Abstract
A multi-Agent based wide-area current differential protection system is proposed. By means of expert system the dynamic online partitioning of primary and backup protection zones of current differential protection system is implemented, then through the coordination among the Agents of different protections the primary and backup differential current protection for whole power network is realized. The knowledge representation of expert system to partition the primary and backup protection zones of the differential protection and the protection zones searching strategy are worked out, the behavior rule and communication mode for the coordination among the Agents of different protections are presented. The simulation of communication system of this protection system is conducted and the predictive self-healing measures to prevent the maloperation of differential protection are put forward when the communication of protection Agent is interrupted or other failures occur.
