Abstract

Energi angin merupakan salah satu energi yang dimanfaatkan untuk menghasilkan energi listrik dengan menggunakan Sistem Konversi Energi Angin (SKEA) berupa turbin angin. Adapun salah satu parameter yang perlu diperhatikan dalam merancang bilah turbin angin adalah penentuan sudut pitch bilah turbin angin yang mana akan mempengaruhi performansi dari turbin angin, yaitu kecepatan sudut rotor, kecepatan angin optimal, dan koefisiensi daya. Sehingga diperlukan sistem kontrol dan pemilihan sudut pitch optimal, yaitu sudut dimana turbin memiliki koefisien daya maksimal pada jangkauan kecepatan angin. Hasil penelitian turbin angin yang dibangun diuji dengan enam variasi kecepatan angin pada 1.6 m/s, 1.7 m/s, 1.8 m/s, 1.9 m/s, 2.3 m/s dan 2.6 m/s mendapatkan daya maksimal pada sudut optimal pada range 40-60 memiliki Cp (Coefisien Power) rata-rata 0.569707 dan dapat menghasilkan daya maksimal 25.7 watt. Hasil pengembangan penerapan system kontrol PI-logika Fuzzy pada plant turbin angin dari beberapa percobaan setpoint menghasilkan rise time 107,5 detik, settling time 253 detik, maksimal overshoot 7.4%, error steady state 3.89%, dan IAE (Integral Absolute Error) 2123. ================================================================================== Wind energy is one of the energy used to generate electricity by using Wind Energy Conversion Systems (SKEA) in the form of wind turbines. One of the parameters that need to be considered in designing a wind turbine blade is the determination pitch angle of wind turbine blades which will affect the performance of the wind turbine, the rotor angular velocity, optimal wind speed, and power coefficient. Therefore, control systems and the selection of the optimal pitch angle, which is the angle of pitch in the turbine can produce maximum power coefficient in the range of wind speeds is necessary. Experimental results with six variations of wind speed at 1.6 m /s, 1.7 m/s, 1.8 m/s, 1.9 m/s, 2.3 m/s and 2.6 m /s show that optimum angles of wind turbine’s pitch are in the range of 40-60 and has a average of Cp (power coefficient) value of 0.569707 and can produce a maximum power of 25.7 watts. The results of PI-Fuzzy logic control on a wind turbine plant for several setpoints experiment show the best rise time measured at 107.5 seconds, settling time at 253 seconds, maximum overshoot of 7.4%, steady state error of 3.89%, and IAE (Integral Absolute Error) of 2123.
