Relay protection in wind power systems serves the purpose of detecting and isolating faults that may occur within the system. These faults include electrical faults such as overcurrent, overvoltage, or short circuits, as well as mechanical faults like imbalance or misalignment of. Switching devices that control and protect electrical systems in wind turbines, relays are essential components that monitor electrical parameters and trigger appropriate responses when abnormal conditions occur. These specialized switches serve as crucial safety mechanisms that isolate circuits. Index Terms—Directional protection, Distance protection, Line differential protection, Renewable generators.
