【 摘 要 】

The study focuses on the integration of the darrieus and savonius wind turbine to a vertical axis wind turbine for power generation. The material used for darrieus was fiber glass with three blades and diameter of 350 mm, and polyvinyl chloride (PVC) for the savonius with four blades and diameter of 100 mm. The evaluation was conducted using a controlled wind source to vary its linear wind velocity. The actual power generated was compared to the theoretical power generated to identify the efficiency of the system. With the lowest linear wind velocity of 2.63 meters per second, the actual power output of the system (combination of the darrieus and savonius power output) was 3.79 watts and the theoretical power output is 6.03 watt. This made the system to be 62.85% efficient with low wind velocity. With the highest wind velocity of 12.52 meters per second, the output of the system was 408.80 watts and the theoretical output is 650.61 watts. This made the system to be 62.83% efficient. In an overall performance of the system with varying linear wind velocity, the efficiency of the system is close to 63%.
