摘要
随着通信技术的发展,光纤通信已逐渐成为继电保护通道中的主要传输方式,所以要高度重视光纤保护通道的可靠性。可靠性框图是对复杂系统的可靠性进行建模和分析的一种强有力的工具,文章介绍可靠性框图的基本原理,并对实际的光纤保护通道进行建模和分析。最后用Relex公司生产的Relex Studio软件仿真计算,得到保护通道的可靠性指标,为分析光纤保护通道的可靠性提供了依据。
With the development of communication technology, optical fiber communication becomes the main transmission means for relay protection signals. Reliability Block Diagram （RBD） is a tool used for modeling and analyzing the reliability in a complex system. This paper describes the basic principle of RBD, models and analyzes the actual fiber relay protection channel, and calculates the reliability parameters of fiber relay protection channel with the Relex Studio simulation software produced by Relex Company.
