A Method for Responsibility Division of Multi-Harmonic Sources Based on Canonical Correlation Analysis

The variable background harmonic data and incomplete phasor information make multi-harmonic source responsibility division in three-phase symmetrical power system a significant challenge. In this paper, selection method based on canonical correlation analysis is proposed to deal with without information. Firstly, the coefficient between voltage current used characterize fluctuations of voltage. Then, sliding window adopted select small fluctuations. Next, results for selected are calculate index via linear regression method. form percentage represents division. Finally, several experimental demonstrate that has high accuracy calculating division, particularly when user side contains unknown sources.
