KHST 차량 전기장치의 본선시운전시험에 관한 연구

KHST(Korean High-Speed Train, 350㎞/h), composed of 7 cars that are 2 power cars, 2 motorized car and 3 trailer cars, has been developed and is under on-line test. To verify hte design requirements about the functions and traction performances of this train, KRRI(Korea Railroad Research Institute} decided to evaluate traction performances of the train during on-line test. For this purpose, such as torque, velocity, voltage and current, must be measured. KRRI has developed the measurement system that can be measured vast and various signals effectively. In this paper, we introduce traction performances of KHST. The traction measurement items are focused on the verification of motor block performances.
