“…Permasalahan utama dari turbin angin adalah kecepatan angin yang berubah-ubah setiap waktu, sehingga mempengaruhi secara signifikan terhadap kinerja turbin angin. Berdasarkan hal tersebut maka operasi turbin angin dibagi ke dalam beberapa zona guna memaksimalkan daya keluaran turbin angin dan menghindari kerusakan Semakin besar sudut pitch bilah turbin maka semakin menurun perolehan daya maksimal [2]. Melalui metode numeris dapat terlihat secara lebih terperinci pengaruh perubahan sudut picth terhadapap karakteristik turbin angin VAWT [3] dan HAWT [4].…”

Pengoperasian turbin angin terbagi atas beberapa zona operasi dengan tujuan untuk memaksimalkan kinerja turbin angin dan melindungi bilah turbin dari kerusakan saat diterpa oleh angin berkecepatan tinggi. Pembagian zona didasarkan pada besarnya kecepatan angin. Jika kecepatan angin berada diantara kecepatan nominal dan kecepatan cut out, maka turbin angin dapat dioperasikan pada nilai daya nominalnya dengan cara mengatur sudut pitch bilah turbin angin sedemikian rupa sehingga turbin angin dapat menghasilkan daya nominal. Riset ini bertujuan menganalisis hubungan antara perubahan kecepatan angin dan sudut pitch bilah turbin angin untuk mendapatkan daya nominal generator sinkron 3 fasa. Metode riset dilakukan melalui pemodelan turbin angin dengan generator sinkron 3 fasa. Turbin angin dirancang memiliki kapasitas daya mekanik 34,7 kW untuk kecepatan nominal angin 8 m/s yang dapat menghasilkan daya listrik nominal 32,68 kW, 408 volt pada kecepatan generator 1500 rpm. Hasil riset memperlihatkan perubahan kecepatan angin antara 8 m/s sampai dengan 15 m/s dapat mempertahankan kecepatan dan daya nominal generator tersebut dengan mengatur sudut pitch bilah turbin antara 00 sampai dengan 26,9270.

The wind energy is one of the renewable energy which is extracted the most amongst other resources. However, the performance still required to be improved by modifying the wind turbine blade. In this study, the modification is employed at the tip of the blade using 30° winglet. The aim of this paper is to investigate numerically the lift of force of the modified Clark Y foil in various pitch angles and predict the pitch angle at which the maximum lift is found to be maximum. There are five pitch angle variations, and they are 0°, 12°, 22°, 32°, and 42°. 3D CFD models are used using OpenFOAM 8. From the results, it can be seen that the maximum lift force was achieved at the pitch angle variation of 32° with the value of 1.245 and the maximum drag force was achieved at the pitch angle variation of 22° with the value of 1.325. While the maximum C l /C d that represents aerodynamic efficiency was achieved at the variation of 12° with the value of 2.915.
