Wind potential, design and analysis of portable vertical wind turbine at PLTU rembang

The geographical position of PLTU Rembang, the Rembang Coal Steam Power Plant, which is located on the northern coast of Java, makes the area get a very large supply of sea breezes. The sea breeze can be used as an alternative energy source at the PLTU Rembang. For the target of renewable energy and environmentally friendly generation, it is planned to model a portable wind turbine for lighting lamps in the jetty area. In this study, a study of the wind potential in the jetty area was carried out. Wind data retrieval is done by using a wind speed detector. From the wind potential, a portable wind turbine design was carried out using CAD. The wind turbine selected is the savonius type with a variation of the number of blades 3. By considering the ease of making the rotor, the rotor diameter is designed with a size of 0.43 m and a height-to-diameter ratio of 1.2. The portable type was chosen for flexibility and considering the safety factor.
