Emerging cybersecurity vulnerabilities in supervisory control and data acquisition (SCADA) systems are becoming urgent engineering issues for modern substations. This paper proposes a novel intrusion detection system (IDS) tailored for cybersecurity of IEC 61850 based substations. The proposed IDS integrates physical knowledge, protocol specifications, and logical behaviors to provide a comprehensive...
With the development of IEC 61850 smart substations, emerging cybersecurity vulnerabilities in supervisory control and data acquisition (SCADA) systems are becoming an urgent engineering issue for modern substations. This paper proposes a novel intrusion detection system (IDS) tailored for cybersecurity of IEC 61850 substations. The proposed IDS analyzes multidimensional physical knowledge and behaviors...
The conventional optical cable labels in smart substations contain too little information to support operation or maintenance. To solve this problem, this paper introduced a QR (Quick Response) code system for labeling and identification of optical cable labels in China's smart substations. The label format is specified for three kinds of cables, and the implementation methods of generation module...
In order to analyze the switching transient electromagnetic fields generated by the aerial busbars in substation, the one-dimensional (1-D) time domain finite element (TDFE) method is presented to analyze the transient wave process in multi-conductor transmission lines (MTLs) with branches. Based on the Pade's approximation and on Prony's method, the iterative equations of the aerial MTLs are reported...
