【摘要】：隨著智能變電站二次裝置標準化、智能化水平的提升,需要有一種更高效、智能的通信網(wǎng)絡(luò)以滿足變電站運行和維護要求,能夠?qū)崿F(xiàn)設(shè)備即插即用、智能監(jiān)測、子網(wǎng)間安全隔離以及設(shè)備通用互換。針對智能站網(wǎng)絡(luò)統(tǒng)一管理、子網(wǎng)間安全隔離以及設(shè)備兼容性、互換性的應(yīng)用需求,提出了一種基于軟件定義網(wǎng)絡(luò)(SDN)技術(shù)的變電站網(wǎng)絡(luò)架構(gòu),將IEC61850和OpenFlow協(xié)議用于網(wǎng)絡(luò)架構(gòu)設(shè)計,利用OpenFlow控制器管控和隔離各獨立子網(wǎng),以實現(xiàn)網(wǎng)絡(luò)設(shè)備管理和子網(wǎng)安全隔離。實驗結(jié)果表明,所提架構(gòu)可實現(xiàn)流量基于業(yè)務(wù)類型的精準控制和數(shù)據(jù)的安全隔離,對于提升變電站運行和維護水平有著非常重要的應(yīng)用價值。
[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.
