Abstract

RSBM feeder is one of the feeders sourced from transformer 2 of the Amlapura Substation. This feeder is a radial type 20 kV distribution network configuration with 133 distribution transformers with a total power of 5.428 kVA and a load of 144 amperes. The lowest voltage condition in RSBM feeders has reached 18,608 kV or a voltage drop of 6.96%. To overcome the voltage drop and power loss in RSBM feeders, it is necessary to reconfigure the network. Network reconfiguration is done by planning a new feeder (Rendang feeder). Analysis of power loss and voltage drop using the help of ETAP software. Based on studies that have been done, before the network reconfiguration is obtained the percentage of voltage drop is 6,98% and the power loss is 5,68%. After being reconfigured with a new feeder plan (Rendang feeder), it showed good results, ie the percentage of voltage drop dropped to 2.09% and the power loss dropped to 3.20%. Whereas the Rendang feeder showed good results with the percentage of voltage drop of 2.78% and the power loss of 3.47%. Based on load forecasting for the next 5 years on RSBM feeders the voltage drop and power loss are still according to the standard. Whereas the Rendang feeder occurs a voltage drop and a power loss that is not up to standard in 2023, namely a voltage drop of 5.20% and a power loss of 5.07%. So that for the Rendang feeder in 2023 it is necessary to break the load or reconfigure the feeder again.

Abstract

Increasing energy demand with limited resources is an obstacle in supplying demand for electrical energy sources at this time. The solution to this problem becomes essential due to the planning of excessive energy supply, as well as planning that does not meet the energy demand will cause new problems on the side of energy production. Therefore accurate energy consumption forecasting is very important. In this study, the projected use of energy in the processing industry sector in Bali uses LEAP software using a database from 2015 to 2018. The use of fuels in the processing industry in Bali according to modeling results will continue to increase until 2050. This increase due to an increase in population resulting in increased demand for processing industry products so that the production of processing industries has increased which directly increases fuel consumption. This increase in production is also due to increased purchasing power, this is shown from the increase in per capita GRDP of Bali province which has increased until 2050. GRDP of the processing industry according to modeling results has increased until 2050 this is in accordance with the energy needs of the processing industry , where an increase in the production of the processing industry will also result in an increase in the GRDP of the processing industry

Abstract

Rugi energi terjadi jika jumlah energi yang disalurkan tidak sama dengan energi yang diterima oleh konsumen tenaga listrik. Rugi energi merupakan salah satu parameter kualitas jaringan listrik. Rugi energi yang tinggi pada jaringan dapat mengakibatkan pula rugi tegangan yang tinggi, sehingga tegangan pelayanan menjadi turun. Menurut SPLN 1, 1995 tegangan pelayanan maksimum adalah +5 % dan minimun -10 % terhadap tegangan nominal. Salah satu cara untuk menurunkan rugi energi yang dilaksanakan oleh PT PLN (Persero) adalah dengan mengganti tap connector tiap sambungan jaringan tegangan rendah dengan connector type press. Penelitian ini menganalisis besarnya rugi energi yang terjadi sebelum penggantian dan setelah penggantian connector. Hasil analisis menunjukkan bahwa dengan dilaksanakannya penggantian tap connector, maka rugi energi pada jaringan tegangan rendah yang terhubung pada transformator DS105 dapat diturunkan sebesar 63,4327 Wh atau sebesar 23,2448%. Dengan kata lain, rugi energi dapat diturunkan dari 272,8896 Wh sebelum penggatian tap connector menjadi 209,4569 Wh setelah penggantian tap connector.
