PERFORMANCE EVALUATION OF AUXILIARY CONVERTER FOR HIGH SPEED TRAIN

초록

KHST(Korean High Speed Train) has been developed by KRRI (Korea Railroad Research Institute) for last 7 years to satisfy the need. An electric railway system is composed of high-tech subsystems, which consists of electric equipment such as transformers and converters, which are critical components determining the performance of rolling stock. We developed a measurement system for on-line test and performances evaluation for KHST. The measurement system is composed of both software and hardware components. Perfect interface between multi-users is possible. A new method to measure temperature was applied to the measurement system. By using the system, fault diagnosis and performance evaluation of electric equipment in Korean High Speed Train was conducted during test runs."
