Perbaikan Kualitas Tegangan Distribusi 20 kV di Gardu Hubung Lemito Melalui Studi Aliran Daya
Penurunan tegangan maksimum pada Sistem Distribusi Tenaga Listrik telah ditetapkan yakni tidak lebih dari 10% terhadap tegangan nominal. Penelitian ini dilakukan dalam rangka memperbaiki kualitas tegangan Sistem Distribusi yang dipasok dari Gardu Induk (GI) Marisa. Salah satu Gardu Hubung (GH) di sistem distribusi Marisa ini yakni GH Lemito memilki turun tegangan sampai 19.21%. Penurunan tegangan ini diakibatkan oleh GH Lemito yang suplai dari ujung penyulang LM.03 dalam pengoperasiannya melayani beban yang cukup besar, di samping itu juga penghantar utama yang menghubungkan GI Marisa ke GH Marisa masih memakai penghantar berdimensi yang lebih kecil dibandingkan dengan penghantar di percabangan dan tentunya ini menyalahi prinsip-prinsip konfigurasi pada sistem distribusi tenaga listrik tipe radial. Simulasi aliran daya dengan ETAP 12.6 digunakan dalam menyelesaikan masalah pada penelitian ini. Simulasi dilakukan dalam 4 skenario yakni 3 skenario berupa pelimpahan beban dan 1 skenario up rating penghantar. Berdasarkan hasil simulasi didapatkan bahwa skenario 3 dari alternatif solusi pelimpahan beban adalah skenario yang paling mendekati standar SPLN 1:1995 yaitu 17.8 kV dengan persentase turun tegangan sebesar -10.8%. Oleh karena persentase turun tegangan masih di atas 10% maka skenario 3 pelimpahan beban masih perlu ditambahkan kapasitor bank sebesar 2.75 MVAr. Penambahan kapasitor bank pada skenario 3 pelimpahan beban dari hasil simulasi aliran daya dapat meningkatkan tegangan di GH Lemito menjadi 20.10 kV atau naik sebesar 0.52%.The maximum voltage drop in the Electric Power Distribution System has been set, which is no more than 10% of the nominal voltage. This research was conducted to improve the quality of the distribution system voltage supplied from the Marisa Substation. One of the substations (GH) in the Marisa distribution system, GH Lemito, has a voltage drop of up to 19.21%. This voltage drop is caused by GH Lemito which supplies from the end of the LM.03 feeder in its operation serving a relatively large load, in addition, the principal conductor connecting GI Marisa to GH Marisa still uses a conductor with smaller dimensions compared to the conductor at the branch and of course, This violates the principles of configuration in a radial type electric power distribution system. Power flow simulation with ETAP 12.6 is used to solve the problem in this research. The simulation is carried out in 4 scenarios, namely 3 scenarios in the form of load transfer and 1 scenario of up rating conductor. Based on the simulation results, it is found that scenario 3 of the alternative load transfer solution is the scenario closest to the 1:1995 SPLN standard, which is 17.8 kV with a voltage drop percentage of -10.8%. Because the percentage drop in voltage is still above 10%, in scenario 3, it is necessary to add a capacitor bank of 2.75 MVAr. Adding a capacitor bank in scenario 3 of the load transfer from the power flow simulation results can increase the voltage at GH Lemito to 20.10 kV or an increase of 0.52%.
