Abstract

Untuk memenuhi kebutuhan energi listrik di Pulau Bali yang semakin meningkat sekitar 6 – 9 % dalam 5 tahun mendatang, pemerintah telah mengupayakan pembangunan PLTU Celukan Bawang. Proyek PLTU Celukan Bawang yang dikerjakan sejak 2013 ini telah beroperasi penuh pada bulan Agustus 2015 sebagai outlet untuk penyaluran transmisi Saluran Udara Tegangan Tinggi (SUTT) 150kV. Terkait masalah isu sosial dengan penolakan warga Desa Celukan bawang terhadap pembangunan yang melintasi rumah mereka dari SUTT, maka pihak PT.PLN (PERSERO) diminta untuk melakukan strategi untuk pengamanan penyaluran agar Sistem Bali aman saat re-route jalur SUTT. Dari hasil simulasi dengan menggunakan Tools PSSE, aliran daya listrik Bali disimulasikan dalam 3 skenario. Skenario 1 melepaskan 1 Sirkit Celukan Bawang – Kapal dan mengoperasikan Pembangkit sesuai dengan merit order, skenario 2 melepaskan 1 sirkit Celukan Bawang – Kapal dan mengoptimalkan Pembangkit di Jalur Selatan, dan skenario 3 dilakukan dengan melepas kedua sirkit Celukan Bawang – Kapal dan mengoperasikan pembangkit di jalur Selatan. Berdasarkan hasil analisis dari skenario berikut di peroleh skenario 1 memiliki kajian lebih ekonomis, andal dan bermutu dibandingkan skenario lainnya.

Abstract

Abstract - This paper introduces a redesign of Micro Hydro Power Plant (MHPP) in Banjar Dinas Mekar Sari, Panji Village, District of Sukasada, Buleleng Regency, Bali. The MHPP has been operated since 1980 by utilizing waterflow of Tukad Pasut River. Early investigation indicated that there is a reduced production capacity of the MHPP due to lack of maintenance. In addition, the initial design of the MHPP has not adopted the advanced power control systems, resulting in inefficient power production. The introduced design of the new MHPP utilizes a crossflow turbine to accommodate a waterflow rate of 1,32 m3/s and with an effective head of 16 m. The turbine mechanical energy is coupled to a generator by means of a belt coupling system, with a belt length of 3099 mm. The pulley diameter is 750 mm for the turbine side, and it is 149 mm for the generator side. The generator capacity is 185 kVA, 50 Hz, 230/400 V, 1500 rpm, and with an efficiency of 94%. The Electronic Load Controller has a capacity of 180 kW, with 6 ballast loads of 30 kW. The connection from the generator to the transformer uses the NYFGbY underground cable of 4 × 95 mm2, with a length of 69 m. The transformer is a step-up and step-down type with a capacity of 250 kVA.

Abstract

An on-grid solar power plant will distribute electric power to the grid in normal conditions. But when the supply of grid outages (islanding), on-grid solar power plant also can’t operate because the loss of the reference signal that is used as a reference for the inverter in the synchronization process. So there is potential loss of power when solar power plant can be used as a substitute source of electrical energy while PLN can’t serve consumers. In this research developed a simulation model that refers to the off grid solar power plant 500 Wp in the Department of Electrical Engineering, University of Udayana and can operate on-grid and off grid when islanding in matlab simulink. In this model made operation scenario where solar power plant operates on grid at the beginning of the simulation and after that operate off-grid (not connected to the grid and supply the local load). The simulation results show the model off grid solar power plant has been able to generate a voltage of 220 V and a frequency of 50 Hz in accordance with the solar power plant at the research site. The simulation results also show model of on grid solar power plant has been able to synchronize to the low voltage grid of PLN not loaded and loaded. On/off grid solar power plant model can operate on-grid or off-grid that corresponds to the operation scenario and produce the same output. Thus solar power plant can supply.

