On the Emulation of an Isolated Wind Energy Conversion System: Experimental Results

摘要

This paper presents the emulation of an isolated wind energy conversion system, which is composed by a doubly-fed induction generator, a back-to-back converter connected to its rotor, a LC filter to minimize the harmonic pollution in the generated voltage and an isolated three-phase load. In first instance, the test bench is described and its operational capabilities are introduced. Afterwards, the control system design is presented. Next, some associated experimental results are shown as well. A special mention must be made to an experimental study which considers the possibility of using the self-excitation of the doubly fed induction generator to achieve the black-start of the isolated wind energy conversion system.
