The soaring demand for energy and the occurrence of climate change is a serious issue throughout the world, this is a challenge for the energy production sector to decarbonize immediately by looking for an alternative source to maintain environmental sustainability as a means of mitigating climate change. Based on data from the Research and Development Agency (P3GL) of the Ministry of Energy and Mineral Resources in 2017, the annual square of the average tidal speed in the Lombok Strait is around 1.8 m/s with current speeds ranging from −2.2 to 2.5 m/s, so a suitable ocean current turbine is needed to extract power from this huge potential. In this study the turbine used was a Vertical Axis Tidal Turbine Darrieus H-Rotor type with a swept area of 2 × 332 m2. By comparing the results between NACA 0018 and NACA 634,021, the optimal results are obtained in the 3-blade configuration. Based on calculations and simulations, it is known that the power generated reaches 2 × 818.10 kW with a rotor rotation of 10.58 rpm.

摘要

The soaring demand for energy and the occurrence of climate change is a serious issue throughout the world, this is a challenge for the energy production sector to decarbonize immediately by looking for an alternative source to maintain environmental sustainability as a means of mitigating climate change. Based on data from the Research and Development Agency (P3GL) of the Ministry of Energy and Mineral Resources in 2017, the annual square of the average tidal speed in the Lombok Strait is around 1.8 m/s with current speeds ranging from −2.2 to 2.5 m/s, so a suitable ocean current turbine is needed to extract power from this huge potential. In this study the turbine used was a Vertical Axis Tidal Turbine Darrieus H-Rotor type with a swept area of 2 × 332 m2. By comparing the results between NACA 0018 and NACA 634,021, the optimal results are obtained in the 3-blade configuration. Based on calculations and simulations, it is known that the power generated reaches 2 × 818.10 kW with a rotor rotation of 10.58 rpm.
