摘　　要：针对深井煤矿综采、综放工作面的远程供电难题,提出了一种基于双包层光纤的远程供电系统,仿真分析了双包层光纤(DCF)供电链路远程天线单元输出传输能力和大功率供电能力。光纤供电通过中心控制站的馈电功率来管理远端供电单元的供电大小,井下数据通过单模纤芯进行传输,大功率供电通过双包层内部的包层进行传输。仿真结果表明,100 m的双包层光纤在远端供电单元可提供约800 MW的功率。在12 W大功率馈电的条件下,双包层的功率损耗可忽略不计,在实现大功率电远距离输送的同时可进行2.5 Gbps速率的双工通信。Aiming at the remote power supply problem of fully mechanized mining and caving face in deep coal mine,a remote power supply system based on double-clad fiber(DCF)is proposed.The output transmission capacity and high power supply capacity of the remote antenna unit of the DCF power supply link are simulated and analyzed.The optical fiber power supply manages the power supply size of the remote power supply unit through the feed power of the central control station,and the underground data is transmitted through the single-mode fiber core,and the high power supply is transmitted through the cladding inside the double cladding.The simulation results show that the 100 m of DCF can provide about 800 MW power in the remote power supply unit.Under the condition of 12 W high power feed,the power loss of the double-cladding can be neglected,and the duplex communication of 2.5 Gbps rate can be carried out while achieving the long-distance transmission of high-power electricity.
