摘　　要：随着信息设施的不断改善,大量的分布式发电机(DGs)将会接入配电网。为此,运用多代理技术提出了一个新的配电网保护方案。该方案中,各种不同的继电器被设计成继电器代理,区域内的继电器相互合作以定位和隔离故障。通过感知在继电器处的电流突然变化,来选择二元状态信号(电流的方向,幅值大小等)作为保护用信号。每个继电器同时利用同一区域的其他继电器所提供的二元状态信号用于探测故障位置。通过PSCAD/EMTDC仿真测试,结果表明该保护方案能够满足具有大量DGs的配电网的保护要求,能够有选择性和快速性地断开故障区域。With the improvement of information facility′s,massive distributed generators（DGs）will connect with the distribution network.A new distribution network protection plan based on the multi-agent technology is proposed in the paper.In the plan,all the relays are designed as the relay agents,which will cooperate each other to locate and isolate the fault.Through sensing electric current′s sudden change at relay,chooses the dual status signal（electric current direction,magnitude and so on）used in the protection plan proposed.Each relay simultaneously utilizes the dual status signal provided by other relays involved in the same zone for detecting a location fault.The PSCAD/EMTDC simulations show that the proposed protection plan can satisfy the massive DGs distribution network′s protection request,and may contribute to a selective and quick disconnection of faulted zone.
