摘　　要：对光纤比例联差动保护的应用进行了分析,在对不同保护和通道的连接方式进行比较后,提出了采用2M复用连接方式应该是比较好的选择;讨论了保护通道测试参数、通道异常时的处理方法及在实际应用中出现的问题及解决的方法;讨论了采用光纤纵差保护后旁路带路的方法,指出四方公司新推出的CSC-186M装置是较好的方法和发展方向。The article analyses the application of the fiber longitudinal differential protection. After investigating different connecting models of the protection and channel, the article puto forward the suggestion that the 2M multiplex connecting model would be appropriate, discusses treatments for abnormal testing parameters of the channel and abnormal situation of the channel itself as well as some problems emerged in application and the solution. The article also studies the methods of bypass leading after adopting the fiber longitudinal differential protection and points out that the CSC- 186M device developed by Sifang Automation Company would be more practical for the problems and be used more widely in the future.
