Abstract This paper proposes a method of variable-frequency motor harmonic suppression based on variable-inductance reactor. Firstly, a co-simulation model was built. It achieves the control system of the variable-frequency motor and solves the problem of field-circuit coupling under vector control. Secondly, the controllable reactor, the control strategy and the harmonic suppression program were designed. The detection of stator current harmonics is completed by the instantaneous reactive power law. When the load torques change, the system matches an appropriate reactance rate for the reactor to suppress harmonic of a particular order and the harmonics order above it according to the detected harmonic information. At last, the simulation and experiment were carried on. The simulation and experiment results show that the method of harmonic suppression based on variable-inductance reactor is effective.

Key words： Variable-frequency motor controllable reactor vector control harmonic suppression
