海底电缆综合监测关键技术及应用
Application and Key Technologies of Submarine Cable Integrated Monitoring
摘要
Abstract
Submarine cable is an important passage of cross-sea power delivery. Due to the lack of effective monitoring technology, the power failure and fault of submarine cable usually occur. In this paper, the submarine cable compound optical fiber is used as the sensing element to build a submarine cable integrated monitoring system. The system can moditor the operation state of submarine cabel in real-time. The technical principles of Brillouin scattering on the strain and temperature and the principles of Rayleigh scattering on vibration sensitivity are introduced. The operation temperature, strain state and vibration of submarine cable can be monitored. The results can support the stable operation of the cross-sea power grid. The research results have been getting markable effect in practice and have wide prospect in application.关键词
