Abstract：Aiming at the problem relating to electricity transmission stopping and wind power abandonment caused by any short circuit in a power line of a wind farm, a single phase grounding fault location method based on all phase fast fourier transform (apFFT) spectrum correction and extreme gradient boosting (XGBoost) for the measured signals of the faulted line is proposed. During the research, the simulation models of doubly fed generators with multi branch hybrid power lines in a wind farm is firstly constructed, and the fundamental phasors of relating voltages and currents during a fault period are obtained by apFFT spectrum correction method to build an original feature set. Then the regression model on single terminal fault location is established by an algorithm called as XGBoost, and the model contains the feature importance and sorting of the fault and can be used to discover the relationship between the features and the fault distance. Finally the fault location can be estimated using the model based on the current input pattern. The experimental results by PSCAD/EMTDC show that the proposed method has distinct advantages in the fault location of a short overhead/cable hybrid line with multi-branches in a wind farm. Its fault location performance is better than random forest (RF) algorithm, and not affected by fault location and grounding resistance. It can meet the fault location accuracy requirement of a wind farm.
