Notes

The proliferation of highly sensitive computerized equipment places increasingly more stringent demands on the quality of electric power supplied to the customer. Low power quality can cause serious problems for the affected loads, such as short lifetime, malfunctions, instabilities, interruption, and etc. The key reason for our increasingly keen interests in power quality lies in the great economic value directly associated with those disturbances. Poor power quality is normally characterized by the presence of disturbances such as harmonics distortion, capacitor switching, high impedance faults, transformer inrush currents, lightning pulses, and motor starting transients. In order to improve the quality of service, electrical utilities must provide real-time monitoring systems that are able to identify the signatures of different disturbance events and thereby providing mitigation techniques to these power quality problems that will help practicing engineers and scientists to design better energy supply systems and mitigate existing ones.


I would like to express my sincere gratitude to my guides, Dr. Trapti Jain and Dr. Amod C. Umarikar for giving me the opportunity to work on this project. Their timely guidance and invaluable suggestions were extremely helpful throughout the course of the project.

I would like to extend my gratitude to Karthik Thirumala for his help and time in the useful academic discussions I have had with him.
I am also extremely thankful to Sushmita Pal, my family and some other friends of mine for helping me with their constant support and motivation during the entire period of this project work.
