摘　　要：文中提出并实现了一种基于点对点通信、按功能组织的分层分布双总线通信方案。通过引入镜像节点、总线负荷均衡等技术,使该方案可灵活高效地实现分布自动化功能和信息局部整合,并消除了分层通信对系统通信可靠性和速度的影响,同时,定量分析了该通信方案的可靠性。此通信方案已在部分变电站得到实际应用,并取得了理想效果。A layered and distributed dual-bus communication scheme is presented and designed, which is point-to-point based and organized according to functions. The mirror and bus load balancing techniques are introduced into the scheme to make it flexibly and efficiently realize the distributed automation function and the local information integration function, eliminating the effects of the layered scheme on the communication speed and reliability. The reliability of the proposed scheme is quantitatively analyzed. The scheme is being successfully applied in some substation automation systems.
