Estudo das estratégias de controle de um SCEE de pequeno porte para geração elétrica, aplicado ao carrregamento de bateria.

Abstract

The present dissertation involves aspects of the engineering of wind energy conversion systems applied to the generation of electric power for small door wind turbines for battery recharging. From the tests carried out without laboratory and tests carried out in the NERG Test Center, the modeling of the various components of the system has been carried out, aiming at the determination of parameters. The methodology of this work opts for the use of simplified models that satisfactorily describe the system. The influence of the adjustable parameters of the Weibull distribution on the SCEE is studied from the energy density expressions, trying to determine the operating range of the turbine for a wedding optimized with the velocities of the winds measured in the test center. The coupling of the turbine and the driven system is studied by analyzing the static marriage methodologies of the SCEE that aim at the analytical and graphic determination of the best transmission ratio. Open field trials are performed that evaluate the performance of the SCEE for certain conditions. USCEE study is based on the drive performed for a vertical wind turbine, type Savonius.
