Abstract:

High-power winding rotor motor’s doubly fed speed adjusting system is in the use of the structural characteristics of induction motor. The stator flux-oriented is adopted by high-power winding motor, making the motor active power and reactive power components controlled. The software of the rotor frequency vector control algorithm is designed. Then, the rotor frequency vector control algorithm is tested and verified. Under the existing hardware condition in the laboratory, The results of simulation and hardware test show the good control effect.
