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%.

Keywords : Single-Turned Passive Filter, UPS Harmonics, One Phase Harmonic
