Abstract: Currently, the substation sequence control system is manually operated with low efficiency and low degree of automation. Because State Grid Corporation has put forward high requirements on the correct use of the substation sequence control system, the single anti-misoperation mechanism in the sequence control system cannot meet the high security requirements that are set by State Grid Corporation. Based on the original fail-safe logic, this paper provides a method to identify the current operating status of the device through the video, using the template feature to match video analysis algorithms, and to recognize operating status of the device such as the disconnecting link and on-and-off device with high accuracy and reliability. As a result, different signal sources of the sequence control system are double-checked. The ways to avoid misoperation are increased. The false positive rate of the sequence control system is greatly decreased. The number of workers who operate the sequence control system is decreased. The work efficiency and automation degree of the substation sequence control system are enhanced. The safe operation of State Grid Corporation is guaranteed.
