【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。基于OTN通信系统的光路可靠性研究主要以构建光路模型为主,考虑了通信电源与设备内部各个逻辑结构的可靠性,全面细致地计算了不同节点与链路的可靠度,通过比较不同可靠性的研究方法,在分解法、最小割集法、最小路集法和状态列举法中选择最小路集法作为计算电力通信系统整体可靠性的方法。业务可靠性是影响系统整体可靠性的一个重要方面,论文采用模糊层次分析法研究基于OTN通信系统的业务可靠性,提出了模糊一致矩阵,为各组成因素对电力通信网的安全可靠性影响作定量分析。
[Abstract]:Power communication network is an important part of power network, which is an indispensable unit to ensure the normal operation of power network. With the development of communication technology, the second generation optical network based on OTN has become the main developing direction of communication transmission network. Reliability and security are the important evaluation to ensure the stable and healthy operation of power communication network system. The failure rate of communication network with high level of reliability is low and the repair time is less. This paper introduces the concept and technology of OTN from the development of communication transmission network, analyzes the advantages of OTN equipment, the networking mode and application mode in power communication network, and calculates the reliability of OTN network system composed of OTN equipment. Based on the analysis of the optical circuit composition and service of power communication network, the reliability is mainly analyzed by the measure of validity. Different research methods are put forward from two aspects of the reliability of communication optical circuit and the reliability of traffic respectively. The research of optical path reliability based on OTN communication system mainly focuses on building optical path model, considering the reliability of each logical structure inside communication power supply and equipment, and calculating the reliability of different nodes and links in detail. By comparing different reliability research methods, we select the most path set method as the method to calculate the overall reliability of power communication system in the decomposition method, the minimum cut set method, the minimal path set method and the state enumeration method. Service reliability is an important aspect that affects the overall reliability of the system. In this paper, fuzzy analytic hierarchy process (FAHP) is used to study the service reliability of OTN communication system, and a fuzzy consistent matrix is proposed. Quantitative analysis is made for the influence of each component factor on the safety and reliability of electric power communication network.
