1. Senior Design: Team SD1101 Client: City of Breda/Breda Municipal Electric system Advisor: James D. Mcalley Team Members: David Mindham(EE), RuiBai(EE), Anthony Tong(EE), Christopher Krantz(EE TEAM NAME: “BREDA TRANSFORMERS”

2. Overview Project Plan • Problem Statement • Conceptual Sketch • Functional Requirements • Non-functional Requirements • Technical/Other Constraints/Considerations • Market survey – articulate what makes your project unique • Potential Risks & Mitigation • Resource/Cost Estimate • Project Milestones & Schedule

3. Problem Statement • Create a functional one-line diagram using ETAP software • Collect, research, and report economic analysis of companies providing power to city of Breda • Advise and educate city of Breda on alternate sources of energy and money saving techniques

4. Concept Diagram

5. Market Survey • Phase 1 development of small town model power distribution system • Understand costs associated with small towns in Iowa

6. Economic Analysis Design • Collect cost data for the following areas: Generation, Transmission, Distribution, and Regulation. • Many costs are hidden. • Once cost breakdown is complete, we’ll know which areas we can have the greatest impact.

7. Cost Analysis • Generation Charges: MEAN and WAPA • Demand Charges: MEAN and Midwest ISO • Transmission Charges: MidAmerican and Midwest ISO

8. Functional Requirements • One-line diagram of the power distribution system of Breda • Power analysis • Harmonic distortion analysis • Loss analysis • Model Requirements • 7.2/12.74 kV • 3 MW peak input power • Primary line: 1 aluminum conductor steel reinforced(ASCR) • Secondary line: 4 ASCR • Transformers type: Liquid immersed • Motors: 120-250 HP • Line impedances

9. Non-Functional Requirements • Safety • Electrical • Travel • Team work • Reliability • Alternative energy • IEEE Standards • Power Factor Maintenance: +/- 5% of unity. • Cost Effective Upgrades: All suggested improves must pay for themselves in 15 years. • Non Technical Document: All reports must be easily understood by a non engineer (City Clerk.)

10. Constraints/Considerations • Team learning how to use ETAP • ETAP data is only as good as the model developed • Data for model continually requiring updates • Length of conductors • Types of fuses

11. Technology • ETAP Power Distribution Analysis Software • Provided by Iowa State University

12. Risks and Mitigation

13. Resource Cost Estimate ETAP provided by Iowa State University: No Cost
