Modeling, simulation and slip control of a railway vehicle integrated with traction power supply
Studies on the modeling and simulation of the railway vehicle traction system play an active role in the operation and planning phase of railway electrification. In this paper, the longitudinal dynamic of a light rail vehicle was modelled and simulated in Matlab-Simulink. The traction system consists of two parallel motor groups, each of which is composed of two seperately-excited motors connec...
متن کاملRotor Design of IPMSM Traction Motor Based on Multi- Objective Optimization using BFGS Method and Train Motion Equations
In this paper a multiobjective optimal design method of interior permanent magnet synchronous motor ( IPMSM) for traction applications so as to maximize average torque and to minimize torque ripple has been presented. Based on train motion equations and physical properties of train, desired specifications such as steady state speed, rated output power, acceleration time and rated speed of tract...
متن کاملPower Quality Improvement in Traction Power Supply Networks
AC railway traction loads are usually huge single phase loads. As a result, a significant amount of Negative Sequence Current (NSC) is injected into utility grid. Moreover, harmonics and consumption ofreactive power are further power quality problems that the supply network is encountering. In this paper, acompensation strategy with the aid of Railway Power Conditioner (RPC) is proposed to over...
متن کاملModeling for Power Supply Substation in Maglev Train System
Since a power supply substation of the magnetic levitation train system includes an inverter which is necessary to change the frequency of power, it has a different characteristic comparing to any other railway system. Nowadays, a study is undergoing to determine rating of facilities constituting a power supply system and modeling that system. This paper proposes an analysis model for the power...
متن کاملTrain Scheduling Problem - Phase II: A Simulation Integrated Genetic AlgorithmSystem
In [1] a feasible timetable generator stochastic simulation modeling framework for the train scheduling problem was developed to obtain a train timetable which includes train arrival and departure times at all visited stations and calculated average train travel time for all trains in the system. In this study, the framework is integrated with a genetic algorithm (GA) in order to get an optimal...
