中文摘要：

基于高速通信的多Agent保护系统，能够通过各个空间上分布的保护Agent之间的通信和配合来提高保护动作的可靠性、适应性和容错能力，但是保护Agent之间的通信延时对于基于多Agent的保护系统的性能有重要的影响．为了分析确定基于多Agent保护系统的应用条件，利用Network Simulator网络通信仿真软件，对不同通信协议、通信通道带宽和通信组织方式对继电保护系统通信延时的影响进行了仿真分析．仿真结果表明，在宽带以太网的基础上，利用多Agent通信能够满足继电保护系统的实时性要求．

英文摘要：

Multi-agent based protection system can achieve higher reliability, adaptation, and fault tolerance than average ones by communication and corporation of its related agents. Transmit delay plays an important role to the performance of multi-agent based protection system. In this paper, network simulator has been used to simulate and demonstrate impact of different communication protocols, communication bandwidth, and organization approaches upon communication delay of multi agent based protection system. The simulation shows that the substation based communication using muhicast UDP protocol can provide a least communication delay.
