南方电网调度数据网业务双平面承载关键技术

Key Technologies of the Dual Plane for Power Dispatching Data Network in China Southern Power Grid

为提高电网调度数据网业务的可靠性,南方电网采用了双平面承载的方法,通过路由策略、防止路由环路等关键技术,实现安全I区业务由A平面承载,安全II区业务由B平面承载;同时两平面互为冗余备份,当一个平面发生故障时,业务可自动切换至另一个平面承载。通过现网实际测试,验证了其可行性。

To improve the reliability of power grid dispatching data network in China Southern Power Grid, this paper introduces a dual plane for power dispatching data network. By some key technologies, such as route policies, no-loop route and etc., it comes true that security I and security II operations are taken by plane A and plane B respectively, and the two planes are redundant backup for each other, i.e. operations can switch from on plane to another automaticly in case of fault. The practical testing results validate the feasibility of the proposed method.
