220 kV双母线带旁路接线变电站代路操作比较

Comparison of Substitution Operation for 220 kV Double Bus Substation with Bypass Connection

通过梳理双母线带旁路接线方式下旁路2246开关转代线路运行操作的注意事项,对比所代线路配置纵联距离或纵联方向保护(高频保护)和纵联电流差动保护(光纤保护)的代路操作,强化不同保护配置线路代路操作方法,便于变电运维人员掌握2种代路的差异。

In this paper,comb the operation precautions of transmission through the bypass 2246 switching under the double-bus with bypass connection mode,and compare the operations of transmission through by-pass between lines with longitudinal distance or longitudinal direction protection(high frequency protection)and longitudinal current differential protection(optical fiber protection).Strengthening the operation methods of different protected configuration lines through comparatation,and facilitating the power special staff to master the differences between the two routing methods.
