發(fā)布時間：2018-12-09 15:55
【摘要】：電網中的二次安全防護系統(tǒng)是一個龐大的復雜系統(tǒng)，它的組成包括電力監(jiān)控系統(tǒng)、電力通信以及相應的數(shù)據網絡等。隨著時代的發(fā)展，網絡安全問題已經融入各行各業(yè)，電力二次系統(tǒng)的安全防護問題就顯得尤為重要，電力監(jiān)控系統(tǒng)以及電力調度數(shù)據網絡不受侵害是電網安全運行的前提，為了保證電力二次系統(tǒng)的安全運行，在以往的安全防護技術研究中已經形成了四項基本原則——“安全分區(qū)、網絡專用、橫向隔離、縱向認證”，并在此基礎上建立二次安全防護系統(tǒng)。 二次系統(tǒng)安全防護工作最重要的一點是通過有效的技術手段或者管理措施全力保護電力實時監(jiān)控系統(tǒng)以及調度數(shù)據網絡的安全運行，其終極目標就是建立起一個相對完善并且有成效的二次系統(tǒng)安全防護系統(tǒng)，即在所建立的安全策略下保護電力系統(tǒng)控制環(huán)節(jié)免受病毒、惡意代碼等的網絡侵害，尤其是要能夠抵御來自外部世界的有組織團體包括擁有豐富資源的威脅源所發(fā)起的惡意攻擊，，同時要求能減輕嚴重自然災害所造成的損失，使電力系統(tǒng)在遭到損害后能夠迅速恢復一定比例的功能，以防止二次系統(tǒng)安全事件引起進而導致電力一次系統(tǒng)事故甚至是大面積的停電事故，從而保證電力系統(tǒng)能安全穩(wěn)定地運行。 本文結合滇東電廠實施電力二次系統(tǒng)安全防護工作的經驗，在現(xiàn)有條件下對滇東電廠二次安全防護系統(tǒng)的體系結構以及相關技術進行了深入研究，并在此基礎上建立了滇東電廠二次安全防護方案。通過對滇東電廠的電力監(jiān)控系統(tǒng)和電力調度數(shù)據網絡的現(xiàn)狀分析，找出目前滇東電廠在電力信息安全方面存在的問題，并提出相應的安全改造方案包括：網絡結構調整、安全設備選型、安全技術措施、邊界清理和技術措施等。同時對本次安全改造中所用到的物理隔離、傳輸軟件等非通用技術裝置進行研究，分析其功能規(guī)范以及具體實現(xiàn)原理，并將其應用在滇東電廠電力二次系統(tǒng)安全建設中。 本文所研究的內容已經在滇東電廠二次系統(tǒng)安全防護系統(tǒng)工作中得到了實際的應用，效果已達到預期。
[Abstract]:The secondary security protection system in power network is a huge complex system. Its composition includes power monitoring system, electric power communication and corresponding data network. With the development of the times, network security has been integrated into various industries, the security protection of the secondary power system is particularly important, the power monitoring system and power dispatching data network is the premise of the safe operation of power grid. In order to ensure the safe operation of the secondary power system, four basic principles have been formed in the previous research on safety protection technology-"security zoning, network specialization, horizontal isolation, vertical certification". On this basis, the secondary safety protection system is established. The most important point of the security protection work of the secondary system is to protect the power real-time monitoring system and the safe operation of the dispatching data network through effective technical means or management measures. The ultimate goal is to set up a relatively perfect and effective secondary system security protection system, that is, to protect the power system control links from the virus, malicious code and other network violations under the established security policy. In particular, to be able to withstand malicious attacks by organized groups from the outside world, including resource-rich sources of threat, and to mitigate the damage caused by severe natural disasters, The power system can recover a certain proportion of function quickly after being damaged, so as to prevent the secondary system safety incident from causing the power system accident and even the large area power outage accident. Thus, the power system can operate safely and stably. Based on the experience of implementing the safety protection of power secondary system in East Yunnan Power Plant, this paper makes a deep research on the system structure and related technology of the secondary security protection system in East Yunnan Power Plant under the existing conditions. Based on this, the second safety protection scheme of East Yunnan Power Plant is established. Based on the analysis of the current situation of electric power monitoring system and power dispatching data network in East Yunnan Power Plant, this paper finds out the existing problems in electric power information security of East Yunnan Power Plant, and puts forward the corresponding safety reform scheme, which includes: network structure adjustment. Safety equipment selection, safety technical measures, border cleaning and technical measures. At the same time, the physical isolation, transmission software and other non-general technical devices used in this safety reform are studied, and its function specification and concrete realization principle are analyzed, and applied in the security construction of the secondary power system of the East Yunnan Power Plant. The content of this paper has been applied in the work of the secondary system safety protection system of the East Yunnan Power Plant, and the effect has reached the expectation.
