| Abstract |
The characteristic of the AC electric railway is that it is a large-capacity load whose position changes in real time and it generates various harmonics depending on the type of railway vehicle. It causes direct or indirect damage to nearby devices. In this paper, the harmonic generation characteristics according to the running of the railway vehicle were confirmed by measurement at the sectioning post, which is the end of the power feeding system. In particular, the phenomenon of enlarged resonance of harmonics was confirmed through measurement. As a solution, the harmonic resonance suppression effect according to the separation or connection of the R-C bank was compared and presented. |
