Abstract

This paper conducts a case study-based review related to the impacts of Inverter-Based Wind Power Plants (IBWPP), namely Full-Converter Generators (FCG) and Doubly-Fed Induction Generators (DFIG), on self-polarized quadrilateral and memory-polarized mho distance protection functions. Besides evaluating two of the main polarization strategies for distance protection, different grid code requirements, concerning the reactive power regulations by IBWPP upon grid disturbances, and the impact of the DFIG crowbar circuit were analyzed. To do so, several contingency scenarios varying the type, resistance, and fault location were simulated, in a system with a typical IBWPP interconnection topology with the primary grid. By assessing the impedance trajectories in the complex plane and the phase comparators, usually considered by commercial relays, it was possible to prove and explain in detail the misoperations of the distance protection functions for systems with IBWPP.
