摘　　要：通过分析比较光纤分相电流差动保护和光纤纵联距离零序保护在原理性能、对保护通道要求方面的异同之处,认为在通道条件允许前提下,220 kV线路双重化保护宜优先选用双套光纤分相电流差动保护的配置。The comparisons between optical fiber phase-splitting current differential protection and optical fiber pilot zero sequence protection in terms of their principles and requirements on protection channel lead to the conclusion that under the premise of channel conditions,the choice of two sets optical fiber phase-splitting current differential protection should be given priority to for the duplicate protection of 220kV line.
