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
Concept Diagram
Market Survey
Phase 1 development of small town model power distribution system
Understand costs associated with small towns in Iowa
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.
Cost Analysis
Generation Charges: MEAN and WAPA
Demand Charges: MEAN and Midwest ISO
Transmission Charges: MidAmerican and Midwest ISO
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
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.)
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
