随着光纤通信技术的飞速发展,光纤已作为一种重要的主干通信载体在电信、电力通信领域广泛应用。近年来,由于电力系统配电网自动化及变电站无人值班等电力系统运动技术的需要,通信问题已显得越来越重要,光纤通信在电力系统实时通信领域的应用有着独特的优势。例如在配电系统自动化系统中,用光纤实现调度对线路RTU[简称FTU]的1对N通信,可以有较高的传输速率和极高的抗干扰性,误码率将大大降低,同时降低开发和实际工程的费用。但是,由于光纤通信“T”接和中继要求有较高的技术处理和费用,给工程带来了不少麻烦,本文通过对FTU通信板做一个小的技术处理而解决了这一问题;同时,本方案也对利用电缆的1对N串行通信增加传输距离有一定的应用意义。
With the rapid development of optical fiber communication technology, optical fiber has been widely used in telecom and power communication fields as an important trunk communication carrier. In recent years, communication problems have become more and more important due to the needs of power system automation such as power system distribution network automation and substation unattended operation. The application of optical fiber communication in the field of real-time power system communication has unique advantages. For example, in the power distribution system automation system, the optical fiber can be used to schedule one-to-N communication of a line RTU [FTU for short], which can have a higher transmission rate and a very high noise immunity. The bit error rate will be greatly reduced while reducing Development and actual project costs. However, due to the higher technical processing and cost required for optical fiber communication “T” access and relaying, this project has caused a lot of troubles. This paper solves this problem by making a small technical processing on the FTU communication board; At the same time, this scheme also has certain application significance to increase the transmission distance with 1-to-N serial communication using cables.
