Harmonic and Power Factor Analysis with Reactor and Capacitor in Adjustable Speed Drive

Ac line reactor, Dc link reactors and shunt capacitors are mostly used for improving the power factor and reducing the THD level in the adjustable speed drive (ASD) and protecting the device from other power quality problem. The effectiveness of these reactors are affected by many other factors such as loading and source impedance. Under variable load conditions such factors are analyzed and performance of system also analyzed. In this paper simulation is done by inserting such factor which also suggested for future real time applications.
