Since the appearance of the second edition in , the overall energy situationhas changed considerably and this has generated great interest in non-conventional and renewable energy sources, energy conservation and manage-ment, power reforms and restructuring and distributed arrd dispersed generation.

Chapter t has been therefore, enlarged and completely rewritten. In addition,the influences of environmental constraints are also discussed. The present edition, like the earlier two, is designed for a two-semestercourse at the undergraduate level or for first-semester post-graduate study. Modern power systems have grown larger and spread over larger geographi-cal area with many interconnections between neighbouring systems. Optimalplanning, operation and control of such large-scale systems require advancedcomputer-based techniques many of which are explained in the student-orientedand reader-friendly manner by means of numerical examples throughout thisbook.

Electric utility engineers will also be benefitted by the book as it willprepare them more adequately to face the new challenges. The style of writingis amenable to self-study. Highlights of this edition are the five new chapters. Chapter 13 deals withpower system security. Contingency analysis and sensitivity factors aredescribed.

An analytical framework is developed to control bulk power systemsin such a way that security is enhanced. Everything seems to have a propensityto fail. Power systems are no exception. Power system security practices try tocontrol and operate power systems in a defensive posture so that the effects ofthese inevitable failures are minimized. Chapter 14 is an introduction to the use of state estimation in electric powersystems. We have selected Least Squares Estimation to give basic solution.

External system equivalencing and treatment of bad data are also discussed. The economics of power transmission has always lured the planners totransmit as much power as possible through existing transmission lines.

Difficulty of acquiring the right of way for new lines the corridor crisis hasalways motivated the power engineers to develop compensatory systems. Therefore, Chapter 15 addresses compensation in power systems. Both seriesand shunt compensation of linqs have been thoroughly discussed. Chapter 16 covers the important topic of load forecasting technique. Knowing load is absolutely essential for solving any power system problem.

Chapter 17 deals with the important problem of voltage stability. Mathemati-cal formulation, analysis, state-of-art, future trends and challenges arediscussed. Tata McGraw-Hill and the authors would like to thank the followingreviewers of this edition: Prof. Mohan, Anna University, Chennai; Prof. Bijweand Dr. While revising the text, we have had the benefit of valuable advice andsuggestions from many professors, students and practising engineers who usedthe earlier editions of this book.

All these individuals have influenced thisedition. We express our thanks and appreciation to them. Mathematical modelling and solution on digital computers is the only practicalapproach to systems analysis and planning studies for a modern day powersystem with its large size, complex and integrated nature.

The stage has,therefore, been reached where an undergraduate must be trained in the latesttechniques of analysis of large-scale power systems. A similar need also existsin the industry where a practising power system engineer is constantly faced withthe challenge of the rapidly advancing field.

This book has bedn designed to fulfilthis need by integrating the basic principles of power system analysis illustratedthrough the simplest system structure with analysis techniques for practical sizesystems. In this book large-scale system analysis follows as a natural extensionof the basic principles. The form and level of some of the well-known techniquesare presented in such a manner that undergraduates can easily grasp andappreciate them.

The book is designed for a two-semester course at the undergraduate level. With a judicious choice of advanced topics, some institutions may also frnd ituseful for a first course for postgraduates. The reader is expected to have a prior grounding in circuit theory and electricalmachines. He should also have been exposed to Laplace transform, lineardifferential equations, optimisation techniques and a fir.

ГЛАВА 107 Сьюзан понятия не имела, сколько прошло времени. Жжение в горле заставило ее собраться с мыслями. Стоя на ковре возле письменного стола, она в растерянности осматривала кабинет шефа. Комнату освещали лишь странные оранжевые блики.

Складывалось впечатление, что он отключился сам по. Сьюзан знала, что такое могло произойти только по одной причине - если бы в Следопыте завелся вирус. Вирусы были самой большой неприятностью, с которой сталкивались в своей работе программисты. Поскольку компьютеры должны были выполнять операции в абсолютно точном порядке, самая мелкая ошибка могла иметь колоссальные последствия.

 Con permiso! - крикнул санитар. Мимо стремительно проплыла каталка. Беккер успел отскочить в сторону и окликнул санитара.

Тогда она взяла послание домой и всю ночь просидела под одеялом с карманным фонариком, пытаясь раскрыть секрет. Наконец она поняла, что каждая цифра обозначала букву с соответствующим порядковым номером. Она старательно расшифровывала текст, завороженная тем, как на первый взгляд произвольный набор цифр превращался в красивые стихи.

Халохот был мертв. Беккер отшвырнул пистолет и без сил опустился на ступеньку. Впервые за целую вечность он почувствовал, что глаза его застилают слезы, и зажмурился, прогоняя влажную пелену. Он знал, что для эмоций еще будет время, а теперь пора отправляться домой. Он попробовал встать, но настолько выбился из сил, что не смог ступить ни шагу и долго сидел, изможденный вконец, на каменных ступеньках, рассеянно разглядывая распростертое у его ног тело.
