摘　　要：随着先进通信与信息技术的广泛应用,虚假数据注入攻击已成为威胁自动发电控制系统安全的重要因素之一。网络攻击的检测是防御的首要任务,文中提出了一种基于集员滤波的自动发电控制系统虚假数据注入攻击检测方法。首先,针对自动发电控制系统中虚假数据注入攻击的影响进行了分析,并建立了互联电网自动发电控制系统模型以及虚假数据注入攻击的模型。其次,基于实时自动发电控制系统的控制指令以及测量数据,对自动发电控制系统椭球集进行预测更新和测量更新,通过判断预测更新椭球集与测量更新椭球集之间是否存在交集,检测系统的数据传输中可能存在的虚假数据注入攻击。最后,在IEEE标准双区域互联电网中验证了所提方法的有效性。With the wide application of advanced communication and information technology,the false data injection(FDI)attack has become one of the important factors which threat the security of automatic generation control(AGC)system.The detection of cyber-attacks is a priority for defense.This paper proposes a method of FDI attack detection for AGC system based on the setmembership filtering.Firstly,this paper analyzes the influence of the FDI attacks in AGC systems,and establishes a model of AGC system of interconnected power grids and a model of FDI attacks.Secondly,based on the real-time control commands and measurement data,the prediction update and measurement update of the AGC system ellipsoid set are performed.By determining whether there is an intersection between the prediction update ellipsoid set and the measurement update ellipsoid set,the possible FDI attacks in the data transmission of the system are detected.Finally,the effectiveness of the proposed method is verified in the IEEE dual-area interconnected grid.
