Abstract:
Reliability and cost-effectiveness are the main reasons behind the extensive use of
induction machines in industry. However, major drawback of Induction machine is that
they draw reactive power. Several techniques were adopted in past in order to improve
the performance of Induction machine. In recent years, Rectifiers and Inverters were
introduced and gained a lot of attention and helped in improving the Dynamic
performance and Power Factor of an Induction machines.
In this project, a Converter-based circuit is designed and attached with an Induction
machine in order to explore the Dynamic performance and to improve the Power Factor
of machine. A model is designed in SIMULINK and its performance is judged. Then an
experiment is conducted by implementing the same model on induction machine.
Different parameters are observed like efficiency, Power Factor and Dynamic
performance of Induction machine (which includes starting, loading, load changing,
capacitor voltage, rotor current, stator current and speed). However, simulated and
experimental results should showcase an agreement. Moreover, the above-implemented
technique is compared with previous Power Factor improvement techniques, which
were adopted in past in order to improve the performance of Induction machines.
