Desenvolvimento de um Protótipo de Sistema de Geração Eólica Utilizando DFIG e Estudo de Análises Transitórias

The main advantage of using the Doubly-fed Induction Generator - DFIG, in wind power generation systems with variable speed, is that electronics used correspond only to a fraction generator’s nominal power, considering slip it processed by static converter connected rotor circuit. This paper covers details from steps mathematical modeling converters and design controllers, characterization prototype commissioned carry out study. Experimental results obtained 10kW DFIG are shown, transient analyzes under different conditions preceding stator connection electrical grid discussed validate effectiveness control strategies used. Such involve parallelism differences between voltage amplitudes stator, speed synchronous one.
