Through the series of proposed experiments, students program microprocessor-based relays using RS-232 protocol. Students identify and set the communication parameters for each relay and apply them when connecting serially between a desktop computer and protection device. Each procedure emphasizes the purpose and function of important relay settings. Electrical utility companies increasingly rely upon automated fault detection to improve the integration and effectiveness of emerging smart grids. Responding to these circumstances in the rapidly-changing power industry, the electrical engineering department at Cal Poly State University in San Luis Obispo created Advanced Power Systems Initiatives. The growing density of distributed energy resources (DERs) in utility circuits calls for new considerations in circuit planning and operation1. Bidirectional power flow, in which customers with DERs send power back to the utility, requires protection schemes accounting for changing directions of load current. The time-varying power output of certai. Assessment of student performance takes several forms. An instructor or assistant verifies circuit connections before students apply power and supervises them from a distance while they perform the procedure. Questions from the students during the procedure highlight points of confusion in the lab manual and suggest needed revisions. Each experimen. Throughout this set of proposed experiments, students program a variety of microprocessor-based relays and analyze fault data from relay-generated event files. Students coordinate relays in both radial and bidirectional circuit topologies, demonstrating primary and secondary protection functionality across each circuit. Proposed experiments resulti.
