Abstract: Aiming at the shortcomings of traditional security protection for power monitoring systems in attack detection, traceability and unknown threat response, this study constructs a power monitoring decision-making system by integrating knowledge graph and large model technologies. Multi-source heterogeneous data is processed through standardized processes, entity recognition and relationship extraction are used to build a knowledge graph, and a special large model for network security is combined to achieve intelligent threat detection and analysis. The system has core functions such as threat detection and attack traceability, and can monitor in real time, locate accurately and provide operation and maintenance suggestions. Practices show that its attack detection accuracy, unknown attack recognition ability and traceability efficiency are better than traditional technologies, with an average vulnerability detection accuracy of 95.5%. It improves the system security and decision-making intelligence level, providing technical support for the digital transformation of the power industry.

引言
隨著電力行業數字化轉型加速,電力監控系統作為智能電網的核心,其安全性關乎電力系統穩定運行和國家能源安全。然而,工控系統結構復雜、設備定制化程度高,傳統安全防護手段在應對新型網絡威脅時存在諸多不足,如攻擊檢測準確率低、溯源能力弱、對未知威脅檢測能力弱等問題[1]。知識圖譜[2]和大模型技術[3]的發展為解決這些問題提供了新途徑。知識圖譜可整合多源數據,挖掘網絡威脅與系統要素的關聯;大模型憑借強大的語義理解和模式識別能力,能精準分析異常行為。將兩者結合應用于電力監控系統,構建決策系統,有助于提升系統的安全性和決策效率,保障電力行業的可靠運行。
