Three phase induction motor operation and control with intelligent techniques

Abstract

Electric motors which are predominately of the three phase induction motor squirrel cage type consume about 60 of electrical energy generated in industrialized countries Induction motor have long life span and rugged in structure such that the requirement and maintenance cost is the least In industrial environment an induction motor needs starting first and variable speed operation next It is also recommended to have energy efficient operation during light load conditions In the present work attempts have been made to design and develop soft starter for induction motor variable voltage variable speed operation and efficiency enhancement operation during part load conditions Towards these objectives a few biological inspired optimization algorithms have been employed and many of them are successfully implemented on a laboratory model newline
