Abstract

This paper introduces a method using second order blind identification (SOBI) algorithm to analyze he voltage flicker signal. An embedded matrix is constructed as the multi-channel input signals. Robust whitening is used to reduce noise and decompose data onto the signal subspace. The SOBI algorithm is used to separate the source signals and get the frequency and amplitude of the voltage flicker. Simulation results show that the proposed method based on SOBI algorithm can rapidly and accurately separate the source signals from the voltage flicker.
