Abstract:
Induction motor drive, considering its significantly indua trial applications, has great importance. Squirrel cage IM are generally controlled by varying voltage and frequency fed to the motor. For high power drive, because of use of forced commutations converters. squirrel cage IM have less application. In this case and particularly when load torque is proportional io high order of speed, wound rotor Ihl is used. In these motors speed is controlled by energy absorption from rotor and returning it to network. Return of slip energy to network improve efficiency. but Small power factor and harmonic injection rest as P predominant problem in this drive system. In Ihis paper slip energy recovery method will be studied by dvnamic modeling. To study Slip energy recovery system and effect or the method on Harmonics, power factor, lorque-sperd characteristic and overall performance oldrive, a block set is implanted in Matlab/Simulink environment.
