摘　　要：发电厂的母线是电厂中的一个重要组成元件 ,当母线上发生故障时 ,将使连接在故障母线上的所有元件在修复故障母线期间 ,或转换到另一组母线上运行以前遭到停电。同时还可能破坏系统稳定 ,造成严重后果。因此 ,母线保护装置是正确迅速切除母线故障的重要装置 ,它的拒动或误动将给电力系统带来严重危害。详细介绍了华能丹东发电厂 350MW发电机组采用的BUS 10 0 0型母线保护的原理 ,并对其正常运行及区内、外故障、断路器失灵保护、母联断路器过流保护等几个方面作了详细分析。Bus bar is an important component in electric power plant.When bus bar fault occurs,all components connected on the faulty bus bar will be in outage until power restores by repairing the faulty bus bar or switching them over to another bus bar.Furthermore,it may cause the destruction of system stability resulting in serious consequence.Bus bar protection device is the very device to quickly remove bus bar faults,and its malfunctioning will bring serious harm to power system. The principle of BUS 1000 bus bar protection used for 350 MW unit of dandong power plant is introduced.Its normal operation and several aspects,such as in and out area faults,out of order breaker protection,bus bar breaker over current protection,are analyzed in detail.
