Preface to Power Quality In Electrical Machines and Power Systems

The elevated use of energy digital elements inside the distribution system and the reliance on renewable vitality sources which have converters as an interface between the supply and the facility system result in energy high quality issues for the operation of machines, transformers, capacitors, and energy methods.

The topic of energy high quality may be very broad by nature. It covers all facets of energy system engineering from transmission and distribution degree analyses to end-user issues.

Subsequently, electrical energy high quality has turn out to be the priority of utilities, end-users, architects, and civil engineers in addition to producers.

The ebook is meant for undergraduate or graduate college students in electrical and different engineering disciplines in addition to for professionals in associated fields.

It’s assumed that the reader has already accomplished electrical circuit evaluation programs overlaying primary ideas comparable to Ohm’s, Kirchhoff’s, Ampere’s and Faraday’s legal guidelines in addition to Norton and Thevenin equal circuits and Fourier evaluation.

In addition, data of diodes and transistors and an introductory course on vitality conversion (overlaying vitality sources, transformers, easy management circuits, rudimentary energy electronics, transformers, single-and three-phase methods in addition to numerous rotating machine ideas comparable to brushless DC machines, induction and synchronous machines) is fascinating.

This ebook has advanced from the content material of programs given by the authors on the College of Colorado at Boulder, the Iran College of Science and Know-how at Tehran, and the Curtin College of Know-how at Perth, Australia.

The ebook is appropriate for each electrical and non-electrical engineering college students and has been significantly written for college kids or working towards engineers who wish to educate themselves via the inclusion of about 150 software examples with options.

Greater than 700 references are given on this ebook: principally journal and convention papers in addition to nationwide and worldwide requirements and tips. The Worldwide System (SI) of items has been used all through with some reference to the American/English system of items.

The ability high quality of energy methods impacts all linked electrical and digital gear and is a measure of deviations in voltage, present, frequency, temperature, power, and torque of explicit provide methods and their elements.

In current years there was a substantial improve in nonlinear masses, specifically distributed masses comparable to computer systems, TV screens and lighting.

These draw harmonic currents which have detrimental results together with communication interference, lack of reliability, elevated working prices, gear overheating, machine, transformer and capacitor failures, and inaccurate energy metering.

This topic is pertinent to engineers concerned with energy methods, electrical machines, digital gear, computer systems, and manufacturing gear.

This ebook helps readers to grasp the causes and results of energy high quality issues comparable to nonsinusoidal wave shapes, voltage outages, harmonic losses, origins of single-time occasions comparable to voltage dips, voltage reductions, and outages, together with strategies to mitigate these issues.

Analytical in addition to measuring strategies are utilized to energy high quality issues as they happen in present methods based mostly on central energy stations and distributed technology primarily counting on renewable vitality sources.

It’s important for every energy engineering scholar and skilled who’s energetic within the space of distributed methods and renewable vitality that he/she is aware of options to energy high quality issues {of electrical} machines and energy methods:

This requires detailed data of modeling, simulation and measuring strategies for transformers, machines, capacitors, and energy methods, specifically elementary and harmonic energy circulate, relaying, reliability and redundancy, load shedding and emergency operation, islanding of energy system and its voltage and frequency management, passive and energetic filtering strategies

And vitality storage mixed with renewable vitality sources. Intimate data of tips and requirements in addition to trade laws and practices is indispensable for fixing energy high quality issues in a cheap method.

These facets are addressed on this ebook which can be utilized both as a educating software or as a reference ebook.

Key options:

It supplies theoretical and sensible perception into energy high quality issues of machines and methods.

125 sensible software (instance) issues with options.

Issues on the finish of every chapter coping with sensible functions.

Appendix with software examples, some are carried out in SPICE, Mathematica, and MATLAB.

Power Quality in Power Systems and Electrical Machines, Second Edition PDF

Author(s): Fuchs, Ewald; Masoum, Mohammad A. S

Publisher: Academic Press/Elsevier, Year: 2015

ISBN: 0128007826,978-0-12-800782-2

Description:
The second edition of this must-have reference covers power quality issues in four parts, including new discussions related to renewable energy systems. The first part of the book provides background on causes, effects, standards, and measurements of power quality and harmonics. Once the basics are established the authors move on to harmonic modeling of power systems, including components and apparatus (electric machines). The final part of the book is devoted to power quality mitigation approaches and devices, and the fourth part extends the analysis to power quality solutions for renewable energy systems. Throughout thebookworked examples and exercises provide practical applications, and tables, charts, and graphs offer useful data for the modeling and analysis of power quality issues.

Provides theoretical and practical insight into power quality problems of machines and systems, enabling the reader to solve the power quality problems that they encounter
Worked examples and end of chapter exercises (with available solutions) show practical applications of the material discussed in the chapter
New to this edition: identifies problems and solutions associated with renewable energy sources, provides more practical examples, and provides a website with downloadable examples using SPICE, Mathematica, and Matlab©
