DC electrified railway line voltage at pantograph often changes according to load condition of other electric vehicles. Vehicle propulsion system is disturbed by this line voltage change. For practical use it must be made clear how the permanent magnet synchronous motor control system for railway traction behaves at line voltage change. In this paper we try to analyze our proposed PMSM control system behavior under sudden change of DC line voltage through pole arrangement and numerical simulation and obtain technical knowledge under this phenomenon.
