Analysis of Signals Characterization of Circuits on the Traction Power Systems

摘要

In this paper present the characteristics of the signals and ripple harmonics in the circuits of the traction power systems of the Taipei mass rapid transit system. This analysis provides a novel simulation method, using Matlab software program application to the signals and ripple and harmonics simulate. This investigation uses a reality circuits and systems to simulate the DC traction power system operation for the Taipei metro systems. The analyses discover that the ripple harmonics and operation waveform affect the circuits of the power system design, feature and regulation, and influence on the operation stability of the DC-link between the traction power and vehicle propulsion systems. The simulation data can observe the typical harmonic characteristics for the behavior of the DC traction power systems. This study reveals the running waveforms of the traction power rectifier and vehicle propulsion system operation that can be precise control and regulation. This analysis results of the characteristic of the operation waveform and ripple harmonics in the DC link systems can help engineers to identify system design and after maintenance regulation.
