Discuss power quality in electrical power system.

Write a 6 pages paper on power quality in electrical power system. The consequences of improper power may result in causing the electrical device to fail prematurely or not operate at all. Power quality is actually the quality of the voltage rather than the quality of power or electric current (Kazibwe and Sendaula, 1993). Power quality is actually the quality of the voltage rather than the quality of power or electric current (Kazibwe and Sendaula, 1993).

Power quality components mainly include line reactors, DV/dt reactors and filters, sine wave filters, harmonic filters, and regen reactors and filters. A line reactor is an electronic component and is generally wired between a power source and the load. Its function is to oppose sudden and rapid changes in electric current. It has the most uses for the three-phase electric power and they are usually installed in motor-driven equipment in order to limit the starting current (Fuchs and Masoum, 2008).

DV / DT is defined as the capacity of capacitors to withstand high currents. Dv / DT Filter is designed to reduce dv/dt and peak voltages to motors fed from a wide variety of inverters. The suitability of this filter is for a specific application therefore it must be determined by the customer before use. Sine Wave Filters are basically designed for converting the output voltage waveforms that are produced by a wide variety of inverters into a low distortion sine wave for a drive, power conversion applications, and various other applications (Dixit and Yadav, 2010).

Harmonic filters are used to eliminate harmonic waves and are also used for the production of necessary reactive power. The equipment is also used to eliminate spurious signals in the frequency range of power-line carrier equipment, in the range of 30 kHz to 500 kHz.

Power quality forms the basis of the global economy hence power quality is an issue for industrialists and economic leaders. There hardly can be a machine or product that doesn’t require electrical energy to be operated. Engines, automobiles, planes, computers, etc all need electricity in order to be in proper running conditions.&nbsp.
