| Abstract |
In this paper a generalized model for the optimal control of the adjustable speed slip power recovery system driving a constant load torque at varying speed is deduced. The reactive power exchanged between the machine and the two power sources is minimized subjected to the constraints that the induction machine is driven at any speed under constant load torque and the rotor current is lower than its rated value. The optimal solution of this problem is the rotor voltage space phasor defined from its rms value and its phase angle with respect to the rotor current for each operating point. The characteristics of the drive with minimal reactive power control are studied. The use of this technique leads to the improvement of the overall drive performance. |
