摘　　要：结合内蒙古电网主网500 kV变电站的220 kV系统部分,探讨220 kV系统母线结构及常见死区故障,依靠母差保护、失灵保护将故障消除。重点分析因基建、生产等工程,设备投运前需进行充电。探讨2种充电方式的特点,提出对于新设备充电,选择基于保护装置充电至死区逻辑的充电方式,减少切除范围,避免隐患发生,保证电网稳定可靠运行。This article combines the 220 kV system of the 500 kV substation in the main grid of Inner Mongolia Grid to explore the busbar structure and common dead zone faults of the 220 kV system.It relies on bus differential protection and failure protection to eliminate the faults.The analysis focuses on the need to charge the equipment before operation due to infrastructure,production,and other projects.This article discusses the characteristics of two charging methods,and proposes that for the charging of new equipment,the charging method based on the protection device's logic of charging to the dead zone should be selected to reduce the scope of removal,avoid potential hazards,and ensure the stable and reliable operation of the power grid.
