Abstract In this paper, the in-depth analysis of power distribution protection with distributed energy is combined with the possible causes of bidirectional power distribution network faults. A method for discriminating fault direction components based on the positive-sequence current phase change is proposed. It is verified through experiments that the fault can be accurately identified Section, which has certain practical promotion value, and provides a protection method for the safe and stable operation of power systems containing distributed renewable energy.
