A Study on Motor Temperature Characteristic in Running Test

초록

The rolling stock (RS) of electric railway has been popular as public transport means for its high energy efficiency as well as the advantage that corresponds with government's low-carbon green growth policy. About 70% of domestic railway network has been electrified, which is expect to reach around 86% in 2020. The demand for RS of electrical railway has been on the rise to take the most part of passenger transport. Good quality power energy shall be supplied for stable operation of electrical railway. However the load of electrical railway tends to move with the passage of time and using the momentary high power and transmission of regenerative breaking energy to the wire by using power semiconductor element has deteriorated the electric power quality of railway.
