Indonesia has an abundance of energy resources. Despite Indonesia’s 154.9 GW of wind energy potential, just 0.1% of wind power plants are operational. Wind energy is viewed as a solution for reducing pollution and carbon emissions and an alternative to fossil fuels. Wind energy utilization will be consistent with the sustainable development goals (SDGs) for clean energy availability. Maximizing the potential of renewable energy through wind turbine design and infrastructure is vital. The Savonius wind turbine study is a follow-up to an existing problem. Savonius has the advantage of operating at low speeds, and its performance can be improved through changes in its geometry design. Geometry factors in Savonius influence the performance value. The goal of this study was to create a Savonius multi-stage wind turbine design by studying several geometric elements such as stage ratio (SR), number of stages (NOS), and phase shift angle (PSA). This research is urgent because it contributes to reaching the SDGS for clean and cheap energy. Variations are determined using the Taguchi approach and the L4 orthogonal array design. The PSA has two levels: 45° and 90°. SR has two levels: 1:1 and 2:1, while the NOS has two levels: two-stage and three-stage. The results reveal the most significant variation on Savonius rotors with SR 1:1 and PSA 45°. Cpmax is 0.192, and research indicates that SR, NOS, and PSA all impact the Savonius rotor’s performance.

摘要

Indonesia has an abundance of energy resources. Despite Indonesia’s 154.9 GW of wind energy potential, just 0.1% of wind power plants are operational. Wind energy is viewed as a solution for reducing pollution and carbon emissions and an alternative to fossil fuels. Wind energy utilization will be consistent with the sustainable development goals (SDGs) for clean energy availability. Maximizing the potential of renewable energy through wind turbine design and infrastructure is vital. The Savonius wind turbine study is a follow-up to an existing problem. Savonius has the advantage of operating at low speeds, and its performance can be improved through changes in its geometry design. Geometry factors in Savonius influence the performance value. The goal of this study was to create a Savonius multi-stage wind turbine design by studying several geometric elements such as stage ratio (SR), number of stages (NOS), and phase shift angle (PSA). This research is urgent because it contributes to reaching the SDGS for clean and cheap energy. Variations are determined using the Taguchi approach and the L4 orthogonal array design. The PSA has two levels: 45° and 90°. SR has two levels: 1:1 and 2:1, while the NOS has two levels: two-stage and three-stage. The results reveal the most significant variation on Savonius rotors with SR 1:1 and PSA 45°. Cpmax is 0.192, and research indicates that SR, NOS, and PSA all impact the Savonius rotor’s performance.
