Abstract: With the large-scale integration of distributed renewable energy and diversified development of user-side loads, smartdistribution networks face significantly increased demands for "real-time" and "reliable" fault handling. Traditional faultlocation and self-healing control models relying on centralized cloud computing suffer from high data transmission latency,excessive bandwidth consumption, and insufficient reliability under extreme conditions. This paper proposes an intelligent faulthandling solution for distribution networks that integrates IoT and Edge Computing. The solution employs multi-terminaldevices deployed at the IoT perception layer to achieve multi-source fault data collection. Edge nodes perform localized datapreprocessing, fault localization algorithms, and self-healing control strategies to reduce cloud interaction latency. A three-tierarchitecture of "perception-edge computing-collaborative control" is constructed to clarify functional roles and data interactionmechanisms across layers. Using the IEEE 33-node distribution network model, a simulation platform is established to compareperformance differences between traditional cloud-based approaches and the proposed solution.
