| Abstract |
Variable speed and constant frequency (VSCF) generators are widely used in industry (e.g. embedded applications and renewable energy systems). Doubly-fed induction generators (DFIG) allows a such operation. Moreover, this kind of machines can be driven by a low power converter in comparison to the power provided to the grid. On isolated grid, a efficient controller is needed in order to maintain quasi-sinusoidal voltages with an important amount of nonlinear load. The aim of this paper is to present a new design methodology based on the inversion of the dynamical model of the system. It also uses an original representation of the system called dynamical equivalent circuit. Thus, a hierarchical controller is designed and validated by simulation. |
