摘要
分析了当前在500 kV线路保护中广泛应用的光纤差动保护,并以REL561保护和RCS931D保护为例,介绍了其在原理、功能等方面的特点,经过长期实践对光纤差动保护存在的一些不足作了归类分析并对保护的运行维护提出了解决方案。
This paper analyzes the optical-fiber differential protection which has been used widely for the 500 kV Transmission lines. REL561 and RCS931D protections are taken as examples to introduce its principle and functions. The disadvantages of optical-fiber differential protection are classified and analyzed, and the solution is put forward for the operation and maintenance.
