摘　　要：目前电力调度主要依赖于调度自动化主站,主站中广泛使用局域网(Local Area Network,LAN)冗余技术。经过一系列的研究表明,在网卡主备模式下备用网卡状态难以得到实时监视,这是由于网卡的负载均衡导致不能侦测到非直连链路的异样。为了能够合理规划局域网的建设、运维,提出了冗余可靠性推荐方案,以此来指导局域网设计。At present,power dispatching mainly relies on the dispatching automation master station,and the Local Area Network(LAN)redundancy technology is widely used in the master station.After a series of studies,it is shown that it is difficult to monitor the status of the standby network card in real-time in the active-standby mode of the network card.This is because the load balancing of the network card cannot detect the abnormality of the non-direct link.In order to reasonably plan the construction,operation and maintenance of the local area network,a recommended scheme of redundancy reliability is proposed to guide the design of the local area network.
