ARRILLAGA POWER SYSTEM HARMONICS PDF

Covers major areas such as harmonic causes, effects, analysis, monitoring, penetration, and control. Also discusses the setting of harmonic standards, computer models of harmonic penetration, and the presentation of harmonic information. The topic of power system harmonics was covered for the first time 20 years ago and the first edition has become a standard reference work in this area. Unprecedented developments in power electronic devices and their integration at all levels in the power system require a new look at the causes and effects of these problems, and the state of hardware and software available for harmonic assessment. Following the successful first edition, this second edition of Power System Harmonics maintains the practical approach to the subject and discusses the impact of advanced power electronic technology on instrumentation, simulation, standards and active harmonic elimination techniques.

Following the first international conference on Power System Harmonics held in Manchester in , J. The book, co-authored by D. Bradley and P. Bodger and published in , has provided the basis for a variety of courses and workshops on power quality issues. It has also been of considerable assistance to power system designers. In the past two decades other books and an innumerable number of publications have appeared in the technical literature on the general topic of harmonics.

Acha and M. All these, however, have mostly included material coming out of academic research and on computer simulation techniques. In recent years there have been numerous requests for an update of our original text, maintaining the practical approach to the subject. Therefore the scope of this new edition is not particularly different from the original, namely to provide a general understanding of power system harmonics generation, their effects, monitoring, analysis and elimination, but taking into account the main developments particularly in power electronics accepted by the power industry in the past two decades.

It is impractical for most users to develop their own harmonic assessment programs. Thus the analysis sections of the book provide basic understanding of the techniques involved in harmonic assessment and rely on existing available software, with special emphasis on generally available programs such as EMTP and MATLAB.

The only exception is an advanced and complex frequency-domain program developed by the authors, called The Harmonic Domain, which is provided in CD-ROM form for demonstration purposes. We would like to acknowledge the contributions made to the development of this book by many of our colleagues, and in particular by P. Bodger, D. Bradley, G. Bathurst, S. Chen, A. Wood, B. Smith, E. Acha, J. Eggleston, G. Heydt, A. Medina, M. Viana Lisboa, S. Round, A.

Semlyen, R. Yacamini and J. When an electrical signal is sent to an oscilloscope its waveform is observed in the time domain; that is, the screen shows the signal amplitude at each instant in time. If the same signal is applied to a hi-fi amplifier, the resulting sound is a mix of harmonic frequencies that constitute a complete musical chord.

The electrical signal, therefore, can be described either by time-domain or frequency-domain information. This book describes the relationships between these two domains in the power system environment, the causes and effects of waveform distortion and the techniques currently available for their measurement, modelling and control. Reducing voltage and current waveform distortion to acceptable levels has been a problem in power system design from the early days of alternating current.

The recent growing concern results from the increasing use of power electronic devices and of waveform-sensitive load equipment. The utilisation of electrical energy is relying more on the supply of power with controllable frequencies and voltages, while its generation and transmission take place at nominally constant levels. The discrepancy, therefore, requires some form of power conditioning or conversion, normally implemented by power electronic circuitry that distorts the voltage and current waveforms.
