Capstone Project
Impact of Inverter-Based Resources on Transmission Line Distance Protection
- Performed transmission line distance protection analysis using SEL protective relays and RTDS hardware-in-the-loop simulations.
- Modeled inverter-based resource penetration scenarios and assessed impacts on apparent impedance measurements and relay reach characteristics.
- Executed single-line-to-ground, line-to-line, and three-phase fault studies to evaluate protective relay response.
- Configured relay settings, event reports, and oscillography analysis to verify protection coordination and fault clearing performance.
- Utilized real-time power system simulation tools to replicate utility-scale grid operating conditions.
- Analyzed protection challenges associated with renewable generation integration and inverter-based fault current behavior.
