[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.
