The present paper proposes the use of an advanced algorithm based on the instantaneous powers theory for harmonics current compensation. A fast and exact computation of harmonic references is more than crucial for any active filter control strategy, especially during the transient time and frequency domains. The proposed method contains mainly two stages, the first one is based on a self-tuning filter...
This paper discusses the analysis of the effect of the permeance function harmonics induced by dynamic air-gap eccentricity in squirrel cage induction machines and explains the mechanism of generation of the harmonic components in the stator current spectrum. An analytical expressions of the motor inductance have been derived using the decomposition into Fourier series of both winding function approach...
This paper presents a new method for the voltage build-up process of an isolated-loaded dual star induction generator (DSIG) driven by a wind turbine. The machine delivers the active power to the load via two converters connected to a single capacitor on the DC side. During the voltage build-up process, the necessary stator currents references are injected by the converters; they could be calculated...
This work presents an computational tool of unbalanced voltage supply detection on-line in induction motor. A technique based on Goertzel algorithm has been used to compute the desired component frequency for real time application. The computer algorithm has been implemented in a low cost microcontroller (Arduino). Two successful methods have been used for condition monitoring of induction motors;...
