Reduksi Harmonisa Pada Uninterruptible Power Supply (UPS) Dengan Single Tuned Passive Filter

ABSTRAK
Penggunaan beban non linier pada Uninterruptible Power Supply (UPS)
mengakibatkan distorsi harmonik yang berdampak pada kwalitas daya. Penelitian ini,
dirancang sebuah single-tuned passive filter untuk mengatasi distorsi harmonik pada
UPS. Pada tahapan ini dilakukan pengukuran THDv, THDi, dan IHDi pada UPS.
Simulasi ujicoba filter menggunakan MATLAB/ Simulink. Setelah pemasangan filter
Single Tuned Passive Filter Nilai arus harmonisa orde ke-3 berkurang dari 47,69 %
menjadi 7,08 % tereduksi sebesar 40,61 %.

ABSTRACT
Using non-linier load in Uninterruptible Power Supply (UPS) can cause
harmonic distortion which will eventually have the effect on power quality. The
research was designed as a single-turned passive filter to cope will harmonic
distortion in UPS. In this phase, THDv, THDi, and IHDi were measured in UPS.
MATLAB/Simulink was used for simulation of filter testing. After single-turned
passive filter was installed, the third order of harmonic current decreased from
47,69% to 7,08% or reduced 40.61%.
