摘要：
The growing penetration of the distributed generation (DG) makes the traditional passive distribution network change to active distribution network.. A new fault location method is proposed in this paper based on the change of the current phase, which can be used in active distribution network. Specifically, a fault model of the invert DG is proposed, then the active distribution network model is established. The current phase difference between the two ends of the distribution line are calculated for both the normal operation and fault conditions. The relationship between the current phase and the location of the fault is summarized. A fault location criterion is proposed based on the change of the current phase difference. The correctness and effectiveness of the proposed method is verified using the practically measured data and the fault simulation.
