摘　　要：随着智能电网和能源互联网的不断深入发展和推进,云计算、数据仓库、数据挖掘以及虚拟化等技术在电力行业的成熟应用,现有电网已无法满足业务的需求。软件定义网络(software defined network,SDN)作为新兴网络架构实现了控制功能和数据转发功能的解耦,是未来电力通信网络架构的选择之一。文中通过对SDN网络原理的论述,详细讨论了基于SDN的电力通信网络需要解决的关键技术,主要包括网架性能、安全性、时延、可扩展性、链路可靠性、容错性和兼容性,最后展望了软件定义网络相关技术在电力系统中的应用领域。With the continuous development of the smart grid ,the energy internet,the application of cloud computing,bigdata,data mining and virtualization technology in the power industry,the electric power telecommunication has been unable tosatisfy the requirements of the power system. As a new network architecture,software defined network （SDN）realizesdecoupling of the control function and data transmission function,which is one of the choices of future electric powertelecommunication network architecture. Based on the principle of SDN network that is discussed in the paper,the keytechnology of electric power telecommunication network based on SDN is shown in detail. And the key technologies are asfollows：performance,security,scalability,delay,link reliability,fault tolerance and compatibility. What’s more,this paperdiscusses the application of prospect of SDN in Power System with great prospect.
