摘要
我国电力系统自动化技术与智能电网的建设与发展对长距离时频传递精度与可靠性提出更高需求。地基光纤授时由于其传输媒介具有抗干扰能力强和抗毁性高等优点,结合级联传递技术,可为长距离、高稳定、高可靠的频率传递提供坚实保障。文章详细总结分析了近些年国内外光纤频率级联传递系统架构和发展现状,并对未来长距离光纤频率传递技术的发展趋势及其在电力系统中的应用前景进行展望,为天地互备的时频同步网建设提供支撑。
The establishment and growth of China's power system automation technology and smart grid necessitate enhanced precision and dependability in long-distance time-frequency transmission.Ground-based optical fiber timing has the advantages of strong anti-interference ability and high invulnerability due to its transmission medium.Combined with cascaded transmission technology,it can provide a solid guarantee for long-distance,high-stability and high-reliability frequency transmission.This paper detailly summarizes and analyzes the architecture and development status of optical fiber frequency cascaded transmission system at home and abroad in recent years,and looks forward to the future development trend of long-distance optical fiber frequency transmission technology and its application prospect in the power system,which will provide support for the construction of time-frequency synchronization network with satellite-earth mutual backup.
