Setting the Stage

• Sponsor: Burns and McDonnell• Adviser: Dr. Ajjarapu

• Clarifications–Educational purposes only–Modified project plan


Project Description• What?

115kV substation (switchyard)• Where?

Hypothetical location on Iowa State campus• Why?

To accommodate a hypothetical new wind farm• When?

Immediately (utilizing tried and true current tech)• How?

Act as a contract team


Strategy Development• Project plan document• Design document• GANNT Chart• WBS (Work Breakdown Structure)• Legend of symbols• Bill of materials

These materials are provided on our website at: http://seniord.ece.iastate.edu/dec1303/index.html


Requirements• Design services

– Layout will allow for future expansion– 125 Volt Station Battery supply for station service

outage– Fiber-Optics communication between substations – The substation be designed with Iowa weather in

mind• Safety

– Clearance for emergency vehicles – Clearance for removal of defective parts– Ground grid capable of handling a fault

• Follow industry and company standards


Deliverables• One-line diagram• Three-line diagram• Physical campus

layout• Foundation layout• Grounding grid layout• Bus and insulator

sizing• Component raceway

• Service station transformer design

• Control house layout• Control systems• Relay wiring• 125VDC battery

design

ADVISER: Role within system description


Constraints & RisksProject Constraints• Burns and McDonnell

expectations• Standards• Hierarchy of

development dependency

Project Risks• Hierarchy of

development dependency

• Learning curve• Design validation

Solution: Design reviews


Project Resources

• Design Resources– Burns and McDonnell design team– Industry design standards– External Reference material


Team Breakdown• Jane Peters (Team Leader)

– project documents, one-line, control building, three-line, section cuts, relay wiring

• Jared Jasper (Team Webmaster)– website maintenance, site design, grounding layout, section

cuts• Riley Groves (Communications Coordinator)

– one-line, three-line, client communications, raceway, grounding layout, relay wiring

• Matt Murphy (Grounding Expert)– one-line, three-line, raceway, grounding, control building, bus

and insulator sizing• Muzi Li (Layout Expert)

– foundation design, grounding layout, site design, bus and insulator sizing


Project Verification

• Campus Resources–Dr. Ajjarapu–Dr. Christy–Weekly progress review meetings

• Burns and McDonnell Design Team–Bi-monthly design review meetings


Current StatusImplementation• One-line: COMPLETE

Reviewed by Burns and McDonnell

• Physical Campus Layout:IN PROGRESS– Seeking design

guidance– Referencing design

guides

Researched• Project Plan• Design Document• GANNT Chart• WBS• Symbology• Software packages

– AutoCAD– WinIGS
