Sensitivity Analysis of Characteristic Parameters of Railway Electric Traction System
The modal analysis, which decouples the contact wire and rail track conductors, is used to develop an integrated model of single rail track and contact wire. The characteristic impedance and propagation constant matrices of integrated model have been computed. The authors have studied effects of various parameters of interest on characteristic impedance and propagation constant using sensitivit...
متن کاملExperiment System of Motorcycle Impact Injury Using Electric Motor Traction
Although motorcycle crash is one of the most common causes of death and injury, there hasn’t been a standard experiment system to simulate the generation of the resulting motorcycle impact injuries. A unique motor drive unit (MDU) and motorcycle crash simulation unit (MCSU) were developed to establish a short-track and high-accuracy experiment system of motorcycle impact injury. The control har...
متن کاملAnalysis of Harmonics of Electric Traction System using Wavelet Transform
Wavelet Transform is a mathematical tool for time frequency analysis of non stationary signals like the current waveform in electric traction system. The locomotives used in traction system have different types of traction motors –dc and three phase ac motors with different methods of speed control. Hence technologies will be different depending on the type of locomotives. The nature of the loa...
متن کاملHarmonic Disturbance Compensating and Monitoring in Electric Traction System
This paper presents methods to compensate and monitor the disturbance generated by electric traction units, considering their position in different times, in a railway system. For this purpose, first of all, experimental data of Italy traction system is used and its components are modeled. Then, using proposed algorithm a suitable location for a passive filter is determined. Subsequently, consi...
متن کاملOvercoming the Challenges of Hybrid/Electric Vehicle Traction Motor Design
tight market windows in the rapidly evolving HEV and EV markets. Integrated multiphysics simulation technology helps to address these challenges by enabling engineers to rapidly evaluate — prior to physical prototyping — functionality, performance and cost of a wide range of design alternatives. This approach makes it possible to optimize traction motor design performance in a fraction of the t...
