| description | This report proposes a new series compensated induction generator/battery supply topology which can be used to provide constant voltage and frequency at the output. This also provides minimum harmonic distortion at the output voltage.
There are two parts to this project. The first part is the hardware prototyping part and the second is the digital close loop control implementation part. The hardware prototyping of the proposed system is completed and was tested with a feed-forward loop control. Here the pulse width modulation-voltage source inverter( PWM-VSI) configuration was made to act as a capacitor by forcing the output current of the inverter to lead by ninty degrees (phase) to its output voltage. The PWM-VSI then supplies reactive power into the system.
As for the second part a detailed close loop control technique to provide good voltage and frequency control has been worked out. All major components involved in the control technique has been configured and tested. Only the Kp ,Ki and the saturation values of the Proportional Integral controllers need to be fine tuned in future work. |
