AbstractThis paper analyzes the impacts of Inverter-Interfaced Wind Power Plants (IIWPP), namely Full-Converter Generators and Doubly-Fed Induction Generators, on directional and phase-selection protection functions employed in commercial relays. For the studies, a system with a typical topology used to connect IIWPP to the grid was modeled in MATLAB- Simulink software, and contingency scenarios varying the fault type, resistance, and location were simulated. The obtained results reveal several IIWPP operational particularities which impact the directional and phase-selection protection functions.
