随着数字化技术、5G技术、工业自动化等科技的不断进步,电力系统向着更加智能、更加高效的趋势发展,催生了智能变电站的产生。变电站二次回路系统负责对一次系统的运行进行控制、监测、保护、调节,是变电站的控制核心。智能化变电站是基于对二次回路系统通过网络实现相关数据的收集、分析与智能化控制,提出的一种基于虚拟回路技术智能变电站二次回路故障检测方法,从流程展开研究,依托网络消息分析器作为判断辅助,并结合现有技术,提出一种在线监测诊断光纤链路方案且给出相关算法。

With the continuous progress of digital technology, 5G technology, industrial automation, etc., power system is developing towards a more intelligent and efficient trend, which has spurred the emergence of intelligent substations. The secondary loop system of substation is responsible for controlling, monitoring, protecting and adjusting the operation of primarysystem, which is the control core of substation. Intelligent substation is based on the collection, analysis and intelligent control of relevant data of secondary loop system through network. We propose a fault detection method for secondary loop of intelligent substation based on virtual loop technology. Our research mainly starting from the process, relies on the networkmessage analyzer as a judgment aid, and combines the existing technologies, puts forward a scheme of online monitoring anddiagnosis of optical fiber links, and gives relevant algorithms.
