Abstract

Rotating electrical machines are designed at many levels and from a number of different points of view. The development of powerful computation engines in previous decades allowed for the use of numerical methods in electromagnetics. In electrical machines, the magnetic field effect the dimensions of iron parts due to magnetostriction. In this paper, Doubly Fed Induction Generator (DFIG) is modelled and analyzed using ANSOFT MAXWELL which results in distribution of magnetic flux for all the parts of the machine. The Low Voltage Ride Through (LVRT) is the cause of magnetostriction in DFIG. To capture this effect, the LVRT is created in DFIG model using MATLAB SIMULINK to predict the fault current and voltage magnitudes. The same fault current and voltage magnitudes are used for analyzing the ANSOFT MAXWELL DFIG model.
