Abstract

Tugas akhir ini membahas pengaruh arus eksitasi terhadap daya reaktif di PT. Indonesia Power UPJP Kamojang. Fokus penelitian adalah fluktuasi arus eksitasi dan daya reaktif serta hubungan antara keduanya. Tujuannya adalah untuk mengetahui fluktuasi arus eksitasi dan daya reaktif dan pengaruh arus eksitasi terhadap daya reaktif. Arus eksitasi berbanding lurus daya reaktifnya. Nyatanya, arus eksitasi dan daya reaktif tidak selalu berbanding lurus. Penelitian ini menyimpulkan bahwa semakin besar IF maka Ea pun semakin besar. Di bagian fasa R pada posisi IF=418,6 A yang sebelumnya adalah IF=405,1 A bernilai Ea=12,2777 kV yang sebelumnya Ea=12,2637 kV ada kenaikan IF sebesar 3,23% dari arus eksitasi sebelumnya serta terdapat perubahan IF sebesar ±7,43 A. Nilai VT cenderung konstan karena menjaga sinkronisasi dengan sistem, yaitu sebesar 11,814 kV menjadi 11,8216 kV. Ada kenaikan tegangan 0,064% dari tegangan sebelumnya serta terdapat perubahan VT sebesar ±0,00768 kV. Kenaikan Ea sebesar ±0,0096 kV, kenaikan Ea tersebut menyebabkan kenaikan sebesar 0,64% dari tegangan jala-jala sebelumnya. Fluktuasi Q akibat perubahan IF berkisar 6,128% dengan perubahan Q sebesar ±0,501 MVAR. Liniernya nilai arus eksitasi terhadap daya reaktif 70,59%. Selain bagian fasa R, fasa S dan fasa T pun memiliki kondisi fluktuasi yang mirip dengan fasa R.

The last of these duty discuss the effect of the excitation current against reactive power in PT. Indonesia Power UPJP Kamojang. The focus is the current study fluctuations excitation and the reactive power as well as the relations between them. The goal is to find fluctuations the current excitation and the reactive power and the effect of the current excitation against the reactive power. The current excitation directly proportional to the reactive power. In fact, the current excitation and the reactive power not always directly proportional. This study concluded that the bigger IF so Ea is large. At the phase R in a position IF = 418,6 A which was previously IF = 405,1 A worth Ea = 12,2777 kV formerly Ea = 12,2637 kV surge IF of 3.23 % of the current excitation formerly and there was a change in IF of ±7,43 A. The value VT tending to constant because keep synchronization with the system , Is as much as 11,814 kV be 11,8216 kV. Surge voltage 0,064 % of voltage formerly and there was a change in VT of ±0,00768 kV. The increase in Ea of ±0,0096 kV , the increase in Ea cause increase of 0,64 % of voltage network before. Fluctuations Q resulting from a change if range 6,128 % with change Q of ±0,501 MVAR. The linear value current excitation to power reactive 70,59 %. Besides part in phase R , the phase S and the phase T may have condition fluctuations that similar to the phase R .
