Abstract :
This paper presents a multi-agent and WAN based adaptive coordinated protection system (MAWBACPS). The system utilizes IP intranet to realize real-time wide area information exchange of a power system. Multi-agent system´s several good qualities to solve distributing problems are used to realize the coordination of the operation settings of protective relays. A new idea of effortful adaptation for power system protection is proposed, and a new method to determine adaptive coordinated relay settings of lines are proposed in this paper. Moreover, the structure, communication mechanism and coordination control strategy of MAWBACPS, and relating agents´ design are presented. Experiment results illustrate that MAWBACPS can realize the coordination of protections, enable the back-up relays to use their adaptive settings in most situations, and efficiently improve the security of power system
