为提高智能配网可靠性,实现电网故障的准确定位和快速隔离,需要对继电保护业务进行实时可靠传输。借鉴输电环节,采用光差保护是一种合理方案。文章通过对光差保护业务和EPON技术进行深入分析,研究了传统EPON网络承载光差保护业务在时延、抖动和同步等方面存在的问题,针对性提出解决方案,为智能配网光差保护承载网络建设提供参考。
In order to improve the reliability of intelligent distribution network and realize the accurate positioning and quick isolation of grid faults, real-time and reliable transmission of relay protection services is required. Learn from the transmission link, the use of light protection is a reasonable program. This paper analyzes the optical protection business and EPON technology in-depth analysis of the traditional EPON network bearer light protection business in terms of delay, jitter and synchronization aspects of the problem, put forward solutions to targeted for intelligent network protection with light protection Bearer network construction provide a reference.
