Wind Turbine-Driven Self-Excited Induction Generator: A Novel Dynamic Model Including Stray Load and Iron Losses
Abstract
In this paper, a novel dynamic model of a self- excited induction generator (SEIG) is presented. In the proposed model, the fundamental stray load and iron losses are accounted for in a way that preserves the order of the conventional induction machine (IM) model. The corresponding equivalent resistances are determined from the standard tests. The SEIG has been considered as part of a wind conversion system. On the simulation level, the proposed model’s performance has been compared to that of the conventional model. In addition, it has been experimentally validated by using two IMs of different efficiency class, both rated 1.5 kW.
