Abstract
Penelitian lebih lanjut untuk menganalisis harmonisa pada keluaran inverter PLTS dengan berbagai konfigurasi dan kondisi operasi. Oleh karena itu, penelitian ini bertujuan untuk menganalisis harmonisa pada keluaran inverter PLTS menggunakan Multisim, sehingga dapat memberikan kontribusi dalam meningkatkan efisiensi sistem PLTS. Tujuan penulis melakukan penelitian adalah: mengetahui tingkat harmonisa arus dan tegangan pada sisi keluaran inverter PLTS on-grid, dan merancang rangkaian filter aktif low pass berdasarkan tingkat harmonisa pada sisi keluaran inverter PLTS on-grid yang mengacu standar IEEE 519-2014 menggunakan Multisim. Berdasarkan hasil simulasi rangkaian filter aktif low pass diatas, diperoleh Kesimpulan yaitu: dari hasil pengukuran, diperoleh bahwa THD-v pada sisi keluaran inverter PLTS on-grid sebesar 1,55% masih dibawah nilai batas standar IEEE, dan nilai THD-i sebesar 5,38% melebihi standar IEEE 519-2014, Dan diperoleh THD-i dominan orde 3 sebesar 4,09%, dengan memperhitungkan THDv dan THDi, maka diperoleh TPF 0,83, belum memenuhi standar faktor daya ≥ 0,85, Setelah dilakukan simulasi Multisim, filter aktif dapat mereduksi THD-i menjadi 2,063%, sesuai standar dan faktor daya menjadi 0,94. Kata kunci: inverter, harmonisa, Multisim, PLTS, THD Further research to analyze harmonics at the output of the PLTS inverter with various configurations and operating conditions. Therefore, this study aims to analyze harmonics at the output of the PLTS inverter using Multisim, so that it can contribute to increasing the efficiency of the PLTS system. The author's objectives in conducting the research are: to determine the level of current and voltage harmonics at the output side of the on-grid PLTS inverter, and to design a low-pass active filter circuit based on the harmonic level at the output side of the on-grid PLTS inverter referring to the IEEE 519-2014 standard using Multisim. Based on the simulation results of the low pass active filter circuit above, the following conclusions are obtained: from the measurement results, it is obtained that the THD-v on the output side of the on-grid PLTS inverter of 1.55% is still below the IEEE standard limit value, and the THD-i value of 5.38% exceeds the IEEE 519-2014 standard, and the dominant THD-i of order 3 is 4.09%, taking into account THDv and THDi, the TPF is 0.83, which does not meet the power factor standard ≥ 0.85. After the Multisim simulation, the active filter can reduce THD-i to 2.063%, according to the standard and the power factor to 0.94. Keywords: inverter, harmonics, Multisim, PLTS, THD
