摘要
研究了广域后备保护多Agent系统采用对等协商模式、UDP通信协议、SDH光纤环网的动态行为。对广域通信网络、通信协议及模式进行选择,在美国电力和通信同步仿真集成环境EPOCHS上构造通信网络的NS2模型,通过仿真实验统计网络通信延迟,分析两种电网故障下多Agent的交互协作过程、通讯模式和通信网络对广域后备保护动作时间的影响。实验表明,SDH通讯专用网能满足广域保护算法对通讯的需求。
The dynamic behaviors of wide-area backup protection multi-agent system, using equal negotiation mode, UDP （user datagram protocol） and SDH （synchronous digital hierarchy） optical-fiber ring networks, are studied, according to a kind of wide-area backup protection algorithm. The wide-area communication network is chosen, as well as the communication protocol and mode. The NS2 model of communication networks in the EPOCHS （electric power and communication synchronizing simulator） is constructed. The communication delays are obtained from the simulation test. The interactions among wide-area backup protection agents can be analyzed under two kinds of power system fault. The influence of communication mode and networks on action time of wide-area backup protection is studied. SDH networks can satisfy the requirement of protection algorithm. This work is a reference for future study of wide-area protection.
