摘　　要：随着电缆入地工程的稳步推进,电力电缆工程的监测日益重要,但是监测系统的供电及通信方面缺乏统一的解决方案,难以保障监测系统稳定的长时间运行.而能信共传监测技术则为地下电缆监测提供了解决方案,文中提出了在光纤能信共传技术应用下电力电缆工程监测设备的一套标准化配置,优化电力电缆工程应用低功耗场景下多类传感器电压、功耗与光电耦合等效电路模型的电力传感器携能标准接口之间的匹配度.试验表明,通过文中提出的能信共传技术,在相同能量传输工况下,传输效率提高约12%~20%.此外,信号传输稳定性也有一定的提高.With the steady progress of underground cable installation projects, the monitoring of power cable projects has become increasingly important. However, there lacks a unified solution for the power supply and communication aspects of the monitoring system, making it difficult to ensure the stable long-term operation of the monitoring system. The optical fiber coherent transmission monitoring technology provides a solution for underground cable monitoring. This paper proposes a standardized configuration for monitoring equipment in power cable projects using optical fiber coherent transmission technology. It optimizes the matching between power sensors of various types, such as voltage, power consumption, and optoelectronic coupling equivalent circuit models, under low-power consumption scenarios in power cable projects. Experimental results show that with the proposed optical fiber coherent transmission technology, under the same energy transmission conditions, the transmission efficiency is increased by about 12% to 20%. In addition, there is also an improvement in signal transmission stability.
