Abstract

Lombok merupakan salah satu destinasi wisata nasional. Untuk itu, pemenuhan terhadap kontinuitas pelayanan listrik menjadi hal krusial yang harus dipenuhi untuk mendukung pariwisata ini. Salah satu parameter yang harus dijaga di dalam sistem tenaga listrik adalah parameter tegangan. Nilai tegangan dapat berfluktuasi akibat terjadinya gangguan pelepasan pembangkit atau saluran transmisi, sehingga menimbulkan perubahan kualitas tegangan. Mengacu pada permasalahan ini, analisis stabilitas tegangan dan kontingensi diperlukan dalam memastikan kestabilan sistem tenaga. Pada penelitian ini akan dianalisis batas maksimal maksimal pembebanan pada bus 150 kV dengan menggunakan metode kurva P-V dan kurva Q-V. Selain itu, diurutkan peringkat Performansi Indeks (PI) dari kontingensi saluran N-1 dan N-2 untuk beban rendah, beban puncak siang, beban puncak malam tahun 2022 dan 2023. Dari hasil simulasi kestabilan tegangan didapatkan nilai batas maksimal maksimal pembebanan pada bus 150 kV masih berada dalam batas aman yaitu 348,414 MW pada bus Jeranjang saat kondisi beban puncak malam tahun 2023. Untuk kondisi tegangan minimum sebelum collapse sebesar 0,64 p.u (Per Unit) yang masih jauh di bawah standar PLN yaitu 0,9 p.u. Sedangkan hasil simulasi kontingensi saluran transmisi N-1 tidak menimbulkan pelanggaran terhadap batas tegangan yang diizinkan. Ketika kasus kontingensi saluran N-2 terdapat beberapa Gardu Induk yang putus dari sistem kelistrikan antara lain Kuta, Mataram, Sengkol, Tanjung, Mantang, dan Sekotong. Sehingga perlu direncanakan penambahan saluran agar G.I tersebut tidak kehilangan kontinuitas aliran listrik, terutama pada G.I Kuta yang merupakan salah satu pusat wisata.

Lombok is a national tourist destination. One of the leading tourist attractions on Lombok Island is the Mandalika Circuit and Kuta beach. For this reason, fulfillment of the continuity of electricity services is a crucial thing that must be fulfilled to support this tourism. One of the parameters that must be maintained in the electric power system is the voltage parameter. The voltage value can fluctuate due to disturbances in the release of generators or transmission lines, causing changes in the quality of the voltage. Referring to this problem, analysis of voltage stability and contingency is needed to ensure the stability of the power system. This research will analyze the maximum power transfer limit on the 150 kV bus using the P-V curve and Q-V curve method. In addition, the Performance Index rankings of N-1 and N-2 line contingencies are sorted for low load, peak day load, and peak night load in 2022 and 2023. From the simulation results of voltage stability, it is obtained that the maximum power transfer limit value on the 150 kV bus is still safe limits, 348.414 MW on the Jeranjang bus during peak night load conditions in 2023. For minimum voltage conditions before collapse, it is 0.64 p.u which still far below the PLN standar of 0.9 p.u. Meanwhile, the contingency simulation results for the N-1 transmission lines did not cause any violation of the allowable voltage limit. In the case of a contingency on the N-2 transmission lines, there were several substations that were disconnected from the electricity system, including Kuta, Mataram, Sengkol, Mantang, and Sekotong. So it is necessary to plan for additional transmission lines so that those substations dose not lose the continuity of the flow of electricity, especially at Kuta substation which is a tourist center.
