| EduGrid Microgrid Demonstrator **Team Members:** - Jason Hart (jhart34) - Ahmet Colak (colak2) **Problem:** Students often have limited understanding of how the electric power grid is designed to stay safe and reliable, especially the protection systems, breakers, relays, fault isolation, that prevent small failures from becoming large outages. Because these concepts are not taught in a fun and accessible way, many students do not see what power engineers actually do or why the field matters, which can reduce interest in pursuing power and energy careers. Recent large scale outages, such as the winter storm related failures experienced in Texas, show how grid reliability, planning, and protection directly affect daily life and the safety of the public, highlighting the need for clear, hands on public education. **Solution:** Our product will include an interactable tabletop power grid that allows the user to see the flow of power from source to load, all while having access to switches and controls that aim to isolate faults, correct the power factor, and visualize the flow of power on our grid. All of these systems will provide students with an intuitive and engaging tool to learn more about the important role of power engineers. **Solution Components:** **Subsystem 1:** **Power distribution and DC/DC regulation:** Provides stable regulated power rails for the entire project so the ESP32-S3, display, LEDs, and indicators operate reliably. This subsystem converts the main input supply into a clean 5 V rail and a clean 3.3 V rail, with protection and power indication. - 5 V system rail Buck Switch Converters: TPS54202DDCR - 3.3 V logic rail Low Dropout Voltage Regulators: TLV75533PDBVR - Input power connector: 2.1 mm DC jack PJ-102A - Power switch: SPST toggle/slide switch (example: EG1218) - Protection: reverse Schottky diode SN74S1053DWR - Power indication LED: standard LED (WP7113SURDK14V) + resistor (generic) Subsystem 2: **Power grid state machine and fault initializer** The brain of the system that stores the states of feeders, faults, measurements, display text, and breakers. Displays voltage, current, and power factor for power factor correction. - Microcontroller: ESP32 S3 - Text-display showing V, I, PF, fault state: SSD1306 - Power factor correction (buttons to add capacitance or inductance): 108-D6C40F1LFS-ND **Subsystem 3:** **Feeder and breaker tripping behavior** The microcontroller will initialize fault scenarios that will require the user to manually trip breakers to isolate faults - Breaker toggleswitch: 100SP5T1B1M1QEH - Programmable LEDs for power-flow and fault visualization LED: WS2812B Subsystem 4: **Mechanisms for fault selection, activation, and protection success.** - Manual rotary selector: PEC11R-4220F-N0012 - Fault selection/activation light: 732-5017-ND - Buzzer for incorrect fault isolation: CUI CEM-1203 **Criterion For Success:** - Fault selection, activation, and isolation switches with clear LED/noise indication of success or failure. - Clear depiction of power flow and feeder/breaker location on the board's face. - Product is safely enclosed with now exposed conductors or excessive heating - Each fault state is selectable and operational. |
