| Abstract | |
Wind farms are becoming increasingly significant as renewable energy resources continue to expand, largely due to advancements in Inverter-Based Resources (IBRs). As widely reported in the literature, IBRs directly impact the operation of conventional protection. However, much of this research focuses on protecting transmission lines interconnecting IBRs to the primary grid. Assessments of the challenges and solutions for protection systems operating within wind farm collector networks remain limited in the literature. In this context, this research examines the performance of conventional protection functions within a real-world onshore wind farm by conducting realistic simulations on PSCAD/EMTDC software. In addition to addressing the challenges in the operation of overcurrent and directional overcurrent functions through parametric analyses, this paper contributes to the state-of-the-art by presenting tests on commercial relays. It also outlines recommendations for protecting wind farm collector systems. Aspects such as the most promising protection functions and the best positioning of relays to enhance protection schemes are highlighted. (AU) | |
