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...
This paper proposes the idea of evaluation system, with trend and loss evaluation model of secondary device set up, which is useful for equipment condition monitoring and assessment in smart substation. Multi-parameter identification method is firstly introduced, by “horizontal comparison and longitudinal check”, the correction of device state can be guaranteed. Standard of score for different parameters...
With interoperation and interconnectivity of intelligent electronic devices (IEDs) in smart substations increasing, switch networks in smart substations are gradually becoming difficult to manage and maintain. This paper presents a dynamic topology discovery method tailored for smart substation networks based on MAC address matching, which goes beyond topology discovery algorithms for conventional...
