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:

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
