摘　　要：在地区供电网中,220kV线路单电源双回线供电是一种主要运行方式。为快速切除故障一般配置双套快速保护,现对这种运行方式下的相关保护运行问题进行探讨,并提出一些观点。In regional power supply network,single Power sources Double Circuit Feeding is a major operating mode of 220 kV lines. In these lines, double quick acting protecting systems are generally prepared for immediate fault removal. In this paper,some relevant problems of protecting equipments in this operating mode are discussed ,and some points of view are put forward.
