On September 14, Fujian Electric Power Co., Ltd. organized the first comprehensive monitoring system for real-time 110 kV opto-electric composite cable real-time operating system organized by Fujian Electric Power Co., Ltd. – Pingtan’s 110kV optical composite cable real-time running integrated monitoring system passed the review in Fuzhou. Formally put into operation, thus realizing the 7×24-hour three-dimensional monitoring of Pingtan submarine cable.
At the review meeting, the review panel carefully listened to the work reports, technical reports, test reports, user reports, and scientific review reports of the project team members, and watched the video data of the project development. After thorough questioning, conscientious discussion, and comprehensive review, review experts agreed that "the project has advanced application technology, outstanding comprehensive performance, and strong practicality. The research results have reached the international advanced level and have a good promotion and application value."
It is reported that the 110 kV photoelectric composite submarine cable in Pingtan, Fujian Province, is China's first domestically produced 110 kV photoelectric composite submarine cable. It crosses the Haitan Strait between Pingtan Island and the mainland, and is a busy maritime shipping channel. The waters in the area are in deep water and the sea conditions are complex. With the increasing use of marine development and utilization activities, the effects of aquaculture, fishing, transportation, and shore-based operations within the sea area on submarine cables cannot be ignored. In order to master the health status of submarine cable operation in real time and ensure the safe and stable operation of the transoceanic power grid, the responsible unit Fujian Electric Power Co., Ltd. and Fuzhou Electric Power Co., Ltd. jointly established a joint task force for the North China Electric Power University and began preparations for the development of the seabed in July 2010. The real-time running integrated monitoring system for cable development work. After half a year's investigation, the main framework and technical plan of the system were preliminarily determined. In 2011, the trial and selection of major equipment, the design of software system function modules and the development of programs were conducted in nearly a year, and the major technical difficulties in the system were further studied. In April 2012, after completing a series of work such as system hardware and software installation, commissioning, and on-site training for operators, the system formally entered the trial operation stage.
The research and development of the integrated monitoring system for real-time operation of the 110 kV photoelectric composite cable in Pingtan, Fujian Province mainly uses the redundant spare optical fiber of Pingtan's 110 kV photoelectric composite submarine cable to study the construction of distributed strain based on Brillouin optical time-domain reflection technology. Temperature measurement (BOTDR) 110kV optical composite cable operational status monitoring system, established a three-dimensional information database of latitude and longitude of the submarine cable, and merged AIS information and video monitoring system linkage to achieve the sea Hidden trouble monitoring. In addition, through the development of the GPMS-OMDS interface with the Fujian Power Transmission and Distribution Equipment Online Monitoring and Diagnosis Center System, multi-system networking, data fusion and bidirectional data transmission and unified maintenance management of the information platform with the monitoring center are realized. Since the trial operation, the effect has been remarkable.
At present, the project has applied for a number of patents to the State Intellectual Property Office. After the results are solidified, it will further submarine cables such as transoceanic power grids, offshore wind farms, offshore oil platforms, and defense and other submarine cables between the mainland power grid and other islands and islands. It lays a foundation for the promotion and application of communication cable monitoring.
