The scope of this project encompasses the design and analysis of the Cal Poly Power System at the distribution level using the SKM software environment. The purpose is to accurately model the power system in software so theoretical calculations and analysis can be executed. This requires sufficient preliminary research to obtain data for the main buildings on campus, sound interpretation of one line diagrams, designing the system within the software using realistic values and then performing analysis to model real world situations. The data collected is under maximum load conditions for a specified time period using medium voltage parameters. The analysis performed includes load flow, fault analysis (short circuit) and an arc flash study. Using this data facilities personnel can implement future protective devices in vulnerable areas of the power system, recognize and alleviate large load conditions using generators or alternative energy solutions, wear proper personal protective equipment (PPE), and analyze the impact of adding or removing machines or cables from the system. After the completion of this project I learned about typical power system design and protection schemes used to isolate faults. Troubleshooting a large power system is another important skill I developed from this endeavor. Additionally, this project has provided me with real world knowledge regarding power system devices like transformers, and allowed me to learn a new powerful software tool used in industry today.
