ABSTRACT

Power quality has become an increasing concern to customers, utility providers and manufacturers for
the last few years.
The increased concern of power quality has resulted in measuring power quality variations and
characteristic disturbances for different industrial categories. The devices and equipments used in industry
include microprocessor-based controls and electric devices that are sensitive to many types of electrical
disturbances besides to actual interruptions.
Power quality disturbances are usually caused by load switching, system faults, motor starting, load
variations, nonlinear loads, and intermittent loads and arc furnaces. These cause many electrical disturbances
like swell, sag, harmonic distortions, interruptions, flicker and transient voltages.
There have been considerable changes in today's power systems in recent years, as emergence of
privation and deregulation in power industries. The goal of deregulation is to provide the customer with
reduced costs. The global competition between utilities leads to utility cost-cutting, downsizing and reducing
maintenance on both transmission and distribution systems.
This survey introduces the terminology and various issues related to ‘power quality’. After an
introduction of the different terminology, important power quality disturbances are discussed in detail. For each
of these disturbances, characterization, origin, mitigation, and their standards are discussed. Power quality
monitoring is mentioned. The concept of custom power is highlighted. Finally two new power quality
application devices, which are FRIENDS and Distribution Generator are given in detail
