Differential Protection of Transmission Transformer for Large-Scale Doubly-Fed Wind Farms Based on Detrended Analysis

Since the fault current output from the doubly-fed wind farm has frequency deviation characteristics and contains large harmonic components, when an internal fault occurs in the transmission transformer for the doubly-fed wind farm, the ratio of the second harmonic to the fundamental wave in the dif...
