Differential Protection of Main Transformer of Doubly-Fed Wind Farm Based on Current Synthesized Vector Trajectory Characteristics
“In the field of wind farm fault crossing, experts have proposed a new time-domain protection scheme based on current synthesis vector trajectory characteristics, which effectively identifies faults within the area, with a fastest action time of 15 milliseconds and an average action time of less than one power frequency cycle.”
