Research on Variable Speed System of Three-Level Double-fed Motor
Abstract：Three-level double-fed motor control system can adjust the stator side reactive power and improve system stability.The topology structure and control principle frame diagram of three-level double-fed motor speed system and the mathematical model of two-phase rotating coordinate is derived in the two-phase rotating coordinate system.The control theory of vector control system based on the stator flux orientation and rotor current control is adopted.Simulation model of three-level vector control system of double-fed motor is built and simulated using Matlab/Simulink.The control scheme is verified correctly and validly via simulation results and the theoretical base of practical motor control system＇s designing and debugging is established.
Keywords：three-level double-fed motorstator flux orientationvector control
