Cophase Traction Power Supply System Based-MMC-Vv Wiring
نویسندگان
چکیده
A new homogeneous traction power supply scheme based on Vv wiring transformers and modular multilevel converters (MMC) is proposed, which due to address the electrical quality problems negative effects of splitting locomotives in electrified railways. The three-phase converter this paper adopts MMC-based active compensator (APC), can eliminate bridge arm one phase step-down isolation transformer compared with conventional single-phase back-to-back structure converter. compensation relationship each port APC derived, dynamic control strategy established, equalization shifting carrier techniques are applied them achieve target. Finally, MATLAB/Simulink employed as a platform build model for simulation, experimental results verify feasibility strategy.
