电力系统网络及设备的SDN演进研究

智能电网的建设发展催生了大量的电力新业务，电力系统网络和设备面临巨大的挑战，传统的网络和设备逐渐跟不上电力新业务的发展。在分析电力系统业务与网络设备发展现状以及SDN/NFV技术特点的基础上，将电力系统网络设备划分为两种模型：传统网络设备模型和SDN/NFV网络设备模型，提出了电力系统网络及设备在控制平面和数据平面的演进原则，总结了电力系统网络及设备的演进方向，给出了电力系统内应用SDN/NFV网络设备模型的应用案例设计和分析，为电力系统网络及设备的发展及建设提供参考。

Research on SDN Evolution of Networks and Devices in Electric Power System

Development and construction of smart grid has spawned a large number of new electric power services, and devices networks in power system are facing enormous challenges, and the traditional network and equipment is hard to keep up with the gradual development of the power of new services. On the basis of development presence of services and network equipment in power system, and SDN/NFV technical characteristics, divide the power system network equipment into two models: the traditional network equipment model and SDN/NFV network equipment model, propose the evolution principles of control plane and data plane for the network and equipment in power system, and summarize the evolution direction of networks and devices in power system. An application case design and analysis using SDN/NFV network equipment model is also given to be reference for the network and device development and construction in power system.
