Project Description TASK: Design a new 115kV substation (switchyard) to service ISU –Voltage Level Transformations –Inter-system communication with other substations (OUTSIDE SCOPE) –Regional transmission line connection –System health monitoring capabilities –System protection

Scope of Services/Deliverables Physical Campus Layout Foundation Layout One-line Diagram Three-line Diagram Bus and Insulator Sizing Grounding grid design Component Raceway Design Transformer Design 125VDC System Battery Design Relay Design Control System Design Control House Layout Control House Service NOT INCLUDED: System Simulation and Transformer Design

Project 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

CONSTRAINTS Burns & McDonnell expectations Standards –Industry Specific –Component Specific –Environmental Specific Hierarchy of development dependency RISKS Hierarchy of development dependency Learning curve Design validation Project Constraints & Risks
