Abstract

This paper presents a new system for speed control in wind turbines, the “Electromagnetic Frequency Regulator” – (EFR). One of the most used devices in some topologies to perform the speed control are boxes of mechanical gears, plus a short shelf life, often represent sources of noise and defects. The EFR eliminates the use of these gearboxes, representing a technological breakthrough, making use of a machine adapted induction, where the then known stator of the machine becomes mobile, sympathetic to the turbine shaft. The aim of this study is to evaluate through simulations, efficiency in the speed control for wind variations and reference signals. Simulations showed good results, validating the proposed.
