Abstract

Beban nonlinear menghasilkan harmonisa yang akan menimbulkan permasalahan misalnya bertambahnya rugi-rugi daya, menurunnya faktor dan kualitas daya, serta dapat menimbulkan kerusakan pada peralatan tersebut maupun peralatan lain. Terminal Intermoda Joyoboyo adalah terminal yang berfungsi sebagai layanan moda transportasi umum seperti bus kota, Suroboyo Bus, angkutan umum, dan bus antarkota. Terminal Intermoda Joyoboyo banyak pengguna dan pegawai menggunakan peralatan bersifat nonlinear yang dapat menimbulkan harmonisa. Inverter yang berperan sebagai filter aktif dipasang secara paralel untuk menghasilkan arus kompensasi harmonisa. Arus ini digunakan untuk menghilangkan arus harmonisa di point of common coupling (PCC). Tegangan dan arus beban digunakan sebagai input dalam perhitungan teori p-q untuk menghasilkan arus anti-harmonisa. Hasil tugas akhir ini menunjukkan bahwa filter aktif shunt yang optimal ditempatkan di beban SDP Lift dan SDP AC, disebabkan nilai arus harmonisa pada lift dan AC tidak memenuhi standar IEEE 519-2022. Nilai THDi sebelum pemasangan filter dari fasa R = 94.21%, S = 88.09%, T = 74.27% menjadi R = 3.22%, S = 3.49%, T = 3.39% setelah pemasangan filter pada beban SDP Lift sedangkan nilai THDi sebelum pemasangan filter dari fasa R = 25.94%, S = 25.92%, T = 24.44% menjadi R = 1.92%, S = 2.19%, T = 2.04% setelah pemasangan filter pada beban SDP AC. Demikian juga dengan nilai TDDi sebelum pemasangan filter dari fasa R = 28.43%, S = 33.79 %, T = 31.24% menjadi R = 0.8%, S = 0.86%, T = 0.84% setelah pemasangan filter pada beban SDP Lift sedangkan nilai TDDi sebelum pemasangan filter dari fasa R = 18.07%, S = 17.94%, T = 18.23% menjadi R = 1.04%, S = 1.18%, T = 1.11% setelah pemasangan filter pada beban SDP AC. Nilai tersebut sudah memenuhi standar IEEE 519-2022. Tidak hanya mengkompensasi harmonisa, filter aktif shunt juga dapat menyeimbangkan kembali arus dari SDP beban serta meningkatkan faktor daya sehingga menunjukkan bahwa performansi dari filter aktif Shunt telah berhasil. Simulasi, hasil dan analisa data menggunakan software MATLAB Simulink.

Nonlinear loads generate harmonics that can cause problems such as increased power losses, decreased power factor and quality, and potential damage to both the equipment generating the harmonics and other equipment. Joyoboyo Intermodal Terminal functions as a public transportation service hub for city buses, Suroboyo buses, public transportation, and intercity buses. Many users and employees at Joyoboyo Intermodal Terminal use nonlinear equipment that can generate harmonics. Inverters acting as active filters are installed in parallel to generate harmonic compensation currents. These currents are used to eliminate harmonic currents at the point of common coupling (PCC). Voltage and load current are used as inputs in the p-q theory calculation to generate anti-harmonic currents. The results of this final project show that the optimal placement of the shunt active filter is on the SDP Lift and SDP AC loads, due to the harmonic current values in the lift and AC not meeting the IEEE 519-2022 standard. The Total Harmonic Distortion of current (THDi) values before filter installation were: phase R = 94.21%, S = 88.09%, T = 74.27%, and after filter installation on the SDP Lift load were: phase R = 3.22%, S = 3.49%, T = 3.39%. Similarly, for the SDP AC load, the THDi values before filter installation were: phase R = 25.94%, S = 25.92%, T = 24.44%, and after installation were: phase R = 1.92%, S = 2.19%, T = 2.04%. The Total Demand Distortion of current (TDDi) values before filter installation were: phase R = 28.43%, S = 33.79%, T = 31.24%, and after installation on the SDP Lift load were: phase R = 0.8%, S = 0.86%, T = 0.84%. For the SDP AC load, the TDDi values before filter installation were: phase R = 18.07%, S = 17.94%, T = 18.23%, and after installation were: phase R = 1.04%, S = 1.18%, T = 1.11%. These values now meet the IEEE 519-2022 standard. In addition to compensating for harmonics, the shunt active filter can also rebalance the current from the SDP load and improve the power factor, demonstrating that the performance of the shunt active filter has been successful. The simulation, results, and data analysis were conducted using MATLAB Simulink software.
