【摘要】：随着保定供电公司农电资产“上划”和“三集五大”管理模式的推进,伴随着业务流量的不断增加,以光缆和TDM为基础的传统传送网络传送效率较低的劣势就突显出来,保定电力系统现有的传送网基于光纤及现代交换等通信技术,组成了传输网、业务网及支撑网,传送网刚性管道承载的分组业务,限制了汇聚比,导致业务统计复用效率低。导致其难以适应全业务对带宽需求,并造成了巨大的传送成本压力。电力PTN网络承载了管理信息业务,电量采集、视频会议、信息内网、信息外网、行政电话、电视会议等业务种类也随之不断丰富。本文围绕PTN在电力专网的应用进行研究。首先,按照“统一规划模式、技术路线和政策、技术体制”的原则,结合地区、县通信网现状,对县光传输系统进行技术研究。然后,结合保定供电公司的现有通信网的从网络结构、设备层次等方面进行研究。最后,对PTN网络的承载能力,业务模型、业务隔离、传输特性、传输时延、传输带宽、组网应用等方面进行了研究,对PTN业务路径保护等技术体制、承载的业务类型、电网业务的适用性以及与现有数据网网络、传输网络对接等方面进行分析和研究。本课题所研究的保定供电公司调度、行政语音业务、无人值守变电站视频监控、电量采集、视频会议等业务应用,以及对电力PTN网络改造与中长期的通信规划、技术发展协调一致,对电网光传输网平稳、健康过渡和发展具有很好的工程意义。
[Abstract]:With the development of the management mode of "top drawing" and "three sets and five" in Baoding power supply company's agricultural power assets, along with the continuous increase of service flow, the disadvantage of low transmission efficiency of traditional transmission network based on optical cable and TDM has been highlighted. The existing transmission network of Baoding power system is based on optical fiber and modern communication technology. It consists of transmission network, service network and support network. The packet service carried by rigid pipeline of transmission network limits the convergence ratio. As a result of low efficiency of service statistics reuse, it is difficult to adapt to the bandwidth requirement of the whole service, and cause huge pressure of transmission cost. Power PTN network carries management information service, electric power collection, video conference, information intranet, information extranet, etc. This paper focuses on the application of PTN in electric power network. Firstly, according to the principle of "unified planning mode, technical route and policy, technical system," The present situation of the county communication network, the technical research on the county optical transmission system. Then, combining the existing communication network of Baoding Power supply Company from the aspects of network structure, equipment level, etc. Finally, the bearing capacity and service model of the PTN network are studied. Service isolation, transmission characteristics, transmission delay, transmission bandwidth, networking application and so on are studied. The technical system of PTN service path protection, the type of service bearing, the applicability of power network service and the network with existing data network are studied. Transmission network docking and other aspects of analysis and research. This research Baoding power supply company scheduling, administrative voice services, unattended substation video monitoring, electricity acquisition, video conferencing and other business applications, It is of great engineering significance for the transformation of power PTN network and the medium and long term communication planning, and the coordinated development of technology, for the smooth, healthy transition and development of the optical transmission network of the power network.
