摘　　要：通过分析220kV双母四分段的一次主接线在不同运行方式下母线失压时可供选择的备用电源及实现备用电源的选择需具备的一些基础逻辑条件,提出按照母线的运行方式来设置充电方式,即单段母线按照所具备的备用电源来设置充电方式、并列运行母线组团备投及设置主备投和后备备投方式的设计思路。采用设置备投方式及可备投元件备投优先级的方法,解决了单母分列运行和多段母线并列运行时备投方式及备投元件的选择问题。The 220 kV duplicate-bus four-subsection wiring has complex operation modes. Based on the analysis of alternative back-up power and some basic logical conditions for selection in different operation modes with busbar voltage faliure.we propose to set the charging mode according to the operation modes of the bus, setting the charging mode of single bus on the basis of its own back-up power, while the charging mode of connected buses is considered as a whole and to set the main and back-up backup automatic switch modes. In addition, the selection of back-up modes and back-up elements is achieved by setting priority.
