摘要
针对变电站继电保护二次回路存在的安全隐患问题,设计一种基于光纤通信的隐患排查系统.该系统利用光纤传感技术对电流、电压等参数进行高精度测量,通过光纤以太网实现高速数据传输,并在应用层引入机器学习算法进行故障诊断.最后,搭建实验平台,对 500 kV变电站进行为期 1 个月的监测,结果显示设计系统的平均诊断准确率达97.5%,诊断时延低至75 ms,网络时延抖动小于10 ms,为提升变电站继电保护可靠性提供了新的思路和方法.
Abstract
Aiming at the hidden dangers in the secondary circuit of substation relay protection,a hidden danger investigation system based on optical fiber communication is designed.The system uses optical fiber sensing technology to measure parameters such as current and voltage with high precision,realizes high-speed data transmission through optical fiber Ethernet,and introduces machine learning algorithm in application layer for fault diagnosis.Finally,an experimental platform was built to monitor the 500 kV substation for 1 month.The results show that the diagnostic accuracy of the designed system is 97.5%,the diagnostic delay is as low as 75 ms,and the network delay jitter is less than 10 ms,which provides new ideas and methods for improving the reliability of substation relay protection.
