Abstract Based on the fundamental principle of multiple-average harmonic analysis, a novel algorithm for harmonic measurement is proposed, with which the amplitude and phase of the harmonics can be calculated accurately and conveniently. Its accuracy has been verified by computer simulation and physical experiment described. Further, the influence of noise at samples to the result has been discussed by Monte Carlo method and a qualitative result for practical engineering application is given.
