Abstract:
Voltage sag are the major source of power quality related problems. Dynamic Voltage restorers (DVR) are used to protect sensitive loads from the effects of voltage sag on the distribution feeder. It injects voltage in series with the system voltage to compensate the sag. This paper presents a power system operation with PI controller approach. Total Harmonics Distortion (THD) is calculated for the system in absence of compensation scheme next THD is evaluated when DVR ....etc

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

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

HARMONICS REDUCTION



HARMONICS REDUCTION

The harmonics present in a dc to ac inverter are very much obvious compared to the harmonics that can be present in an ac to dc converter. This is because of the output of dc to ac inverter being ac. Thus, the filters that are used in dc to ac inverter have different designs compared to the filters used in ac to dc converters. In case of ac to dc converters, the main objective is to improve the output voltage ripple. Thus, passive filt ....etc
