【摘要】：随着智能变电站二次装置标准化、智能化水平的提升,需要有一种更高效、智能的通信网络以满足变电站运行和维护要求,能够实现设备即插即用、智能监测、子网间安全隔离以及设备通用互换。针对智能站网络统一管理、子网间安全隔离以及设备兼容性、互换性的应用需求,提出了一种基于软件定义网络(SDN)技术的变电站网络架构,将IEC61850和OpenFlow协议用于网络架构设计,利用OpenFlow控制器管控和隔离各独立子网,以实现网络设备管理和子网安全隔离。实验结果表明,所提架构可实现流量基于业务类型的精准控制和数据的安全隔离,对于提升变电站运行和维护水平有着非常重要的应用价值。
[Abstract]:With the standardization of secondary devices in intelligent substation and the improvement of intelligent level, it is necessary to have a more efficient and intelligent communication network to meet the requirements of substation operation and maintenance. Security isolation between subnets and general exchange of equipment. Aiming at the application requirements of intelligent station network unified management, security isolation between subnets, equipment compatibility and interchangeability, a substation network architecture based on software definition network (SDN) technology is proposed. IEC61850 and OpenFlow protocols are used in the design of network architecture. The OpenFlow controller is used to control and isolate the independent subnets to realize the network equipment management and subnet security isolation. The experimental results show that the proposed architecture can realize accurate traffic control based on service type and data security isolation. It has very important application value for improving substation operation and maintenance level.
