Dynamic Models of a Self-Excited Induction Generator Taking Iron Losses Into Account: a Comparative Study

This paper deals with the development of a dynamic model of a stand-alone self-excited induction generator (SEIG) taking into account iron losses. It is important to mention that for stable operation of the SEIG, the generator has to operate in the region of magnetic saturation. As a consequence, in any accurate analysis, iron losses must be included. This is particularly the case for small induction machines, where the magnitude of the current in the resistance representing the iron losses can not be neglected compared to that of the magnetising current. The iron losses are represented by means of inserting an equivalent loss resistance in the equivalent circuit of the SEIG. Three places are commonly used to insert the iron loss resistance; in parallel with the magnetising inductance, before the stator leakage inductance or before the stator resistance. Three models are consequently developed and are applied to a 3 kW induction generator. An experimental investigation is carried out to compare the performances of these three models in terms of accuracy and time consumption.
