Research on sequence component detection algorithm based on sliding-window mean-value

Aiming at the shortcoming of traditional time domain sequence component detection algorithm, a kind of Fourier analysis algorithm of sliding-window mean-value in frequency domain was put forward. Symmetrical component method was used in calculating the sequence component of the fundamental phasor in this algorithm after using the calculation of continuous average sliding-window of Fourier analysis to separate the real component and the imaginary component of the fundamental phasor from three input signals. The Matlab simulation indicated that using sequence component detection algorithm based on sliding-window mean-value had high accuracy and satisfying real-time, dynamic performance stability.
