Banco de pruebas experimental para esquemas de control por cambio del ángulo de paso en aerogeneradores.

The growing worldwide energy demand requires the design and construction of increasingly efficient generation systems. In satisfying this need, control schemes play an essential role. Having a system that allows experimental evaluation of their performance is key. In the case of wind energy, one possible control strategy is pitch regulation, which is used in variable pitch wind turbine systems. This paper presents the results of the design and construction of a testing bench for carrying out the experimental evaluation of control strategies for pitch regulated small wind turbines. Rotor operation and pitch regulation were ascertained through wind tunnel testing. Rotors start moving with winds of 3.5 m/s. PI and fuzzy controllers were implemented and tested.
