浅谈 OTN 的电力通信网可靠性摘要电力通信网是电力网的重要组成部分,是保证电力网正常运行必不可少的单元。随着通信科技的不断进步,基于 OTN 的第二代光网络成为通信传输网的主要发展方向。可靠性与安全性是保证电力通信网系统稳定、健康运行的重要评估,具有高级别可靠性的通信网故障出现率低,修复时间少。论文从通信传输网的发展历程介绍了 OTN 的概念和技术,分析了 OTN 设备的优点以及在电力通信网中的组网模式与应用方式,并计算了由 OTN 设备构成的 OTN 网络系统可靠性。通过分析电力通信网的光路组成与业务情况,主要以有效性为测度分析可靠性,具体并从通信光路可靠性和业务可靠性这两个方面,分别提出不同的研究方法。关键词:电力通信网;光路可靠性;业务可靠性;最小路集法On the reliability of OTN power communication networkMajor:Communication engineeringpower communication network is an important part of power network and an indispensable unit to ensure the normal operation of power network. With the continuous progress of communication technology, the second generation optical network based on OTN has become the main development direction of communication and transmission network. Reliability and safety is an important evaluation to ensure the stable and healthy operation of the power communication network system.This paper introduces the concept and technology of OTN from the development of communication transmission network, analyzes the advantages of OTN equipment and its networking mode and application mode in power communication network, and calculates the reliability of OTN network system composed of OTN equipment. By analyzing the optical path composition and service situation of power communication network, the reliability is mainly analyzed by taking the validity as the measure, and different research methods are put forward respectively from the two aspects of communication optical path reliability and service reliabil...
