Abstract

Di era modern ini elektronika daya banyak digunakan dalam perlatan listrik yang cenderung bersifat tidak linear, mengakibatkan gelombang arus tidak sama dengan gelombang tegangan. Penelitian ini bertujuan untuk mengetahui harmonisa yang ditimbulkan oleh BTS yang mencakup tingkat distorsi harmonisa tegangan dan arus akibat pemakain energi listrik pada BTS. Penelitian dilakukan terhadap BTS di Gedung Program Studi Teknik Mesin Fakultas Teknik UKI, Jakarta. Berdasarkan penelitian yang dilakukan pada BTS di temukan bahwa THDV untuk fasa R, S dan T sebesar 1,62%, 1,39% dan 1,34% yang masih memenuhi standar IEEE 519-2014, sedangkan nilai THDI untuk fasa R, S dan T sebesar 6,20%, 5,93% dan 5,57% yang tidak memenuhi standar IEEE 519-2014, dengan harmonisa dominan terjadi pada orde ke-3 sebesar 4,76%, 4,61% dan 4,65% untuk fasa R, S dan T. Berdasarkan hasil perhitungan, diperoleh nilai TPF untuk fasa R, S dan T sebesar 0,93, 0,75 dan 0,96, untuk fasa R dan T memenuhi standar faktor daya PLN, sedangakn fasa S tidak memenuhi. Berdasarkan hasil simulasi rancang filter aktif shunt menggunakan matlab, diperoleh nilai THDI sesudah menggunakan filter aktif shunt untuk fasa R, S dan T bernilai 0,15%, 0,68% dan 0,59% yang telah memenuhi standar IEEE 519-2014, 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% untuk fasa R, S dan T. Kata kunci: Harmonisa, THDI, THDV, Beban nonlinier, Filter Aktif shunt. / In the modern era, power electronics are widely used in electrical equipment that tends to be nonlinear, resulting in current waves that are not the same as voltage waves. This research aims to determine the harmonics generated by BTS, including the level of harmonic distortion of voltage and current due to the usage of electrical energy at the BTS. The research was conducted on the BTS in the Mechanical Engineering Program Building, Faculty of Engineering UKI, Jakarta. Based on research conducted on BTS, it was found that the THDV for phases R, S and T are 1,62%, 1,39% and 1,34%, which still complies with the IEEE 519-2014 standard. However, the THDI values for phases R, S and T are 6,20%, 5,93% and 5,57%, which do not meeet the IEEE 519-2014 standard, with the dominant harmonics occuring at the 3rd order are 4,76%, 4,61% and 4,65% for phase R, S and T. Based on the calculation results, the TPF values for phases R, S and T are 0,94, 0,75 and 0,96, respectively phases R and T comply with the PLN power factor standard, while phase S does not comply. Based on the simulation results of the designed active shunt filter using MATLAB, the THDI values after using the active shunt filter for phases R, S and T are 0,15%, 0,68% and 0,59%, which meet the IEEE 519-2014 standard. The dominant current harmonics alse meet the IEEE 519-2014 standard, with harmonic levels of 0,01%, 0% and 0,01% for phases R, S and T. Keywords: Harmonics, THDI, THDV, Non-linear load, Shunt Active Power Filter.
