Analysis and Modeling of an Electromagnetic Speed Regulator for Wind Energy Conversion Systems

Nowadays, the growing increase in energy demand worldwide intensifies the search for clean and renewable energy sources used and, among the current technologies, wind energy has been highlighted like one of the most promising. This work presents a new proposal for a wind turbine conversion system using a Frequency Electromagnetic Regulator (FER) that replace gearbox functionalities and improve mechanical transmission system performance due to the high reliability and reduction of mechanical losses and maintenance costs. Besides, FER can be useful in several transmission systems wherein mechanical output speed control is the goal. The modeling is based on the wind power extraction rules, conventional three-phase symmetrical and balanced induction machine, kinematic coupling and motion equations and its performance are validated using simulation results that employ Finite Element Method (FEM) to deal with differential equations approximations.
