基于视频确认的变电站顺控操作系统

Sequence Control System in Substation Based on Video Confirmation

目前变电站的顺控操作都需要人为干预,工作效率低,自动化程度不高。由于电网对变电站顺控操作的准确性要求高,目前顺控操作防止误操作机制单一,因此无法满足电网对安全性的高要求。本文在原有防误逻辑的基础上提出一种通过模板特征匹配视频分析算法来视频识别设备当前运行状态的方法,对顺控操作中刀闸、翻字牌等设备状态进行高精度可靠识别,实现了顺控操作不同源信号双确认,增加了防止误操作的途径,大大降低了顺控操作中系统误判率,也减少了顺控操作人工参与,提高了变电站顺控操作的工作效率和自动化程度,为电网安全运行提供了保障。

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.
