【 摘 要 】

This paper used the gradient blind signal separation algorithm to carry out the electrical power system harmonic signal analysis through the simulation experiment. The experiment result proved that the electrical power system harmonic signal separation based on the gradient algorithm is accurate. Through comparing the separation performance by using the different step size, the adaptive changing step size natural gradient blind separation algorithm for the electrical power system harmonic signal blind source separation can effectively separate each frequency harmonic component of the observation blind mixed signal. This paper mainly analyzed the algorithm performance of convergence speed and steady state error under the selection of different step size.
