Abstract

ABSTRAK ANALISIS FILTER AKTIF SHUNT MENGGUNAKAN FLYING CAPACITOR MULTILEVEL INVERTER UNTUK MEREDUKSI HARMONISA Fajrian Hayyu Anugerah, NIM : 1312046 Dosen Pembimbing I : Prof. Dr. Eng. Ir. Abraham Lomi, MSEE Dosen Pembimbing II : Lauhil Mahfudz Hayusman, ST., MT Harmonisa merupakan gejala pada sistem tenaga listrik berupa distorsi pada gelombang tegangan atau arusnya. Harmonisa yang tinggi memiliki dampak buruk dalam sistem tenaga listrik salah satunya mengakibatkan pemanasan berlebihan pada peralatan listrik yang dialiri arus harmonisa seperti generator, transformator, motor, dan konduktor. Untuk mereduksi harmonisa tersebut digunakan filter aktif shunt metode Flying Capacitor Multilevel Inverter yang bekerja dengan mengambil gelombang arus harmonisa sistem sebagai gelombang referensi, dengan harapan rangkaian Flying Capacitor Multilevel Inverter dapat membangkitkan gelombang dan amplitudo yang sama dengan gelombang harmonisa sistem. Selanjutnya gelombang keluaran dari rangkaian Flying Capacitor Multilevel Inverter tersebut diinjeksikan ke sistem sebagai kompensasi harmonisa. Berdasarkan hasil pengukuran di PT. ADMIRA diperoleh nilai total distorsi harmonisa arus (THDi) yang melebihi standar IEEE 519-1992 yaitu lebih dari 15 persen pada panel spindelis (5” I, 5” II, 9”) dan panel distribusi 3. Setelah dilakukan pemasangan filter aktif shunt metode Flying Capacitor Multilevel Inverter pada panel spindelis (5” I, 5” II, 9”) dan panel distribusi 3 dengan bantuan software PSCAD, menunjukkan filter aktif shunt metode Flying Capacitor Multilevel Inverter mampu mereduksi THDi pada panel spindelis dari 27,02 persen turun menjadi 2,94 persen dan THDi pada panel distribusi 3 dari 48,99 persen turun menjadi 5,96 persen.

Ir. Abraham Lomi, MSEE Second Lecturer : Lauhil Mahfudz Hayusman, ST., MT Harmonics are symptom on electric power system in the form of distortions on voltage or current wave. Higher harmonics has disastrous impacts on electric power systems, one of the impacts is overheating on electrical tools such as generators, transformers, motors, and conductors that flowed by harmonics current. Shunt active filter with Flying Capacitor Multilevel Inverter method is used to reduce the harmonics that works by taking the current harmonics of the system as a reference wave, in the hope Flying Capacitor Multilevel Inverter circuit can generate the same wave and amplitude with the harmonics wave system. Furthermore, the output wave from the Flying Capacitor Multilevel Inverter circuit is injected into the system as harmonics compensation. Based on the measurement results at PT. ADMIRA obtained the total value of current harmonics distortion (THDi) that exceeds the IEEE 519-1992 standard those more than 15 percents on spindelis panel (5" I, 5" II, 9") and third distribution panel. After installed the shunt active filter Flying Capacitor Multilevel Inverter on spindelis panel (5" I, 5" II, 9") and third distribution panel with PSCAD software helps, showing shunt active filter Flying Capacitor Multilevel Inverter capable for reduce harmonics that decreasing THDi on spindelis panel from 27.02 to 2.94 percents and third distribution panel from 48.99 to 5.96 percents.
