Efficient optimization techniques for parameter estimation in three phase induction machine [articol]

Abstract

Prediction of a three phase induction motor’s characteristics from its equivalent circuit is very familiar and widely used methodology. Computation of equivalent circuit parameter is usually done by no-load and blocked rotor test. The results obtained from the test may not give accurate values of the parameter and it has a wide variation in the operating condition. The obtained values were not precise and effective when analyzing the machine under various operating condition so we are urge to implement any other methodologies which makes the estimation of parameter precise. In this paper two optimization techniques i.e., Artificial Bee Colony Algorithm (ABC), Fireworks Algorithm (FWA), are applied for parametric estimation. The obtained results are compared with the actual values supplied by the manufacturer.
