Abstract

Indonesia memiliki potensi air yang begitu besar yang dapat dimanfaatkan sebagai pembangkit listrik. Salah satu pembangkit listrik yang memanfaatkan energi air yaitu Pembangkit Listrik Tenaga Picohidro (PLTPH) yang prinsip kerjanya mengkonversi energi air menjadi energi listrik. Penelitian ini dilakukan bertujuan untuk merancang PLTPH dengan menggunakan turbin Archimedes Double Screw dan mengetahui performa dari turbin archimedes screw dan archimedes double screw pada saluran irigasi. Metode yang digunakan yaitu studi literatur dengan mengumpulkan berbagai data mengenai turbin archimedes screw pada pembangkit listrik berskala kecil untuk memudahkan dalam merancang turbin achimedes double screw.Beberapa parameter yang perlu diperhatikan sebelum merancang PLTPH dengan menggunakan Turbin Archimedes Double Screw yaitu: debit, kecepatan aliran, daya potensial air, diameter turbin, diameter poros, pitch turbin, panjang turbin, jumlah ulir, dan kapasitas generator. Setelah merencanakan desain turbin,dilakukan perakitan turbin dan pengujian pada turbin untuk mengetahui performa dari turbin archimedes double screw. Hasil pengujian Turbin Archimedes single screw didapatkan nilai daya turbin tertinggi yaitu 124,286 Watt dengan tingkat efisiensi sebesar 61,62% pada pembebanan massa 8 kg sedangkan untuk pengujian Turbin Archimedes double screw didapatkan nilai daya turbin tertinggi yaitu 272,346 Watt dengan tingkat efisiensi sebesar 67,52% pada pembebanan massa 20 kg. Pada percobaan Turbin Archimedes single screw dikopel generator menghasilkan tegangan open circuit sebesar 24,2 V dengan daya tertinggi yang dihasilkan ketika melayani beban lampu yaitu 5,72 Watt dengan beban 13 lampu 10 Watt sedangkan Turbin Archimedes double screw dikopel generator menghasilkan tegangan open circuit sebesar 23,3 V dengan daya tertinggi yang dihasilkan ketika melayani beban lampu yaitu 34,61 Watt dengan beban 13 lampu 10 Watt. Berdasarkan hasil penelitian yang dilakukan, maka dapat dilihat bahwa performa Turbin Archimedes double screw lebih baik dibandingkan Turbin Archimedes single screw jika dibandingkan dari segi efisiensi dan daya yang dihasilkan.

Abstract

The specific objective of this research is to producea system of internallightning and Eksternal lightning rod withgrounding which has been widely used in industries such aslightning protection and grounding system of substation,transmission lines and coupling wire used in high-rise buildingseither belong to government or private property. In this study,lightning rod is located outside the building structure that servesto catch or receive the bolt of lightning and the lightning deliverto the ground safely. In this study there were 5 different depths ofelectrode rod; 3 m, 5 m, 7 m, 9 m, and 12 m, moreover, 5 widevariety of electrode plate that are 1 x 1 m2, 0.75 x 0.75 m2, 0.5 x0.5 m2, 0.35 x 0.35 m2, 0.25 x 0.25 m2. For grounding electrode rod with a depth of 3 m, 5 m, 7 m, 9 m, 12 m in dry conditions grounding resistance values obtained ranged from 1.55 to 2.03 Ohm. For moist soil conditions, grounding resistance values obtained ranged from 2.21 to 2.60 Ohm. For wet soil conditions grounding resistance values obtained ranged from 1.97 to 2.34 Ohm. For grounding plate, R11 and R12 on the dry conditions grounding resistance values obtained ranged from 2.08 to 2.45 Ohm. For moist soil conditions grounding resistance values obtained ranged from 1.88 to 2.18 Ohm. For wet soil conditions grounding resistance values obtained ranged from 1.55 to 2.06 Ohm. On the external lightning rod with two added electrodes with a depth of 12 m and then connected in parallel with the electrode plate to get the smallest value of grounding resistance in accordance with the standards prescribed.

Abstract

On one hand, the particular objective of this research is to yield the software program in order to control efficiently the important aspects in electric power systems which can be implemented in industries. In the other hand, the longterm objective is to extend the curriculum, syllabi, laboratory facilities, and to improve the abilities and qualities of graduates continuously either within State Polytechnic of Ujung Pandang or outside. Method used to achieve these objectives is making, design and implementation which will be last for two years. Simulator for generation system in the first stage of the research is balanced six-phase system yielded from the circuit of 3-one phase centre-tap transformers of 220/18 V, 15 A, as the supply of low-tension 3-phase system, which feeds six one-phase transformer of 18/220 V, 20 A, whose output as another balanced 3-phase system with 220 V/phase. From balanced 6-phase system, a balanced 3-phase will simulate generator number 1 and another balanced 3-phase will simulate that of number 2. Interface which is based on Delphi program is to switch all transmission lines. The result of experiment shows that voltages in the two generator busbars experience the significant drop voltage if they work separately, that are 20.5% - 36.4% and 20.5% - 63.6% for generator number 1 and number 2 respectively, for one to three load busbars operated sequentially, which also reveals that greatest voltage drop occurs in the generator busbar with most lines supplied. Simulating the two generators working simultaneously, then voltage drops are more significant, that are 65.9% - 72.7% and 65.9% - 79.5% for generator number 1 and number 2 respectively, for one to three load busbars operated sequentially, which also proves that transformer bank as generator simulator needs to increase its current capacity.

Abstract

A 20 kV cubicle is a set of electrical equipment installed in a distribution substation as a distributor, circuit breaker, connector, controller, and protection system for the 20 kV voltage power distribution. The frequent issue in these cubicles is corona discharge on electrical equipment, which is a phenomenon occurring when the air around conductors or conductive materials becomes ionized, resulting in the release of charges that can lead to insulation failure in the equipment. The consequences are severe as it can damage the equipment inside the cubicle and cause power losses. This research analyzes the influence of humidity, temperature, sound, and light conditions inside the cubicle to identify the symptoms of corona discharge in the 20 kV cubicle and its accessories. The goal is to create a tool that can address and anticipate the issues related to corona discharge caused by the effects of humidity, temperature, sound, and light.
