틸팅열차시험운행에 따른 차랑전력품질 계측평가에 관한 연구

초록

Test Operation of Tilting Express(TTX) "Hanvit 200" run through Honam Line, Jungang Line, Chunk-buk Line and Taebaek Line to a reliable safety, which train developed in KRRI(Korea Railroad Research Institute). In this paper, we are interested in the electric quality of TTX train on running status, especially, focused on the harmonics. To check and analyze over electric quality of TTX, we are monitored the electric quality included voltage and current harmonics at PT(Ratio 25,000/15/[V]) which is located between pantograph and primary winding of train transformer. By monitoring result, electric quality of train vehicle depend on the mostly running conditions is mean multiplying speed, accelerating speed and braking speed in every test running Line. Especially, voltage THD is above all 3[%] and current harmonics monitored from lowest Harmonic to highest Harmonic in case of multiplying speed or accelerating speed. The results in this paper can help to stabilize the power device and power converter of TTX.
