The power generation, using hydrokinetic turbine, has been significantly studied in recent
years. Such importance is due to the use of clean energy source with low environmental
impact. That kind of technology converts the kinetic energy transported by marine and fluvial
currents into mechanical energy and, consequently in electrical energy. Therefore, this work
presents a methodology for the efficient design of small horizontal axis hydrokinetic turbines
with variable rotation. The approach uses the dynamic equation of the power train, taking …
