Rancang Bangun dan Analisis Perbandingan Efisiensi Turbin Angin Tipe Rotor Savonius dan H-Darrieus

Abstract

Wind energy is one of the potential renewable energy sources to reduce dependence on fossil fuels, but choosing the right type of wind turbine is still a challenge to optimize energy conversion. This study compares the efficiency of Savonius and H-Darrieus rotor type wind turbines under different wind speed conditions to determine the best performance in each scenario. The research was conducted using the experimental method through design, testing, and data analysis with wind speed variations from 2 m/s to 6 m/s. The test results show that at low wind speeds (2-3 m/s), the Savonius turbine is more efficient with an output voltage of 3.6 V at 2 m/s and 8.6 V at 3 m/s, while the H-Darrieus turbine only produces output voltages of 3.5 V and 5 V at the same speed. However, at higher wind speeds (5-6 m/s), the H-Darrieus turbine showed performance with an efficiency of 2.7% and a maximum torque of 88.17 Nm compared to the Savonius turbine achieved an efficiency of 0.98% and a torque of 18.9 Nm. The Savonius turbine is more suitable for low wind conditions, while the H-Darrieus turbine is more optimal for high wind speeds, so its selection must be adjusted to the environmental conditions.
