Harmonic Reduction in Power System Seminar Report

Abstract

The main aim of this seminar report is to explain the effects of Harmonics in the Power System and steps to reduce the effects of Harmonics. This seminar report will also explain how Harmonic distortion is one of the most important problems associated with power quality and creates several disturbances to the Power System.  It includes the Harmonic reduction techniques to improve the power quality and it also includes the simulation for the same. 
In an inverter, DC voltage is converted into an AC output. During this transformation from DC to AC, harmonics affect the power quality a lot.  How harmonic reduction will improve the power quality is explained in detail.The principle of this seminar report is to know the effects of harmonics in a power system and to minimise the effects of the power system harmonics.This distortion will result in low power quality and improved disturbances in power system. So this harmonic technique is used to improve the power quality. This improvement includes the simulation also.The inverter is used to transform a DC into AC, during this transformation; the harmonics will reduce the power quality a lot. The increase in power quality using a technique is explained in detail in this seminar report.

Introduction

The term harmonics referred to Power quality in an ideal world would mean how pure the voltage is, how pure the current waveform is in its sinusoidal form.  Power quality is very important to commercial and industrial power system designs.  Ideally, the electrical supply should be a perfect sinusoidal waveform without any kind of distortion.  If the current or voltage waveforms are distorted from its ideal form it will be termed as harmonic distortion.  This harmonic distortion could result because of many reasons.  In today’s world, prime importance is given by the engineers to derive a method to reduce the harmonic distortion.  Harmonic distortion was very less in the past when the designs of power systems were very simple and conservative.  But, nowadays with the use of complex designs in the industry harmonic distortion has increased as well.  
This seminar report explains the effects of Harmonics in the Power System and steps to reduce the effects of Harmonics. This seminar report will also explain how Harmonic distortion is one of the most important problems associated with power quality and creates several disturbances to the Power System.  It includes the Harmonic reduction techniques to improve the power quality and it will also include the simulation for the same. This seminar report also explains different types of inverters that are used in the Power System.  During the transformation from DC to AC, harmonics affect the power quality a lot.  How harmonic reduction will improve the power quality will be explained in detail.
