Abstract：

The　harmonic　currents　induced　by　the　traditional　AFD　(Active　Frequency　Drift)　method　for　island　detection　are　analyzed　by　fast　Fourier　transform　and　the　formulas　of　its　third-,　fifth-and　seventh-order　harmonic　currents　are　obtained.　Therefore,　the　currents　with　inverse　phase　can　be　applied　to　compensate　the　harmonic　currents　caused　by　the　AFD　method.　The　way　to　implement　the　AFD　method　with　harmonic　compensation　in　digital　control　system　is　introduced.　Simulative　and　experimental　results　show　that,　the　proposed　method　effectively　reduces　the　harmonic　currents　without　influencing　the　island　detection.
