Abstract:
This work deals with a novel method of magnetizing inductance investigation using field-circuit type finite element of dynamic regimes of the three-phase Self-Excited Induction Generator (SEIG) used in the isolated small wind power conversion systems. Proposed method uses normal component of the flux density in the air gap to calculate the magnetizing inductance. the value of the stator leakage inductance of the machine has calculated in this paper with reasonable accuracy using finite element method.Since the magnetizing inductance is the main factor of the voltage build-up and stabilization of the generated voltage for different conditions, so an accurate calculation of the magnetizing inductance based on the magnetizing current is crucial for a realistic representation of the voltage build-up. The results of the proposed method compared with the experimental test and theoretical value of the inductance calculated from a manufacturer's proprietary design program. Experimental approach uses a synchronous test. It can be concluded that the results of the simulation using the proposed method is much closer to the manufacturer's proprietary design program than the experimental test and it can better simulate the dynamic behavior of the machine.
