海底电缆全天候安全监控技术应用

摘要

Due to the lack of efficient security monitoring technology,the submarine cable disruption occurs frequently caused by ship offending with hazards to the safety and stability of the cross-sea grid.For solving this problem,a safety monitoring technology for long-distance submarine cable with a good far-near complementation is proposed,which uses the integrated photo-electric radar and AIS system.First,the configuration and principle of the integrated photo-electric radar system is introduced.Then,the allweather omni-directional safety monitoring and controlling process using this system in practical cases of the long-distance submarine cable is reported.The result shows that the submarine cables can work more safely and stably with a good performance and prospect in application by the support of this technology.%海底电缆由于缺乏有效的安全监控技术,导致船舶锚害肇事等外力破坏事故时有发生,严重影响了跨海电网安全稳定运行.针对现有海底电缆海域监控技术的不足,采用了光电一体化雷达装置与AIS系统融合联动,进行远近配合优势互补的长距离海底电缆安全监控技术方案.介绍了光电一体化雷达系统组成和工作原理,并通过实际应用案例阐述光电一体化雷达系统对长距离海底电缆海域全天候、全方位安全监控流程.技术应用取得显著效果,支撑了海底电缆持续稳定安全运行,推广应用前景广阔.
