光纤通信论文：四纤自愈环技术在电力通信网中的应用研究 【中文摘要】电力通信网主要承载继电保护、调度数据、营销自动化、电能量采集、生产MIS等重要信息。随着电力系统的快速发展和电网数字化、信息化建设步伐的加快,电力系统通信需要传输的信息量也在快速增长,对电力通信网的要求也越来越高。由于唐山电力通信网在建设初期多为链状网络结构,网络的安全性、可靠性和灵活性较差,缺乏电路的自动恢复功能,对电力生产、经营等造成一定影响。本文在对SDH自愈环保护技术的基本原理和国内外研究与应用现状进行分析的基础上,结合唐山地区现有电力通信网络的状况,分析了四纤自愈环技术相对于其它自愈环方式的优势和不足及采用四纤自愈环技术进行改造的必要性和可行性。结合唐山地区电力通信业务的进一步需求和现有网络资源状况,设计了基于四纤自愈环的唐山地区电力通信网组网方案和继电保护通道路由方式,并重点对自愈环传输时延参数进行了理论分析和计算。完成了基于四纤自愈环的唐山电力通信网方案的实施与误码、抖动、时延等系统性能指标的测试和分析工作。测试结果表明,设计的网络完全能够满足电力系统调度数据、营销自动化、电能量采集、生产MIS等重要业务的需求,也能满足继电保护通道对延时收发一致的要求。基于四纤自愈环的电力通信网具有生存性高,网络恢复时间短,业务容量大,业务疏导能力强等优点,能够满足电力系统业务的需求,具有应用和推广价值。 【英文摘要】The electric power communication networks mainly transmit the relay protection, dispatching data, marketing automation, electric energy acquisition, MIS and other information. With the rapid development of power systems and the digitalization and informatization of grid, the amount of information need to be transmitted and the requirements of power communication networks are growing fast. In the early stage of Tangshan power communication networks抍onstruction, the networks mostly are chain configuration, so the security, reliability, flexibility and the auto-recovery circuit are infficient, which affect the power production and management.The paper is based on the fundamental principles and of the domestic and foreign research and application situation of SDH self-healing ring protection. It not only analyzed the advantages and disadvantages of four-fiber self-healing rings compared with other methods, but also researched the necessity and feasibility of the transformation of four fiber self-healing ring technology combined with the existing status of Tangshan electric power communication networks. Considered with the further demand for power communication services and the existing network resources, the electric power communication network programs and protection channel routing which based on the four-fiber ring are designed, and focused on the theoretical analysis and cal
