Abstract

BOURAS, Abdelkarim et al. Experimental investigation of an alternative wind energy generator, particularly designed. Rev.fac.ing.univ. Antioquia [online]. 2021, n.101, pp.100-107.  Epub Sep 17, 2021. ISSN 0120-6230.  https://doi.org/10.17533/udea.redin.20200802.

The growing interest in wind energy is proven by the increasing cumulative capacity of wind turbines installed around the world. This article presents the experimental study of a wind energy conversion system using a very specific alternative current generator that differs from the doubly fed induction generator (DFIG), or the permanent magnet synchronous generator (PMSG). The generator that we recommend is similar to an Electrically Excited Synchronous Generator (EESG) mounted upside-down. It is equipped with a multipolar inductor stator supplied with direct current and a ring rotor by which it distributes the alternative electrical energy produced to the utility grid. The selectivity of a relatively low direct current injected into the multipolar stator can produce the voltage desired by the user at the terminals of the generator. This wound rotor alternative generator (WRAG) operates in synchronous mode. In addition, combined with power electronic interface (PEI) converters on the rotor side, WRAG can adapt the voltage produced to the frequency of the utility grid for a range of low wind speeds, without a gearbox. An experimental validation was performed on a 3 kVA machine, it is possible claim to be an intermediate solution to the PMSG and the DFIG with greater reliability in isolated sites and agricultural farms.
