摘要：

Harmonic contribution determination is the premise on which the improvement of power system harmonic management is based. Calculating the harmonic impedance accurately is the key issue in harmonic contribution determination. The fluctuation method is a mature method for calculating the harmonic impedance in engineering applications. However, this method is ineffective when the background harmonic fluctuation is dominant. To make up the deficiency of the fluctuation method, the partial linear regression model for the harmonic impedance calculation is proposed in this paper, and then a two-stage method is derived for the unbiased estimation of the model. The method proposed in the paper can calculate the harmonic impedance whether or not the background harmonic fluctuation is dominant, and then the harmonic contribution can be determined. The effectiveness of the proposed method is verified by the IEEE14-bus system simulation and field test. (c) 2016 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
