Modeling and Simulation of Traction Power Supply System for High-Speed Maglev Train

The electromagnetic suspension high-speed maglev train system uses long-stator linear synchronous motors (LLSMs) as levitation and traction mechanisms. In this paper, the modeling simulation of power supply for are performed. models include transformers, converters, variable-length cables LLSMs both two sides ends; meanwhile, corresponding control segmented strategies, including two-step method three-step method, implemented. Based on model, operational performance is verified, fault performances under open circuit short also analyzed. whole results have important reference significance research technology.
