Description
Summary:Considering the features of the load, such as time-varying and randomness, it is hard to estimate the harmonic impedance. The computing method of harmonic impedance is proposed with the system-side harmonic fluctuation dominated, while the phase angle is taken into account, which improves the accuracy of the calculation. At the same time, this paper adopts the idea of piece-wise linear regression to decrease the influence of unusual data on the estimation results. Finally, the theoretical validity and application feasibility are verified by an example analysis.
