摘要
介绍了电气化铁路单相牵引供电负序的基本概念,详细分析了负序对发电机、电动机、电力变压器、输电线路和继电保护的负面影响,论述了对电气化铁路中单相牵引供电负荷负序影响采取对策的必要性,提出了改变这种不良影响的对策。
The basic concept of the single phase tractive power negative sequence to the electrified railroad was introduced in this paper. It analyses the negative influence of negative sequence influence to generator, electric motor, power transformer and transmission line. It is necessary to take counter measure to the negative sequence influence of single phase power load. The counter measures to change the negative influence were also proposed.
