HARMONICS AND THEIR EFECTS ON POWER SYSTEM
Seminar Flow
Why we need to study harmonics.
What are harmonics
How are they generated
What effect these harmonics have.
What are the measures to counter them.
Why study Harmonics
Presence of harmonics in the power system severely affects its operation and stability.
Everyday more and more no. of non-linear loads are being connected to the power system.
Harmonics have the potential to disrupt or outright destroy the power s ....etc

Active Filters



1. Introduction

In this chapter, we will deal with active filter circuits. Why even bother with active
filters? Answer: Audio. Most (99%) of audio devices have filters in them. They allow
you to separate out different frequency regimes. Your project this semester is to design
an audio amplifier. This chapter is organized as follows:
2. A Review of Complex Numbers and Introduction to Frequency Response: In this
section, I talk about why complex numbers, the standard form of a comp ....etc

NOVEL ACTIVE POWER FILTERS FOR HARMONICS SUPPRESSION



INTRODUCTION
CONCEPT OF HARMONICS
Harmonics can be defined as entities having a frequency in integral multiples of the fundamental frequency. This means, if we have a fundamental frequency of f Hz, the entities 2f, 3f, 4f, 5f etc. are called as harmonics. During the past decades many power electronic devices such as 6-pulse converters, variable speed motor drives, and other power electronic equipment for energy fl ....etc

Have you ever heard about cream which can actually penetrate into the skin and reduce cellulite. Yes a unique formulation has been developed which can enter the skin through its pores and reduce the cellulite that is formed beneath it.
To prove this, the test was conducted by an independent TV for current affairs. They selected a wide variety of women and then tested the unique formulation on them. To watch the video please visit http://youtubewatch?v=OFbWhRTVxso. As you can see in the video the results are quite amazing. Within just 7 days ....etc
