光纤通信是电力输电线路保护及控制信号最重要的传输手段。由于遥泵放大技术在国内电力系统中尚无正式运行案例, 设计经验较少, 因此, 如何设计可靠的超长距离遥泵放大光纤线路, 成为电力系统通信亟待完善的课题。文章介绍了遥泵放大技术的基本原理, 提出了一种适合在电力系统超长距离光纤通信工程中采用的遥泵放大系统方案, 并结合实际工程案例进行分析。所提出的设计方法可作为电力系统超长距离遥泵放大系统设计的重要参考。

Fiber-optic communication is the most important transmission means for power line protection and signal control. By now there is not yet any case of the commercial operation of Remote Optical Pump Amplifier (ROPA) system in China's electric power grids and so no design experience, therefore it is a research subject to be urgently enhanced to design a reliable ultra-long-distance ROPA fiber-optic circuit for electric power system communication. This thesis introduces the basic principle of the ROPA technology, presents a ROPA system scheme adoptable in practical project and analyzes this scheme in connection with practical project cases. The proposed design method can be used as important reference for the discussed system design.
