With a large number of distributed power supplies connected to the distribution network,communication network failure has increasingly become a key factor affecting the safe and stable operation of the distribution network.This paper presents a fault detection and control method for distributed power group communication in distribution network.The method realizes intelligent data acquisition and processing through edge computing,uses wavelet transform and other technologies to extract multi-dimensional fault features,constructs Support Vector Machine(SVM)model for fault diagnosis,and realizes distributed coordinated control combined with agent.The experimental results show that the proposed method has excellent detection accuracy and control effect under various fault scenarios,and the system recovery time is controlled within 3 s.This study provides effective technical support for ensuring the safe and stable operation of the distribution network under high penetration of new energy.
