Existing problems： Large voltage and current distortion rate;
The main harmonic currents were 5th, 7th, 11th, 13th, the total current distortion rate was as high as 30%, and the system power quality was poor;
ZAPF active power filtering device of SSE was used to filter the system harmonics.
Control effect： Voltage distortion droped from 5.5% before controlling to 1.3% , and the current distortion droped from 28.3% before controlling to 6.5% ; The 5th, 7th, 11th harmonic currents droped from 25%, 5.2%, 2.3% before controlling to 4.8%, 1.0%, 0.5% ,the filtering effect was significant. Power factor reached over 0.92 after controlling.
