【 摘 要 】

An optimized reference current detection method based on synchronous reference frame transformation and sliding discrete Fourier transform (SDFT) is proposed. The proposed method can be used to extract characteristic harmonic currents as the reference current of system from the load currents by fewer sampling points, meanwhile, the numbers of harmonics need to be calculated will reduce to half of traditional method, it means that the proposed method can reduce the computational effort and easy to engineering implementation, while achieving better dynamic performance compared with other methods. The results of simulation and experiment show the validity of this method.
