[PDF] Handbook of Power Quality by Angelo Baggini

PREFACE:

Power high quality (PQ) points are comparatively new: years in the past this was an issue regarding solely energy stations and arc furnace engineers. It is just lately that {the electrical} engineering group has needed to cope with the evaluation, analysis and resolution of PQ issues, even when it has not turn into a serious subject within the trade. Professionals are being confronted with PQ points each day, but solely the newest technology of engineers has been educated to face and clear up these points.

The primary purpose might be attributable to the truth that PQ is a posh space overlaying many alternative matters. That is additionally one thing that makes a complete guide troublesome – every PQ subject can warrant a complete guide, however time is an increasing number of a constraint.

If PQ points utilized to utility networks are comparatively new, the identical ideas utilized to buyer installations and gear have attracted the eye of {the electrical} world solely in actually latest instances. The issues associated to PQ are sometimes troublesome to resolve, and should permit totally different options, so the selection just isn’t all the time easy for these engineers and professionals who aren’t educated in PQ.

The optimum resolution to a PQ drawback is often a combination of options for a particular state of affairs. In such a state of affairs, it’s essential to determine that drawback and suggest totally different options to permit the technicians to make the optimum alternative. Analysis of options might be the important thing aspect in PQ drawback fixing, mainly for financial causes.

Really, some options require greater investments, and thus the mandatory administration approval, however managers often lack the data to judge the issues correctly. For these causes, in 2000 a gaggle of lecturers and industrialists launched a cultural programme (www.lpqi.org) co-founded by the European Fee and absolutely devoted to PQ from the attitude of not simply energy suppliers however electrical energy customers too.

Seven years later this program has greater than 100 companions all over the world and quite a few sub-projects targeted on particular points associated to PQ. It was at one of these, LPQIves (LPQI Vocational Instructional System), through the Berlin assembly in April 2005, that the thought for this guide was born. Principally, the goal of the LPQIves challenge was to develop a system of vocational coaching consisting of methodology and content material and, in some nations, skilled certification.

The members of this challenge got here to the conclusion that the guide must be on system elements. The authors felt that the guide must be a guide for individuals on instructional programs. Moreover, the guide can function a reference guide for lecturers and a handbook for college kids on common college programs, and as a guidebook for individuals who search background data on sensible options to PQ issues.

The distinctive character of the guide is a well-balanced one between a scientific strategy and sensible data which can be utilized in on a regular basis conditions by individuals who have solely a elementary electrical engineering background. To mirror this, one of the primary selections taken by the authors was as an example every chapter with a case research of a sensible software, its measurements and resolution.

This multi-use strategy makes the guide very complete, apply oriented and engaging for a comparatively broad viewers: specifically, scientists on the lookout for hyperlinks between their particular area and different PQ domains; engineers searching for a technique and data on the identification, evaluation and resolution of a PQ drawback; electrical energy customers who want explanations of totally different PQ phrases and definitions; managers on the lookout for background data on the financial penalties of PQ; and college students who require a complete guide overlaying the entire spectrum of PQ.

With the intention to contemplate PQ from totally different views and matters, this guide has been organized to cowl 5 ‘themes’. The primary is devoted to energy system points. The second is absolutely devoted to PQ phenomena in phrases of physics, parameters, measurements, sources and mitigations. The final three are devoted to PQ in apply, PQ issues and economical features of PQ.

The case research and different particular content material from every chapter are additionally out there on the companion web site, www.wiley.com/go/powerquality Earlier than you start what I hope is attention-grabbing studying, let me point out that, though I used to be nonetheless younger on the time of the 2005 Berlin assembly, previous to coordinating this group of inventive authors all over the world, I’ve been indicated as the principle creator of this guide.

Book Description:

Due to the complexity of power systems combined with other factors such as increasing susceptibility of equipment, power quality (PQ) is apt to waver. With electricity in growing demand, low PQ is on the rise and becoming notoriously difficult to remedy. It is an issue that confronts professionals on a daily basis, but few have the required knowledge to diagnose and solve these problems.

Handbook of Power Quality examines of the full panorama of PQ disturbances, with background theory and guidelines on measurement procedures and problem solving. It uses the perspectives of both power suppliers and electricity users, with contributions from experts in all aspects of PQ supplying a vital balance of scientific and practical information on the following:

• frequency variations;
• the characteristics of voltage, including dips, fluctuations and flicker;
• the continuity and reliability of electricity supply, its structure, appliances and equipment;
• the relationship of PQ with power systems, distributed generation, and the electricity market;
• the monitoring and cost of poor PQ;
• rational use of energy.

An accompanying website hosts case studies for each chapter, demonstrating PQ practice; how problems are identified, analysed and resolved.  The website also includes extensive appendices listing the current standards, mathematical formulas, and principles of electrical circuits that are critical for the optimization of solutions.

This comprehensive handbook explains PQ methodology with a hands-on approach that makes it essential for all practising power systems engineers and researchers. It simultaneously acts as a reference for electrical engineers and technical managers who meet with power quality issues and would like to further their knowledge in this area.
