摘　　要：随着城市电网的改造,许多变电站改变为无人值守站并装置了遥视系统,但往往只能在监控中心网段内才能看到遥视信号。组播传送技术的出现可以有效地解决这一问题,因为该项技术能在传输满足需要的视频数据流和保证网络性能上找到平衡点。基于此,简单介绍了IP组播体系,并结合实际,探讨了在城域网内为管理和抢修人员提供变电站无人值守遥视画面的方法和步骤。Along with the reconstruction of the city electrical network, many substations have been changed into unmanned station and equipped remote video monitoring system, hut usually the remote video information only can he seen in the control center. IP multicast technology can resolve this problem effectively, because a balance point between delivering a great deal of video data and ensuring network performance can he found by using this technique. Accordingly this paper briefly introduces the IP multicast and discusses how to provide remote video information in MAN for the managers and maintainers.
