Abstract

Konsumsi energi listrik di Indonesia semakin lama semakin meningkat. Meningkatnya permintaan energi listrik perlu diseimbangkan dengan peningkatan sumber penghasil energi listrik tersebut. Sumber energi listrik bermacam-macam seperti tenaga air, uap, angina, diesel, batu bara, dll. Pada saat ini pemerintah menargetkan mulai 2020 penambahan pembangkit listrik baru berasal dari energi terbarukan seperti energi hidro. Potensi tenaga hidro di Indonesia sangat besar dan masih kurang dalam pemanfaatannya. Pembangkit listrik tenaga hidro memanfaatkan energi kinetik air (arus air) menjadi energi mekanik (dengan turbin) dan energi mekanik menjadi energi listrik (dengan generator). Debit air menjadi parameter yang sangat berpengaruh terhadap besarnya energi listrik yang dapat dihasilkan oleh pembangkit listrik tenaga hidro. Penulis mengambil penelitian pada kanal terbuka outlet kondensor Pembangkit Listrik Jawa-Bali (PJB) pada unit Paiton. Penelitian dilakukan pada kanal dengan panjang 260 meter dan 380 meter dengan aliran air laminer. Untuk mengetahui besarnya jarak pemasangan susunan array turbin dilakukan simulasi fluida dengan variasi kecepatan arus 1,8 m/s, 2m/s , dan 2,5 m/s. Jarak pemasangan susunan array turbin yang dapat membangkitkan daya terbesar yaitu 25 meter dengan total daya yang dibangkitkan 106,631 kW. Selanjutnya daya listrik tersebut didistribusikan ke beban untuk mendapat besarnya panjang kabel yang dapat dipasang sebelum mengalami tegangan jatuh yang ditentukan oleh IEC yaitu sebesar 5%. Beban 200 watt maksimal kabel 1061, beban 400 watt maksimal kabel 530, beban 600 watt maksimal kabel 353 meter, beban 800 watt maksimal kabel 261 meter, dan beban 1000 watt maksimal kabel 212 meter.

The consumption of electrical energi in Indonesia is increasing over time. The increasing demand for electrical energi needs to be balanced with the increase in sources of electrical energi. There are various sources of electrical energi such as hidropower, steam, wind, diesel, coal, etc. At this time the government is targeting that starting in 2020 the addition of new power plants from renewable energi such as hidro energi. The potential of hidro power in Indonesia is very large and its utilization is still lacking. Hidro power plants utilize the kinetik energi of water (water flow) into mechanical energi (with a turbine) and mechanical energi into electrical energi (with a generator). Water discharge is a parameter that greatly influences the amount of electrical energi that can be generated by hidroelectric power plants. The author took research on the open channel condenser outlet of the Java-Bali Power Plant (PJB) in the Paiton unit. The research was conducted on canals with a length of 260 meters and 380 meters with laminar water flow. To determine the magnitude of the installation distance of the turbine array arrangement, fluid simulations were carried out with variations in current velocity of 1.8 m/s, 2m/s, and 2.5 m/s. The installation distance of the turbine array arrangement that can generate the largest power is 25 meters with a total generated power of 106.631 kW. Furthermore, the electrical power is distributed to the load to get the length of the kabel that can be installed before experiencing a voltage drop determined by the IEC, which is 5%. Maximum load of 200 watts of 1061 kabel, maximum load of 400 watts of 530 kabel, maximum load of 600 watts of 353 meters kabel, maximum load of 800 watts with 261 meters of kabel, and 1000 watts maximum load of 212 meters of kabel
