Electric power quality is the degree to which the voltage, frequency, and waveform of a power supply system conform to established specifications. Good power quality can be defined as a steady supply voltage that stays within the prescribed range, steady AC frequency close to the rated value, and smooth voltage curve waveform (which resembles a sine wave).
Harmonic frequencies are produced by the action of non-linear loads such as rectifiers, discharge lighting, or saturated electric machines. They are a frequent cause of power quality problems and can result in increased equipment and conductor heating, misfiring in variable speed drives, and torque pulsations in motors and generators.
Reactive power needs to be generated and distributed through a circuit to provide sufficient real power to enable processes to run. Reactive power increases significantly with increasing voltage as the reactance of equipment increases. Correcting this with voltage optimisation will therefore lead to a reduction in reactive power and improvement ...
Applied and Computational Harmonic Analysis is a bimonthly peer-reviewed scientific journal published by Elsevier. The journal covers studies on the applied and computational aspects of harmonic analysis. Its editors-in-chief are Ronald Coifman (Yale University) and David Donoho (Stanford University). [1]
IEC 61000-3-2 aims to set limits to the harmonic currents drawn by electrical apparatus and so maintain mains voltage quality. It is a compromise between cost and the performance of extra electronic front end circuits, the so called active power factor correcting circuits. With present day components with wide use, e.g. in fluorescent lighting ...
The Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy is a peer-reviewed scientific journal that covers research on the technology of energy conversion systems. The journal was established in 1990 and is published by SAGE Publications on behalf of the Institution of Mechanical Engineers. [1]
The publications of the Institute of Electrical and Electronics Engineers (IEEE) constitute around 30% of the world literature in the electrical and electronics engineering and computer science fields, [citation needed] publishing well over 100 peer-reviewed journals. [1]
Harmonic analysis is a branch of mathematics concerned with investigating the connections between a function and its representation in frequency.The frequency representation is found by using the Fourier transform for functions on unbounded domains such as the full real line or by Fourier series for functions on bounded domains, especially periodic functions on finite intervals.
