Abstract

Transformator tenaga di gardu induk berfungsi untuk mentransformasikan tenga listik ke beban. Akan tetapi tegangan yang diterima dari saluran transmisi berubah-ubah. Perubahan tegangan pada sisi terima primer transformator menyebabkan perubahan tegangan keluaran transformator pada sisi sekunder yang berdampak mengganggu peralan yang digunakan oleh konsumen dan sistem tenaga listrik itu sendiri. Untuk memperbaikan kualitas tegangan akibat perubahan tegangan di sisi primer, transformator tenaga di GI Sengkaling dilengkapi dengan on-load tap changer (OLTC). OLTC merupakan suatu peralatan pengatur tegangan untuk merubah perbandingan transformasi suatu transformator yang dalam pengoprasiannya tanpa harus memutuskan arus beban sehingga kontinuitas suatu sistem dapat terjaga. Dalam penelitian ini untuk mengetahui perbaikan yang dilakukan oleh OLTC dilakukan simulasi penentuan tegangan jangkauan kerja trafo. Simulasi Tegangan jangkauan kerja trafo yang digunakan yaitu 150 kV dan 155 kV. Dari simulasi tersebut didapatkan bahwa tegangan jangkauan kerja trafo yang digunakan OLTC untuk meningkatkan tegangan incoming pada trafo III GI sengkaling adalah 155 kV. Sedangkan dari hasil perhitungan rugi-rugi belitan trafo didapatkan bahawa setelah dilakukan tapping rugi-rugi belitan semakin kecil dibandingkan dengan sebelum dilakukan tapping. Hal ini dikarenakan dengan menaikkan tegangan menggunakan OLTC maka arus yang mengalir pada belitan akan berkurang, sehingga rugi belitan trafo juga akan semakin kecil nilainya. Kata kunci : Transformator , On-Load Tap Changer,  Kualitas Tegangan, Rugi Belitan TrafoThe power of transformator at the substation is used to transform electrucity into the load. The voltage change on the receiving side of the primary transformator causes a change in the transformator output voltage on the secondary side which affects the qeuipment used by the consumer and the electric power system itself. To improve the quality of billing due to voltage changes on the primary side, the power transformer on the Sengkaling substation is equipped with an on-load tap changer (OLTC). OLTC is a voltage regulating equipment to change the transformation ratio of a transformer that operates without having to decide the load curent so that the continuity of system flow can be maintained. In this study to find out the improvements made by OLTC, a simulation of the voltage of the transformer working range is carried out. The voltage simulation of the working range of the transformer used is 150 kV and 155 kV. From the simulation it was found that the transformer working range voltage used by OLTC to increase the incoming voltage on the GI sengkaling III transformer was 155 kV. Whereas from the calculation of the transformer entanglement losses, it is found that after the tapping of the losses, the entanglement is smaller than before tapping. This is because by increasing the voltage using OLTC, the current flowing in the winding will decrease, so that the loss of the transformer entanglement will also decrease in value.Keywords: Transformer, On-Load Tap Changer, Voltage quality,  Copper loss of transformer

Abstract

Jaringan transmisi saat ini sudah menggunakan konfigurasi single Busbar dan double Busbar. Untuk konfigurasi pada GI Banyuwangi tidak semua penghantar dalam sistem tersebut sudah dalam konfigurasi double Busbar. Padahal dengan konfigurasi double Busbar menjadikan sistem tersebut lebih handal dan memiliki jatuh tegangan yang lebih rendah. Dengan laju pertumbuhan beban yang cukup tinggi khususnya di daerah Situbondo. Untuk menghindari adanya overload atau overcurrent ketika ada gangguan pada penghantar Banyuwangi-Situbondo yang dalam konfigurasi single Busbar, perlu adanya perubahan konfigurasi ke double Busbar. Hasil analisis load flow menggunakan ETAP dengan metode Newton Rhapson menunjukan bahwa beban yang melewati penghantar bus Banyuwangi mencapai 80 % dari beban maksimal. Ketika konfigurasi sistem dirubah dari single Busbar ke double Busbar, maka beban yang melewati penghantar bus Banyuwangi dan bus situbondo hanya 63.4%. Untuk bus Banyuwangi pada konfigurasi single circuit tegangan jatuhnya 21% dari tegangan nominalnya sedangkan double Busbar tegangan jatuhnya yaitu 14% dari tegangan nominalnya. Dari hasil analisis rugi-rugi daya menunjukkan total keseluruhan rugi-rugi daya untuk konfigurasi single Busbar sebesar 62.282 MW dan 191.619 MVAR untuk konfigurasi double circuit 44.038 MW dan 137.304 MVAR.

