Abstract

Di era modern ini elektronika daya banyak digunakan dalam peralatan listrikyangcenderung bersifat tidak linear, mengakibatkan gelombang arus tidak sama dengangelombang tegangan. Penelitian ini bertujuan untuk mengetahui harmonisa yangditimbulkan oleh BTS yang mencakup tingkat distorsi harmonisa tegangan dan arus akibat pemakain energi listrik pada BTS. Penelitian dilakukan terhadap BTS di Gedung ProgramStudi Teknik Mesin Fakultas Teknik UKI, Jakarta. Berdasarkan penelitian yang dilakukanpada BTS ditemukan bahwa Total Harmonic Distortion Voltage (THDV) untuk fasaR, Sdan T sebesar 1,62%, 1,39% dan 1,34% yang masih memenuhi standar IEEE519-2014, sedangkan nilai Total Harmonic Distortion Current (THDI) untuk fasa R, S dan Tsebesar6,20%, 5,93% dan 5,57% yang tidak memenuhi standar IEEE 519-2014,dengan harmonisadominan terjadi pada orde ke-3. Berdasarkan hasil simulasi rancangan filter aktif shunt menggunakan matlab, diperoleh nilai THDI sesudah menggunakan filter aktif shunt untukfasa R, S dan T bernilai 0,15%, 0,68% dan 0,59% yang telah memenuhi standar IEEE519-2014, serta nilai harmonisa arus dominan menunjukan bahwa orde ke-3 juga memenuhi standar IEEE 519-2014, dengan tingkat harmonisa sebesar 0,01%, 0%dan 0,01%untukfasa R, S, dan T Kata Kunci : Harmonisa, THDI, THDV, Beban tidak linear, Filter Aktif Shunt. / In this modern era, power electronics are extensively used in electrical equipment that tends to be nonlinear, resulting in current waveforms that are not identical tovoltagewaveforms. This research aims to determine the harmonics generated by Base TransceiverStations (BTS), including the levels of voltage and current harmonic distortionduetoelectricity consumption in BTS operations. The study was conducted on BTS units locatedin the Mechanical Engineering Department Building of the Faculty of Engineeringat UKI, Jakarta. Based on the research conducted on the BTS units, it was found that theTotal Harmonic Distortion Voltage (THDV) for phases R, S, and T were 1.62%, 1.39%, and1.34%, respectively, which still meet the IEEE 519-2014 standards. On the other hand, thevalues of Total Harmonic Distortion Current (THDI) for phases R, S, and T were 6.20%, 5.93%, and 5.57%, respectively, failing to meet the IEEE 519-2014 standards, withthedominant harmonics occurring at the 3rd order. Based on the simulation results of thedesigned active shunt filter using MATLAB, the THDI values after applying the activeshunt filter for phases R, S, and T were 0.15%, 0.68%, and 0.59%, respectively, meetingthe IEEE 519-2014 standards. Additionally, the dominant current harmonics for the3rdorder also meet the IEEE 519-2014 standards, with harmonic levels of 0.01%, 0%, and0.01% for phases R, S, and T. Keywords: Harmonics, THDI, THDV, Nonlinear Load, Active Shunt Filter