Abstract

Around the world the deregulation of the electricity business sector has changed from a centralized and integrated into a segmented industry based on the competence of the business people. The new form of trade with free access to transmission and distribution channels has encouraged a competitive trade between consumers and plant owners. In such environments, the transmission network is considered a key factor in the electricity market. Utilization of other companies' transmission to distribute electric power is commonly known as PBJT or Wheeling Transaction. The term PBJT in Indonesia is known as Joint Transmission Network Usage. There are several methods used to calculate transmission lease cost in this paper are used two cost allocation calculations that allow to apply to Bali electricity system that is, Postage-Stamp Rate method, MW-mile method. In this paper, we will apply the Postage Stamp Rate and MW-mile method of Wheeling Transaction in order to obtain the calculation of transmission lease cost acceptable by both parties. Keywords- Transmission, PBJT, Wheeling Transaction, Postage-Stamp Rate, MW-mile

Abstract

Lighting is one of the primary needs of humans wherever they are, because the presence of lighting will greatly help human activities and productivity. The more the number of people the need for lighting also increases. This means that it is directly proportional to electricity needs. In this study the calculation of the savings of LED lights was carried out using the Life Cycle Cost (LCC) method in BRI Regional Office buildings in Denpasar. As a result, the replacement cost for the Philips brand LED costs Rp.145,093,000.00. Energy saving obtained is equal to 11,309.49 kWh per month, so the bill savings obtained with the electricity tariff per kWH Rp.1,117.00 is Rp.12,632,700.00 every month. The operational cost of LED lights was originally Rp.132,172,421.00 will experience a gradation of inflation rate of 4.2% so that during the life time of the lamp (4 years) it will be a total of Rp.562,939,535.08. The total LED LCC is Rp.708,032,535.08 with a period of 4 (four) years, while the total existing LCC lights are Rp.628,293,771.91 with a period of 2 (two) years. The economic feasibility study using the PBP method shows results that are feasible to be accepted, but for the NPV method, the IRR and PI show results that have not been properly received. Based on calculations using the NPV method and PI, it can be seen that to be a feasible outcome, the initial cost is a maximum of Rp.108,468,555.35.

Abstract

Kondisi eksisting kelistrikan Bali hingga tahun 2013 disuplai oleh tiga pembangkit tenaga listrik dan sebuah sistem interkoneksi Jamali dengan keseluruhan daya suplai sebesar 676 MW. Berdasarkan peramalan beban sistem Bali 2013-2030 diperoleh rata-rata pertumbuhan beban 6,61%. Berdasarkan hal tersebut PT PLN (Persero) merencanakan penambahan pasokan daya listrik ke pulau Bali dengan penambahan kabel laut, suplai melalui SUTET 500 kV interkoneksi Jawa-Bali, serta pembangunan PLTU Celukan Bawang 980 MW. Dengan beroperasinya unit-unit tersebut diperlukan analisis keamanan suplai sistem kelistrikan Bali, dengan dua skenario. Skenario 1 yaitu sistem Bali hanya menerima pasokan dari PLTU Celukan Bawang pada tahun 2016 sebesar 380 MW. Skenario 2, PLTU Celukan Bawang beroperasi sebesar 380 MW tahun 2016, kemudian pada tahun 2020 dan 2022 menambah daya masing-masing 300 MW. Selain analisis keamanan suplai dilakukan juga analisis keandalan dengan beroperasinya SUTET 500 kV di Bali. Analisis keandalan SUTET 500 kV menggunakan tiga skenario. Skenario 1 SUTET beroperasi dari Paiton sampai di GITET Gilimanuk, Skenario 2 SUTET beroperasi dari PAITON sampai di GITET New Kapal, dan Skenario 3 SUTET beroperasi dari Paiton sampai di GITET Kapal. Dari hasil analisis keamanan suplai diperoleh skenario 1, pada tahun 2022 beban puncak mencapai 1304,10 MW dan pada kondisi N-1 mengalami krisis daya listrik -48,3 MW. Skenario 2, pada tahun 2028 dengan beban puncak 1862,60 MW dan pada kondisi N-1 mengalami krisis daya listrik -6,8 MW. Sedangkan analisis keandalan beroperasinya SUTET 500 kV di Bali diperoleh: Skenario 1 nilai SAIFI = 2,0 kali/km/tahun dan nilai SAIDI = ±10 menit/tahun, Skenario 2 nilai SAIFI = 3,1 kali/km/tahun dan nilai SAIDI = ±15 menit/tahun, Skenario 3 nilai SAIFI = 3,3 kali/km/tahun dan nilai SAIDI = ±17 menit/tahun.
