Research on Practical Technology of Intelligent Fault Diagnosis

and Self-healing Control in Distribution Network

Huang Da-qu

[Abstract]The intelligent construction of distribution network makes it have strong fault intelligent diagnosis ability， and supports the system self-healing to a certain extent. Its main working principle is to identify and judge faults through intelligent diagnosis technology， send early warning signals in time， and start the self-healing control system in the early warning state for intelligent treatment of distribution network faults， so as to ensure the stable and reliable operation of distribution network system. It is a key technical project of current power construction. This paper mainly discusses the practical technology of distribution network fault intelligent diagnosis and self-healing control， defines its concept and complete control technology system， and hopes to provide corresponding technical guidance for distribution network fault identification and treatment.
