摘　　要：特高压交直流电网的不断建设发展,对电力系统通信提出了更高的要求。因此,发展超长站距光通信技术对于减少光中继站数量、降低工程建设规模及投资、减少维护量具有重要的意义。文章分析了超长站距光通信系统的限制因素和关键技术,探讨了超长站距系统的功率及OSNR计算,最后简要介绍了超长站距光通信技术在电力系统中的几个应用案例。Along with the construction of Ultra High Voltage （UHV） AC/DC transmission networks by SGCC, power telecommunications network faces more challenges. It is very important and urgent to develop ultra-long span optical transmission technology to reduce repeater stations, project scale and investment. This paper first discusses restriction factors and key technologies of ultra-long span optical transmission system, and then it analyzes the calculation of power and OSNR. Finally, it introduces some application examples of ultra-long span communication technology in electric power system.
