Wind Power Plant Impacts on Distance Protections-Real Time Relays Testing

The increasing integration of inverter-based resources (IBRs) into power transmission systems leads to significant challenges to power system protection schemes, particularly for distance relays (DRs). DRs were developed based on the behaviour of synchronous generators (SGs) during faults on the grid and are still used to protect grids interconnected with IBRs. However, the endogenous current limitation and dynamic voltage support provided by IBRs during faults can cause DRs to mis-operate. RTE, the French TSO, is currently investigating the impact of
