Research of the Structure and Working Mechanisms of Wide-Area Backup Protection Agent

Abstract

The multiple agents in wide-area backup protection system cooperate in parallel to detect and cut the fault quickly with narrow scope, using wide-area information. Based on wide-area backup protection algorithm, the structure and working mechanisms of wide-area protection agents are proposed. The agent's multi-layer structure with multi-component is constructed; as well as the working flow is analyzed. The cooperating associated scope which includes cooperative members is set up. Based on messages of data or request type, the equal coordination model is brought forward for wide-area protection agent. The cooperating strategies and joint rules which aim at the fault-tolerance are adopted to overcome the exiting and partial failure of one agent and refusal operation of relay, improving protection performance of whole system.
