Abstract

Dalam pengoperasian sistem tenaga listrik, pihak penyedia atau grid memiliki kewajiban untuk menjaga kualitas daya dari harmonisa arus sistem dan nilai faktor daya. Untuk mengatasi masalah kualitas daya tersebut, berbagai jenis kompensasi telah digunakan seperti contohnya adalah Shunt Active Power Filter (SAPF). Dalam penelitian ini akan dilakukan pemodelan SAPF dengan objek IEEE 33-Bus termodifikasi yang menggunakan level tegangan 12,66 kV dan penelatakan SAPF di titik Point of Common Coupling (PCC). Pada penelitian ini akan digunakan beberapa skenario dalam pemodelan beban nonlinear untuk menguji kinerja SAPF. Skenario tanpa modifikasi sebagai base case, peningkatan beban nonlinear secara bertahap dari 25% hingga 100% untuk menguji ketahanan SAPF, dan beban nonlinear tidak seimbang. Pemodelan SAPF akan menggunakan MATLAB-Simulink. Hasil peredaman THD arus dan kompensasi daya reaktif untuk perbaikan faktor daya akan diperhatikan menggunakan standar IEEE 519 dan SPLN 70-1 untuk setiap skenario yang digunakan. Pada skenario base case didapatkan peredaman THD arus dari 15,5% menjadi 1,08% dan perbaikan faktor daya dari 0,673 lagging menjadi 0,999 lagging. Selain itu, ketahanan dari SAPF yang dimodelkan untuk skenario base case dapat bertahan sampai kenaikan beban nonlinear 65% dan pada peningkatan 100% sudah tidak beroperasi optimal. Pada percobaan beban nonlinear tidak seimbang, rasio ketidakseimbangan arus menurun dari 12,02% dari 4,65% pada ketiga fasanya setelah pemasangan SAPF.

In the operation of electric power systems, the provider or grid operator is responsible for maintaining power quality by managing current harmonics and power factor values. To address these power quality issues, various types of compensation methods have been utilized, such as the Shunt Active Power Filter (SAPF). This research involves modeling an SAPF with a modified IEEE 33-Bus system using a voltage level of 12.66 kV and placing the SAPF at the Point of Common Coupling (PCC). Several scenarios will be used in modeling nonlinear loads to test the performance of the SAPF. The scenarios include a base case without modifications, a gradual increase in nonlinear loads from 25% to 100% to test SAPF resilience, and unbalanced nonlinear loads. The SAPF modeling will be conducted using MATLAB-Simulink. The results for the reduction of current Total Harmonic Distortion (THD) and reactive power compensation for power factor improvement will be evaluated using IEEE 519 and SPLN 70-1 standards for each scenario. In the base case scenario, the current THD is reduced from 15.5% to 1.08%, and the power factor is improved from 0.673 lagging to 0.999 lagging. Additionally, the modeled SAPF shows resilience up to a 65% increase in nonlinear load, but at a 100% increase, it no longer operates optimally. In the unbalanced nonlinear load experiment, the current imbalance ratio decreases from 12.02% to 4.65% across all three phases after installing the SAPF.
