Detección de Fallas en Un DFIG Empleando el Método del Elemento Finito (I)

Resumen: Este trabajo aborda la detección de fallas de cortocircuito entre espiras del estator de un generador de inducción doblemente alimentado (DFIG, por sus siglas en inglés) utilizado para aplicaciones de aerogeneración. El modelo de un DFIG de 3.5 kW se simuló a través del método del elemento finito (MEF) en estado normal y con falla. Se analizaron las corrientes de estator en estado estable dadas por el modelo para el caso sin falla. A continuación el modelo se modificó para reproducir un segundo estado con falla de cortocircuito entre espiras, para el que igualmente se analizaron las corrientes del estator. Para la detección de fallas se utilizaron las Transformada Rápida de Fourier (FFT, por sus siglas en inglés) y Transformada Discreta Wavelet (DWT, por sus siglas en inglés) aplicadas al vector de Park de las corrientes del estator.
