A primary and backup cooperative protection system based on wide area agents

摘要: This paper presents a study of wide area agents based on communication for primary and backup coordinated protection. Agents are used to give each protection component control capacity as well the ability communicate with other agents. We feel that this method naturally points toward new philosophy Simulations illustrate concepts, using simulation engine called EPOCHS combines EMTDC/PSCAD power simulator NS2 network communications simulator. Results show improved performance our scheme. In system, were embedded in conventional components construct an IED relay. The agent searches relevant information by communicating Agent can take place at same substation or remote substations. be detect faults, relay misoperation, breaker failures, compensate such problems much better than done traditional schemes. Preliminary results us hope proposed scheme may able contribute mitigation wide-area disturbances blackouts frequently follow them.
