC architecture and model status – R. Hebner Focus groups for component model development – R. Dougal Purple team ESRDC recommended next steps – E. Zivi ESRDC VV&A process development

3. 3 Red Team (Steurer) White Team (Dougal) Blue Team (Hebner) HFAC Common MVAC, MVDC, HFAC Architectures Model Architectures In MATLAB/SIMULINK SABRE and PSCAD Pose and Solve a few Interesting Test Problems Use Test Problems for Modeling Validation Baseline Coordination Team (Hovsapian) Purple Team (Zivi, Chrys) Available to the Navy and the ship building community MVDCMVAC Coordinated Effort

4. 4 Systematic Approach Notional AC baseline information from “Notional DDX” MVAC Baseline (60 Hz) MVDC Baseline HFAC Baseline (>60 Hz) Will provide a suite of traceable baseline ship power system models for exploring the processes for comparing system architecture technologies, model validation, cross-tool validation, model fidelity reduction, uncertainty analysis, etc. Source: Syntek - IPS Electrical Plant One-Line Diagram Functional, generic, notional surface combatant baseline

5. 5 Generic Electrical One-Line M. H. Ali, R. A. Dougal, M. Steurer, L. Graber, J. Ciezki, M. Andrus, D. Infante, R. E. Hebner, A.
