Abstract

Dalam dunia kelistrikan ada 2 cara penyaluran daya, yaitu dengan sistem AC dan DC. Dalam sistem DC berbagai peralatan yang digunakan cukup berbeda daripada sistem AC dan komponen terpenting dalam sistem transmisi DC ialah konverter 12 pulsa. Namun konverter yang digunakan menimbulkan masalah kualitas daya yaitu munculnya arus harmonisa, dimana harmonisa sangat merugikan karena dapat mengakibatkan panas yang berlebih pada peralatan. Arus harmonisa mengakibatkan tegangan juga terdistori seiring arus yang lewat juga tidak murni sinusoidal.Dalam tugas akhir ini melakukan simulasi harmonisa pada bus-bus sistem interkoneksi pada backbone transmisi guna mengetahui nilai harmonisa baik pada masing –masing sistem kelistrikan tetapi juga pada bus-bus sistem backbone itu sendiri dan membendingkan hasilnya sebelum dan setelah penambahan peralatan filter pasif. Filter pasif tipe single tune dan high pass type C mampu secara efektif meredam level harmonisa pada sistem secara menyeluruh tidak hanya pada satu frekuensi tertentu, melainkan frekuensi yang lebih tinggi juga. Dimana hasil yang didapatkan ialah pada bus Samarinda Rec THDV menjadi 1.08, Balikpapan Inv THDV menjadi 1.04, Balikpapan Rec THDV menjadi 0.97, dan Pontianak Inv THDV menjadi 0.86. =============================================================================================== In the electricity area there are 2 different ways to transmit the power energy, there are AC and DC system. On DC system there are different devices compare with AC system, and most important device is 12 pulse converter. But, converter make some power quality disturbance in harmonic area, harmonic are to dangerous because it can result overheating to the devices. Harmonic current can impact to harmonic voltage athough the current wave not even sinusoidal. This final project simulate harmonic and investigate the harmonic level on transmission backbone bus and all sistem buses and compare level harmonic bafore and after passife filter installation. Passife filter single tune type and high pass type C can reduce harmonic level effectively, it could reduce harmonics not only in one frequency, but higher frequency too. Where the results that we get are THDV Samarinda Rec became 1.08, THDV Balikpapan Inv became 1.04, THDV Balikpapan Rec became 0.97, and THDV Pontianak Inv became 0.86.
