Abstract

Many of the renewable energy systems (RES) use planetary gears for the speed increase or reduction. The paper presents a 2 DOF planetary gear transmission to be used as “speed increaser” in the counter-rotating wind turbines, hydropower plants, and, also as “speed reducer”, in the tracking systems that equip the solar photovoltaic or solar thermal systems. The transmission modelling, simulation and examples of applications in the field of renewable energy systems is presented in the paper.

Keywords

Renewable energy system (RES) Planetary gear Counter-rotating
