【摘要】：針對智能變電站保護(hù)控制信息安全風(fēng)險的防范問題,提出了智能變電站保護(hù)控制信息安全風(fēng)險防護(hù)的三道防線模型,包括以防入侵風(fēng)險為核心的第一道防線、以防傳播風(fēng)險為核心的第二道防線和以防失效風(fēng)險為核心的第三道防線。進(jìn)一步,針對第二道防線防傳播風(fēng)險技術(shù)的薄弱環(huán)節(jié),提出了基于報文識別與流量管控的保護(hù)控制信息傳播風(fēng)險防護(hù)方法以及相應(yīng)的安全交換模型,并基于OPNET搭建了智能變電站保護(hù)控制信息傳播風(fēng)險防護(hù)的仿真平臺。仿真結(jié)果表明所提出的保護(hù)控制信息傳播風(fēng)險防護(hù)方法在正常運(yùn)行情況下能夠優(yōu)化報文處理機(jī)制,在異常情況下能夠保障關(guān)鍵報文的可靠傳輸,從而有效提升了智能變電站通信網(wǎng)絡(luò)的抗風(fēng)險能力。
[Abstract]:Aiming at the problem of information security risk prevention of intelligent substation protection control information, this paper puts forward a three-line defense line model for intelligent substation protection control information security risk protection, including the first line of defense against intrusion risk. The second line of defense against spreading risk and the third line of defense against failure risk. Further, aiming at the weak link of the technology of preventing transmission risk in the second line of defense, Based on message identification and flow control, this paper presents a method of protecting and controlling the risk of information dissemination and the corresponding security exchange model. Based on OPNET, a simulation platform for risk protection of intelligent substation protection control information transmission is built. The simulation results show that the proposed protection control information dissemination risk protection method can optimize the message processing mechanism under normal operation. It can guarantee the reliable transmission of key packets under abnormal circumstances, thus effectively enhancing the risk resistance of intelligent substation communication network.
