Equivalent Circuit Parameter Estimation of Induction Motor Using Parasitism Predation Algorithm

the electromechanical industries rely heavily on AC induction or asynchronous motors. However, choosing a suitable engine for specific drive applications is an uncompromising task. The use of an equivalent T-circuit for this purpose is one of the most universally accepted and effective methods. The estimation of the equivalent circuit parameter must be done relatively quickly and accurately. This paper used a Parasitism-Predation algorithm (PPA) as a new approach techniques method for calculating the equivalent circuit parameters of two induction motors. The variance between computed data and manufacturer data (objective functions) is reduced to a minimum which has been considered in the torque (starting torque, maximum torque and full load torque) and full load power factor. The results referred to that the PPA method is superior because it has a less deviation than the results obtained with other recent techniques.
