Design and Development of a Laboratory-Scale Wave Power Plant Using the Oscillating Water Column System
AbstractRenewable energy is one of the strategies promoted by the government to enhance national energy resilience and reduce dependence on fossil fuels. As an archipelagic country, Indonesia has great potential in utilizing ocean energy, particularly wave energy. This study aims to design and construct a laboratory-scale wave power plant using the Oscillating Water Column (OWC) system and to analyze the electrical voltage generated by the turbine under various test conditions. The method used is an experimental laboratory approach, involving a system composed of an oscillation tank, a DC motor as the wave-generating mechanism, and a DC turbine as the generator, tested both with and without a boost converter. The artificial waves generated by the pushing mechanism produce air pressure in the chamber, which rotates the turbine to generate electrical voltage. The experimental results show that optimal performance occurs at a water height of 26 cm and a wave height of 2 cm, with a wave period of 0.502 seconds. The maximum voltage output produced by the turbine was 3 V when connected to a boost converter. These results indicate that the OWC system is capable of effectively converting wave energy into electrical energy in a laboratory-scale setting. |
