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

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 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 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 Generic Electrical One-Line M. H. Ali, R. A. Dougal, M. Steurer, L. Graber, J. Ciezki, M. Andrus, D. Infante, R. E. Hebner, A. Ouroua, and Damon Weeks, “Guidelines for the Specification of Models to be Used in Design- Oriented Simulations”, accepted for presentation at GCMS, Ottawa, Canada, July 2010 Starboard Power Distribution Bus Stern Cross-hull Disconnect Bow Cross-hull Disconnect Zonal Ship’s Service Loads Port Power Distribution Bus Special Load Auxilary PGM 2 Main PGM 2 Main PGM 1 Auxilary PGM 1 Starboard PM VSD Port PM PGM = Power Generation Module VSD = Variable Speed Drive High Power Pulsed Load Energy Storage Bow - Stern Disconnect

7 Lumped Loads by Zones Lumped Loads (at 800 VDC Level) Battle Mode (kW) Cruise Mode (kW) Zone 1 DC Loads DC Loads Type 1 AC Loads /208 VAC Loads Non-vital, Type 1 AC Loads Non-vital,120/208 AC Loads -7 Total Power

8 Accomplishments Five zonal notional one-line diagrams for baseline system configurations and models –MVAC several variants in various tools Full scale, all switched converters, in RTDS (with DCZEDS) Several reduced scale variants in various tools –MVDC Full scale, all switched converters, in RTDS Few reduced scale variants in Matlab, VTB –HFAC Reduced scale in Matlab Defined several types of lumped loads by zone for both battle and cruise modes Developed equipment relational database –Static electrical and thermal loads for different operational modes (Shore, anchor, low power, cruise, battle & sus-battle) Common one line diagram of the thermal management system –Visualization of both electrical and thermal loads under different conditions Documentation at
