[Paper Title, Abstract] Improving the Power Quality of Traction Power Systems with a Single-feeding Wire Show AbstractHide Abstract A topology for traction power systems with a single feeding wire, which consists of a three-phase V/V transformer and a three-phase converter, is proposed at first and then a control strategy based on the repetitive control is developed to deal with the power quality issues in the system. Because of the repetitive controller, all the harmonic and negative sequence currents generated by locomotives, which are single phase nonlinear loads, are compensated and only the active power is drawn from the grid. Different from the commonly used hysteresis controllers in traction power systems, the repetitive controller has a fixed switching frequency, which reduces the stress on the power semiconductor devices. Simulation results are provided to illustrate the performance of the system. [Schedule] TTA-GWRB [Category :: Sub-Category]
