Line-current harmonics and grid stability are major concerns for the control of a traction vehicle line-side converter. To achieve best dynamic performance the resonant circuit taking up the single-phase power pulsation has to be considered. This paper describes the derivation of a linear-quadratic (LQ)-optimized multivariable control fulfilling these(More)
Actually, AC 16.7-Hz railway grids are fed via back-to-back converters from the public grid. A flux-based multivariable control for the three-phase-side converter is presented, which takes the resonant circuit of the single-phase-side converter into account, leading to excellent stationary and dynamic behaviour.
A project is presented, in which four-quadrant converter, resonant tank and machine-side inverter of a railway traction vehicle operating at single-phase 16.7 Hz are treated as one unit, featuring an integrated model-based control of all quantities. The project aims at improving the dynamic behaviour of the overall system.
