摘　　要：目前电力通信网所采用的是以主机为核心的传统网络组建方式,该模式在运营中表现出的设备投资大、管理成本高、升级难度大等问题,使其越来越难以满足电力系统信息化发展与创新的需要。在分析电力通信网承载业务特点的基础上,结合当前互联网发展趋势提出了一种基于软件定义网络(SDN)的新型电力通信网络架构,该架构具备的高性能、高可靠性、易扩展等特性,同时还可以便捷、低成本地实现网络管理、扩展升级以及新业务研发与部署。Communication networks play a key role in power system development. Nowadays, power communication network adopts traditional ＂host-centric＂ networking architecture. This leads to high cost in investment, maintenance and operations which cannot meet increasing development and innovation needs of power system. Based on analysis of power communication network service, a novel power communication networks architecture based on software-defined network （SDN） concepts is proposed. Proposed framework can achieve high levels of networking performance, reliability and scalability. It is suitable for continuous evolution of innovating and management of networking at low-cost. It also has good scalability during development and deployment of new business applications.
