HARMONIC ANALYSIS AND ITS COUNTERMEASURE

초록

These days, KNR has many construction projects of electrification. There are harmonic problems in construction of AC 25kV-60Hz electric railway. To solve them, we have analyzed a harmonic characteristic of AT power supply system. We have found out harmonic countermeasure. This paper presents three kinds of model for harmonic analysis and three cases of harmonic countermeasure for electrified conventional line
