Power quality is essential for smooth functioning of industrial process. As industries expand, utilities become more interconnected and usage of electrically equipment increases, power quality is jeopardized. The quality of power in the power system is severely affected by the presence of harmonics. This harmonics adversely effects the power system performance. Some of the effects are over heating of metal parts, noise in motors, low efficiency in motors etc. The effects produced by the harmonics are reduced by adopting some corrective measures ....etc

POWER QUALITY MEASUREMENTS PERFORMED ON
WIND FARMS IN TURKISH POWER SYSTEM
ABSTRACT
The wind farm integration may cause power quality concerns in power systems.
Integration of large scale wind farms into power systems presents some challenges
that must be addressed such as system operation and control, system stability, and
the power quality. Therefore, determining how much the power quality would be
affected by fluctuant power production and by the connection of the wind turbines
to the power system is the most important issue ....etc

Power Quality Issues in a Hybrid Power System


INTRODUCTION
Since ancient times, wind turbine technology has been
used to improve the quality of life for many people. People
have used wind turbines to pump water, mill grain,
and do many other things .
In today’s world, wind turbines are used for similar
purposes (i.e., water or oil pumping, battery charging, or
utility generation). One important aspect of wind turbine
applications, especia ....etc

POWER QUALITY ENHANCEMENT BY COMPENSATING CUSTOM POWER DEVICES
INTRODUCTION
 The term power quality refers to maintaining a sinusoidal waveform of bus voltage at rated voltage and frequency.
 Over the last 20 years the number of PQ problems are experienced in industrial and commercial sites are increased dramatically.
 The waveform of electric power at generation stage is purely sinusoidal and free from any distortions. There are many devices the distort the waveform tha ....etc

Abstract

Taking advantage of S-transform(ST), the paper proposes a new method of detecting and classifying power quality disturbances. The S-transform is unique in that it provides frequency-dependent resolution while maintaining a direct relationship with the Fourier spectrum. The features obtained from S-transform are distinct, understandable and immune to noise. According to a rule-based decision tree, eight types of single power disturbance and two types of complex p ....etc
