摘要
载波保护通道每天需要交换信号进行通道测试。早期依靠变电站值班员人工检测,变电站无人值守后,无法进行人工检测。现在大多用遥控检测,但遥控检测实施困难,且可靠性和安全性较差。本文结合地区电网载波保护通道自动检测系统的建设,提出了基于载波保护通道自动检测装置和载波保护通道异常智能识别的载波保护通道自动检测实现方法,证明了载波保护通道自动检测系统在电网运行监控方面良好的应用前景。
Carrier protection channel is required relies on manual detection in the past, and manual to carry out the channel test every day. The test detection cannot be carried out in unattended substations. Remote control may be an alnative, but it is very difficult to implement. In addtion, its reliability and safety is poor. Based on the construction of the carrier protection channel automatic detection system in a regional power network, this paper puts forward a carrier protection channel automatic detection method, which is based on the carrier protection channel automatic detection device and the carrier protection channel abnormality intelligent identification function. It is proved that the carrier protection channel automatic detection system can be widely used in power monitoring and control.
