AI Technical Summary
After large-scale access to distributed power supply, electric vehicles and controllable loads, traditional distribution network fault diagnosis methods cannot effectively solve the increase in fault false alarm rate and the accuracy of fault diagnosis.
By comprehensively utilizing the node overcurrent information monitored by the feeder terminal system (FTU) and the high-precision electrical quantity information collected by the micro synchronous phasor measurement unit (μPMU), four active distribution network fault diagnosis electrical quantity criteria were constructed, and a fault diagnosis analysis model was constructed to solve the optimal fault hypothesis.
Accurate diagnosis of active distribution network faults is achieved, the accuracy and reliability of fault diagnosis is improved, the fault false alarm rate is reduced, and additional equipment is required.
