【摘要】：隨著經(jīng)濟社會的發(fā)展以及智能電網(wǎng)建設(shè)的加速,電網(wǎng)的負荷量以及信息化水平不斷增長,在結(jié)構(gòu)、運行方式等方面呈現(xiàn)出越來越復(fù)雜化的特點,逐步形成一個復(fù)雜大電網(wǎng)。作為電力系統(tǒng)的信息通信專用網(wǎng)絡(luò),電力通信網(wǎng)承載著電力生產(chǎn)與管理的全部業(yè)務(wù),其安全穩(wěn)定對于保障電網(wǎng)正常運行具有關(guān)鍵作用。針對電力通信網(wǎng)開展安全風(fēng)險分析工作對于保證電力通信網(wǎng)安全穩(wěn)定運行,對于保障電力安全生產(chǎn)具有重要意義。本文基于電力通信網(wǎng)的組網(wǎng)特點,針對電力通信網(wǎng)中不同結(jié)構(gòu)的網(wǎng)絡(luò)進行針對性的風(fēng)險分析,對電力通信網(wǎng)風(fēng)險評價模型進行重點研究。對于電力通信網(wǎng)中安全需求非常高,采用SDH技術(shù)組網(wǎng)的調(diào)度數(shù)據(jù)網(wǎng),側(cè)重分析網(wǎng)絡(luò)與電網(wǎng)之間的聯(lián)系,利用所提拓撲單元的概念,將網(wǎng)絡(luò)劃分為多個拓撲單元。通過分析網(wǎng)絡(luò)連接結(jié)構(gòu)得到拓撲單元可靠性,并將拓撲單元所承載的業(yè)務(wù)與包含的節(jié)點重要性相結(jié)合得到拓撲單元故障嚴重度,最后將拓撲單元可靠性與故障嚴重度融合得到拓撲單元風(fēng)險評價指標。根據(jù)網(wǎng)絡(luò)各拓撲單元的風(fēng)險值,計算得到評價網(wǎng)絡(luò)整體風(fēng)險的指標。而對于帶寬需求高,采用OTN技術(shù)組網(wǎng)的綜合數(shù)據(jù)網(wǎng)則從拓撲角度分析網(wǎng)絡(luò)在面對不同攻擊方式下維持網(wǎng)絡(luò)連通的能力,通過分析網(wǎng)絡(luò)脆弱性評估網(wǎng)絡(luò)風(fēng)險。利用基于因子分解法建立的K端可靠性計算模型,求解子域邊界節(jié)點之間的二端可靠性,作為邊界節(jié)點之間虛擬鏈路的可靠性值,并代替邊界節(jié)點之間的拓撲結(jié)構(gòu),以簡化網(wǎng)絡(luò)結(jié)構(gòu),再結(jié)合K端可靠性模型計算網(wǎng)絡(luò)可靠性值。最后利用隨機攻擊與蓄意攻擊兩種模型分析網(wǎng)絡(luò)風(fēng)險。結(jié)合不同網(wǎng)絡(luò)結(jié)構(gòu)特點提出針對性的風(fēng)險分析方法,評價結(jié)果更具合理性與實用性,在電力通信網(wǎng)具備一定應(yīng)用前景。
[Abstract]:With the development of economy and society and the acceleration of the construction of smart grid, the load of power grid and the level of information are increasing, and the structure and operation mode are becoming more and more complicated. As a special information and communication network of power system, electric power communication network carries all the business of power production and management. The safety and stability of the network is very important to ensure the normal operation of the power network, and to carry out security risk analysis to ensure the safe and stable operation of the power communication network, Based on the characteristics of electric power communication network, this paper analyzes the risk of different structures in electric power communication network. This paper focuses on the risk assessment model of electric power communication network. For the high security requirement in power communication network, the dispatching data network based on SDH technology is used to analyze the connection between the network and the network, and the concept of the proposed topology unit is used. The network is divided into several topological units, the reliability of the topology unit is obtained by analyzing the network connection structure, and the fault severity of the topology unit is obtained by combining the service carried by the topology unit with the importance of the node included. Finally, the risk evaluation index of topology unit is obtained by combining the reliability of topology unit with the degree of fault severity. According to the risk value of each topological unit of the network, the index of evaluating the overall risk of network is calculated. The integrated data network based on OTN technology is used to analyze the network's ability to maintain network connectivity in the face of different attack modes from the point of view of topology. By analyzing the network vulnerability assessment network risk and using the K terminal reliability calculation model based on factor decomposition method, the reliability of two terminals between subdomain boundary nodes is solved, which is regarded as the reliability value of virtual link between boundary nodes. And replace the topological structure between the boundary nodes to simplify the network structure, Finally, the network risk is analyzed by using random attack and deliberate attack models. Combined with the characteristics of different network structures, a targeted risk analysis method is proposed. The evaluation results are more reasonable and practical, and have a certain application prospect in electric power communication network.
