Abstract
Unlike the effects of other power quality and harmonics, which are caused by electromagnetic interference, such as electrical characteristics, due to the nature of railway transport, research is progressing steadily.
Since the introduction of the electric railway system for continuous power quality surveys is underway, each device is under consideration for the influence of the current harmonics of the device on the railway car.
In this thesis, the causes of the harmonics of the power system was investigated. The counter measures for such harmonics are described in terms of the voltage fluctuation from contact with the current collector input power In particular, the main power flowing through the input stage inverter is measured. The harmonic analysis is also performed by analyzing the input power of the input rail and the input power of each unit. The validity of the current through the software of the gain controller indicates the validity of the filter design. The main power converter was verified by a manual reset of the filter. As a result, by increasing the harmonic generation and resonance phenomena of the power converter for high-speed railway vehicles that convert the power and influence of the switching power converter and the main-pass harmonic filter. It is possible to reduce the resonant phenomenon by setting the resonant rising to an error. The main power conversion unit confirms that harmonics can be reduced by redesigning the filter converter to reset the converter's inverter and converter software.
