Abstract :
This letter proposes a novel phase-angle measurement algorithm through establishing a mathematical model of virtual αβ stationary coordinate that utilizes two expression forms of a positive-sequence component in two axes stationary reference frame. This method could greatly eliminate the sinusoidal error of the conventional discrete Fourier transform (DFT) algorithm. The accuracy and performance of the proposed algorithm are proved by relevant simulation results.
