dc.description.abstract | Most of the tools that used as speed control of three phase induction motors rotation
is 1 phase Variable Speed Drive (VSD), where VSD is a harmonic generator.
Therefore the harmonics that arise in the VSD can be reduced by using passive LC
filters fasif namely passive single tuned filter that meet the standards IEC61000-3-2
Class A.The results obtained through passive LC filter could reduce the total
distortion of harmonic current (THDi) from 102.9% to 23.78% while passive single
tuned filter reduced the total harmonic distortion current (THDi) from 102.9% to
8.79%. At the fifth harmonics passive LC filters could reduce the harmonics current
from 1.26 Ampere to 0.16 Ampere, while passive single tuned filter could reduce the
harmonic current from 1.26 Amper to 0.111 Amper. The impedance produced by
passive single tuned filters was smaller that is 0.436 Ω while passive LC filters was
8.34 Ω . There by passive single tuned filter is better to reduce harmonics than
passive LC filters is. | en_US |
dc.description.abstract | Sebagian besar alat yang digunakan sebagai pengatur kecepatan putaran motor
induksi tiga fasa adalah Variable Speed Drive (VSD) 1 fasa, di mana VSD
merupakan pembangkit harmonisa. Oleh sebab itu harmonisa yang timbul pada VSD
dapat direduksi dengan menggunakan filter fasif yaitu passive LC filter dan passive
single tuned filter sehingga memenuhi standar IEC61000-3-2 kelas A. Hasil yang
diperoleh dengan passive LC filter dapat mengurangi total distorsi harmonisa arus
(THDi) dari 102,9% menjadi 23,78% sedangkan passive single tuned filter
mengurangi total distorsi harmonisa arus (THDi) dari 102,9% menjadi 8,79%. Pada
harmonisa ke 5 passive LC filter dapat mengurangi harmonisa dari 1,26 Amper
menjadi 0,16 Amper , sedang passive single tuned filter dari 1,26 Amper menjadi
0,111 Amper. Impedansi yang dihasilkan passive single tuned filter lebih kecil yaitu
0,436 Ω sedang passive LC filter 8,34 Ω. Dengan demikian passive single tuned
filter lebih baik untuk mereduksi harmonisa dibandingkan dengan passive LC filter. | en_US |
