Abstract
Vertical Axis Hydrokinetic Turbine Straight Blade Cascaded (VAHT-SBC) merupakan energi hidrokinetik yang potensial untuk dimanfaatkan. Pada penelitian ini telah dilakukan ekperimen pontensi turbin dan sistem konversi hidrokinetik untuk mendapatkan sistem integrasi turbin dan generator serta konversi daya. Variasi kecepatan yang digunakan untuk menguji turbin dan sistem integrasi adalah 0.74 m/s, 0.82 m/s, dan 0.92 m/s. Didapatkan hasil performansi terbesar turbin berada pada kecepatan 0.92 m/s dengan daya turbin 174.058 watt. Sedangkan nilai efisiensi turbin pada setiap lokasi berturut 37.9, 30, 22.25. Pada sistem konversi daya eksperimen yang dilakukan adalah perubahan rpm yang diberikan serta variasi pembebanan. Hasil ekperimen menunjukkan semakin tinggi rpm maka generator dan rectifier tiga fasa akan mengalami kenaikan tegangan serta frekuensi. variasi nilai rpm pada generator adalah 493, 395, 341, 316, dan 227. Pemberian beban akan menurunkan kinerja generator yang mengakibatkan turunnya tegangan. Tegangan yang turun terjadi pada semua komponen sistem konversi daya. Inverter sendiri telah mencapai acuan yang telah ditentukan karena berada pada kisaran 230Vac. Dari hasil tersebut pengujian sistem integrasi dilakukan dengan turbin, generator dan konversi daya dengan menggunakan transmissi mekanik. Pada sistem integrasi didapatkan nilai yang linear terhadap eksperimen sistem konversi daya baik segi tegangan maupun frekuensi. Hasil eksperimen menunjukkan daya listrik terbesar yang mampu dihasilkan oleh VAHT-SBC sebesar 50 watt dengan kecepatan inlet 0.82 m/s dan 0.92 m/s

Vertical Cascaded Axis Hydrokinetic Turbine Straight Blade (VAHT-SBC) is a potential hydrokinetic energy to be utilized. In this study, turbine potential experiments and hydrokinetic conversion systems have been carried out to obtain a turbine and generator integration system and power conversion. Speed variations used to test turbines and system integration are 0.74 m/s, 0.82 m/s, and 0.92 m/s. The highest performance results of the turbine are obtained at a speed of 0.92 m/s with a turbine power of 174,058 watts. While the value of turbine efficiency in each location successively 37.9, 30, 22.25. In the experimental power conversion system carried out is the change in rpm given and variations in loading. The experimental results show that the higher the rpm, the three-phase generators and rectifiers will increase voltage and frequency. variations in the value of rpm on generators are 493, 395, 341, 316, and 227. Giving the load will reduce the performance of the generator which results in a decrease in voltage. The drop voltage occurs in all components of the power conversion system. The inverter itself has reached a predetermined reference because it is in the 230Vac range. From these results, integration system testing is carried out with turbines, generators and power conversions using mechanical transmission. The integration system gets a linear value for power conversion system experiments both in terms of voltage and frequency. The experimental results show that the largest electrical power capable of being produced by VAHT-SBC is 50 watts with inlet speeds of 0.82 m/s and 0.92 m/s.