Abstract

In order to meet the electricity demand, we need to build a reliable distribution system. However, studies found that providing a service without interruption is challenging, especially avoiding voltage drop interruption remains a difficult task. Although voltage drop interruption is ineluctable, the distribution system usually can tolerate it at a certain level or threshold. Based on the regulation standard by the Ministry of Energy and Mineral Resources of Indonesia in 2009, the safe thresholds are between -10% to +5% of the standard value. As a part of the maintenance procedure, an engineer must ensure that an electrical power distribution system follows those rules to avoid voltage drop interruptions. This study observed the power flow of four connected feeders (Buluagung, Glagah Sari, Tutur, and Kayoman) at the Sukorejo main substation. The electrical power flow of each feeder fluctuated as follows: for Buluagung, the maximum voltage drop was 4.85%, Glagah Sari was 6.65%, Tutur was 2.59%, and Kayoman was 18.89%. Kayoman had te highest voltage drop, and the value passed the defined standard from the Ministry. Thus, this study proposed a framework to reduce the voltage drop value in Kayoman by adding a capacitor bank by analyzing the loss sensitivity along with the norm method. This study performed eight simulations and simulation number four, with additional capacitor installation on buses 8, 9, 12, and 16, giving the optimal result as the voltage drop value reduced to 8.71% for Kayoman. The real and reactive power losses were 934.43 kW and 1,303.54kVAR, respectively.Keywords: distribution system, loss-sensitivity analysis, reactive power difference, voltage drop

Abstract

In the Belanda feeder the Bukit Kapur sub feeder has a total channel length of 96,777 kms and PT. Harap Panjang has quite a lot of inductive loads, so the use of electrical energy consumed by PT. Harap Panjang on the Belanda feeder is getting bigger. So drop voltage and power losses often occur in the Belanda feeder the Bukit Kapur sub feeder. Therefore, improvements were made using a capacitor bank through the ETAP 16.0 software. The results of the first analysis showed that the drop voltage on the Belanda feeder the Bukit Kapur sub feeder was 11.58% and the power loss was 232.2 kW and 263.2 kVAR. The improvement of the drop voltage and power loss of the Bukit Kapur Belanda feeder was carried out by compensating for reactive power injection using 6 units of capacitor banks with different capacities through OCP (Optimal Capacitor Placement) analysis. The result of improving the drop voltage and power losss on the Belanda feeder, the Bukit Kapur sub feeder after being given a capacitor bank, decreased to 4.37% and the power loss decreased to 176.7 kW and 190.7 kVAR.Keywords: Drop voltage, power loss, capacitor bank, Optimal Capacitor Placement (OCP)

Abstract

Solar Energy System is a renewable energy that convert sun irradiation into electrical energy through photovoltaic cell. Solar Energy System is divided into 2 types, on-grid system and offgrid system. On-grid solar energy is a system which connected to the grid. Energy Management System (EMS) is implemented in the attempt to maximize the reduction of cost for electricity. EMS implemented is by transmitting electrical energy from battery at peak load time. Solar energy with this EMS (scheme 1) will be compared with solar energy when; all energy produced by solar cell is transmitted to user load (scheme 2), all energy produced by solar cell will be exported to the grid (scheme 3), and energy produced will goes to load, if there is excess energy, it will be imported to the grid (scheme 4). The efficiency difference caused by battery don’t drastically effect the economical factor because the efficiency difference is 0,63%. Scheme 1has the highest investment cost, net profit, and COE, but since its investment cost and maintenance cost is high, scheme 1 is not worth to implement. Based on NPV, scheme 1 is the only scheme that is worth to i
