Abstract
PT. Semen Indonesia merupakan salah satu perusahaan dalam negeri
yang bergerak di bidang produksi semen. PT. Semen Indonesia sedang
mendirikan pabrik baru di Aceh. PT. Semen Indonesia menggunakan
motor-motor induksi dalam proses produksi semen. Untuk
mengendalikan kecepatan putaran motor-motor induksi tersebut
diperlukan VFD (Variable Frequency Drive). VFD merupakan salah satu
beban non linear sehingga penggunaanya akan menimbulkan munculnya
harmonisa pada sistem kelistrikan di pabrik ini. Harmonisa jika dibiarkan
terus-menerus akan menimbulkan masalah pada peralatan listrik lainnya
seperti transformator, motor, dan kabel. Masalah-masalah tersebut pada
akhirnya berujung pada kerugian ekonomi. Oleh karena itu perlu
dilakukan studi harmonisa dan mitigasi untuk mengurangi harmonisa
pada PT. Semen Indonesia Pabrik Aceh.
Mitigasi harmonisa dilakukan dengan pemasangan filter single
tuned. Filter yang dipasang berhasil meredam harmonisa dan
memperbaiki faktor daya. Nilai THD V dan THD I di bus MV dibawah
5%. Simulasi dan analisis dilakukan dengan menggunakan software
ETAP 12.6.

PT. Semen Indonesia is one of the domestic companies that engaged
in the production of cement. PT. Semen Indonesia is creating a new plant
in Aceh. PT. Semen Indonesia using induction motors in the cement
production process. For controlling the rotational speed of induction
motors required VFD (Variable Frequency Drive). VFD is one of the non -
linear load so that its use will lead to the emergence of harmonics on the
electrical system in this plant. Harmonics if allowed to continue will cause
problems on other electrical equipments such as transformers, motors, and
cables. Those problems eventually lead to economic losses. It is t herefore
necessary to study harmonics and mitigation to reduce harmonics at PT.
Indonesia Aceh cement plant.
Mitigation of harmonics has been done with the installation of a
single tuned filter. Installled filter succesfully dampen harmonics and
improve the power factor. THD V and THD I values in MV bus is below
5%. Simulation and analysis conducted using software ETAP 12.6.
