This project establishes practical laboratory coursework facilitating student operation, coordination, and integration of microprocessor-based protective relays in low-voltage three-phase radial and bidirectional systems modeling utility power distribution. Seven laboratory experiments will be developed, creating a laboratory component to an existing power systems protection course. The laboratory coursework development is part of the Cal Poly electrical engineering department’s Advanced Power Systems Initiatives, which aim to modernize power engineering curriculum to more effectively educate power students and prepare them for the rapidly changing power industry. The radial system portion of the laboratory coursework includes a connection to the electric utility, feeding loads through a power transformer and lab-scale transmission line. The bidirectional portion of the lab expands the radial system with a generator and additional transmission line. Using the two setups, students will have the opportunity to learn various power system protection schemes, as well as familiarize themselves with the communication and coordination of recently donated industry-standard power system protection equipment. Learning outcomes are formulated based on the desirable skills students should attain from the subsystems and components making up the radial and bidirectional systems. This includes functional testing of various digital relays using a breaker box simulator, characterizing transmission line parameters, and setting up proper transformer connections. Further detailed descriptions of the seven experiments, along with their learning outcomes and assessment methods, will be presented in this paper. Initial results of testing the experiments will also be described, along with challenges and lessons learned in the development of the laboratory coursework.
