| Abstract: | Electrification railway's characteristics about traction transformer's connecting formation,engine's electric feature,and reactive power compensation are firstly introduced. Secondly the features and effects on power system of harmonics and negative-sequence current are analyzed,including load wave generated by electrification railway,which would be harmful to capacitor,relay protection and electric power metering. The measures to reduce these effects are provided. In the end, a series of ways to deal with electrification railway's harm are suggested to the electricity sector. |
