基于自适应卡尔曼滤波器研究了智能电网假数据注入攻击检测问题.首先通过给出电网的状态空间模型,对两种攻击进行描述:随机攻击和假数据注入攻击.其次,研究表明常用的卡方检测器可以有效检测随机攻击,但无法检测出隐蔽假数据注入攻击.由此进一步在分析假数据注入攻击隐蔽性的基础上,考虑实际噪声变化的影响,提出基于R,Q自适应动态估计的卡尔曼滤波器的方法检测此类攻击,给出其设计过程,并对隐蔽假数据注入攻击提出了检测判断方法.最后进行Matlab仿真实验,验证了提出的隐蔽假数据注入攻击检测方法的有效性.

Chinese Journal of Aeronautics 1997年第3期10卷 42-47页

作者： zhu Zhishou, Cao Chunxiao, Ma Jimin, Gao Yang, Yan minggao (Beijing Institute of Aeronautical Materials, Beijing, 100095, China)

The influences of strain amplitude ranges and dwell time at peak strains on the low cycle fatigue (LCF) properties at 600℃ of a new near α high temperature titanium alloy containing rare earth Nd are investigated. The creep fatigue interaction behavior is discussed in this paper in terms of a creep fatigue interaction cumulative law and fatigue crack propagation model. The results show that the creep fatigue interaction is largely dependent on the strain amplitude range, and the tensile dwell periods, as well as compressive dwell periods, have a great influence on the LCF life of this alloy.
