December 2, State Grid Putian Power Company successfully conducted a 220 kV Zhuang change to turn the first end of the optical equipment switch automatic light path test. During the test period, the performance monitoring of the trunk optical fiber cable in the communication network was normal and the data was clear, marking the successful commissioning of the first optical domain intelligent management system of Fujian Electric Power. The system put into operation, will greatly enhance the operational reliability and security Putian communications network, and better power grid security, stability and reliable operation to provide strong support.
It is reported that the intelligent light domain management system is a combination of hardware and software that integrates the currently mature electronic, communications, computer, GIS and optical fiber measurement technologies. It is also a technological revolution of fiber optic cable monitoring system and also a traditional ODF Line frame) intelligent distribution of fiber optic system upgrade. It mainly solves the operation and maintenance problems of the optical cable with the characteristics of large capacity and long relay distance. When the intelligent optical domain management system detects that the receiving optical power of the optical cable is too low, an alarm is triggered and an OTDR (optical time domain reflectometer) is started to test the optical cable so as to accurately locate the fault - and to pass the traditional passive detection mode To the intelligent monitoring mode of active monitoring, real-time alarm, optical path automatic switching and optical bypass protection, which greatly improves the reliability of the optical cable, solves the problem of single equipment failure on a single link of the communication network and does not affect the communication of other stations, It also provides a strong basis for timely maintenance of communication status. Through the reliable and effective operation of the system, it solves the problems of long-term maintenance and testing of optical fiber cables and the accuracy of optical cable fault diagnosis, saves a lot of human resources, improves the accuracy of test and maintenance indicators, and ensures the reliability and stability of optical cable systems. Serious shortage of personnel structure, shorten the communication cable fault repair time 60%, to achieve the standardization of communication cables, standardization, lean management, to ensure that power communication network communication cable reliable and stable operation, to ensure the reliable operation of the communication network.
In order to better use and maintain this intelligent management system of light domain, communication personnel of Putian Power Supply Company have talked face to face with system designers on many occasions. From the system framework to the design principles, it has made in-depth and detailed Discussed, discovered and solved the problem of optical path automatic switching and optical bypass protection. After affirming the reasonable application of system design, the correspondents also estimated the possible operation of the system after commissioning, operation, overhaul and fault, and put forward relevant revisions on the actual operation requirements. At the same time, the company also organized the special training activities of the optical domain intelligent management system and conducted key training and discussions on the principles of logic, operational characteristics and precautions so that everyone could have a clear idea of ​​what to do when the system was put into operation response.
