In order to reduce the influence of sudden increase of load on harmonic current identification

in this paper

a kind of harmonic detection method based on i

-i

model with double moving average filters algorithm is proposed. The mathematical model of moving average filter is established;the existenceform of harmonic after dq transformation is deduced

thus pointing superiority of double moving filtering method on the harmonic detection.The SIMLINK is used to set up load zero switchingmodels with and without harmonic condition

and the harmonic current on the trunk line in the switching of grid network is simulated. It is shownbytheresultthattheuseofdoublemovingaverage

filterimprovesthefastperformanceoftheharmonic current detection and assures the accuracy of harmonic current detection

which can adapt to dynamic and steady state process and enhance system robustness and reliability.
