Power Factor Correction Using 8051

Secondly I would also like to thank my parents, friends and family who helped me a lot in finalizing this project within the limited time frame.

We find this to be an exciting project with significant potential and wish to express our thanks to

I take this opportunity to express my sincere thanks and deep gratitude to all those people who extended their whole hearted co-operation and have helped me in completing this project successfully.

With the advent of modern controls theory and in the semiconductor technology, the use of high sophisticated technologies, advance digital controllers and embedded systems which include microprocessors, DSPs (digital signal processors), ASICs (application-specific integrated circuits), and FPGAs (field-programmable gate arrays).in the area of AC power control have become global challenges nowadays[1]. Recently FPGAs have become a good alternative answer and have been generally accepted as a tool for the controller`s platform in high performance embedded control system[2]. This device completely give inventors the ad-liberty to use their design customs

Abstract—This assignment is based on the CIGRE HVDC benchmark system and deals with understanding and simulating this system in PSCAD/EMTDC. The focus is on the rectifier station of the CIGRE system which has been idealized and simulated in PSCAD. The AC-side real and reactive power and DC-side power corresponding to the firing angle from 0 to 180 degrees has been calculated and plotted. Furthermore, the power balance between the AC and DC-side of the converter has been explained. Index Terms— Converter, EMTDC, HVDC, PSCAD, Real power,

A project without adequate direction is like a ship without its navigator. A successful story is incomplete without paying tributes to those who inspired it. From the bottom of my heart, I would like to acknowledge all those people who guided me for preparing this report, which was a great learning process for me.

Dr. Hemant. A. Patil who has been the guiding force behind this project. I want to thank him for giving me the opportunity to work under him. I consider it my good fortune to have got an opportunity to work with such a wonderful person. Without his experience and insights it would have been very difficult for quality work. I am deeply indebted to my guide Prof. Vrushank Shah for his constant motivation. I am also thankful to the authors whose works I have consulted and quoted in this work. My affectionate thanks are due to my family and my seniors at DA-IICT who made me able to do such work.

We would like to express our deep sense of gratitude towards some important people who have given their precious time towards the completion of our project.

SINCERELY I ACKNOWLEDGE MY DEEP SENSE OF GRATITUDE TO MR. SANJEEV THAKUR (ASSISTANT PROFESSOR) FOR HIS CONSTANT ENCOURAGEMENT, HELP AND VALUABLE SUGGESTIONS.

It is indeed a golden opportunity for us to present this report and indeed a matter of esteem honor itself.

| ACKNOWLEDGEMENTAt the Outset let me express my sincere thanks to IILM who provided me this golden opportunity of undergoing in project.It is always a difficult task to acknowledge all those who have been a tremendous help in an academic project of this nature and magnitude. The successful completion of the project is accredited by those people who made it possible.Nevertheless, I would like to extend my sincere gratitude towards the people who have devoted their time and ideas and played an individual part in the making of this project. It is indeed a great pleasure and

Special thanks to our HOD C.D. Kotawal for opening up a new way of seeing things and doing projects. With his unflinching directions and clear mind he illuminated us.

Finally, I would like to thank every committee member for guiding me in the project.

I would not forget to remember Prof. Suresh Pattanayak, Prof. Rupesh Kr. Tiwari and all faculty members for their unlisted encouragement and more over for their timely support and guidance till the completion of our project work. I heartily thank our internal project guide, Dr.R.S.Mohan, Dean , Department of Management, for his guidance and suggestions during this project work. I am extremely thankful to all those persons who have positively helped me and customers who respond my questionnaire, around whom the whole project cycle revolves.
