| Abstract: | Based on instantaneous reactive power theory, the following paper introduces an improved harmonics current testing method. It can test harmonics current in a state of unbalanced grid and let active filter only compensate harmonics current in the works. This method also fits for harmonies current testing in a state of balanced grid. |
