Study On Distributed Intelligent Fault Disposing Mode In The Distribution Network

This paper deeply studies the distributed intelligent fault disposing mode in the distribution network.Its main contents are shown as follows:Many fault disposing modes in distribution automation are compared.Then the best fault disposing mode is put forward:the system protection mode based on the communication of neighboring protectors.The conception of system protection is introduced,the realizing scheme of main protection and back-up protection is deeply discussed.The sample has been finished.Aiming at the disposal of single-phase fault in distribution automation,the criterion of negative fault current is put forward. Combined with the theory of system protection,a new way is introduced for selection and orientation of single-phase fault.In the distribution network which has no communication,a scheme which uses the user line subsection switch to deal with the fault of the embranchment is put forward.
