2 Basic Concepts

2.1  INTRODUCTION

In this chapter, a brief review of fundamental concepts associated with steady-state alternating current circuits, especially with three-phase circuits, is presented. It is hoped that this brief review is sufficient to provide a common base, in terms of notation and references, that is necessary to be able to follow the subsequent chapters.

2.2  COMPLEX POWER IN BALANCED TRANSMISSION LINES

Figure 2.1a shows a per-phase representation (or a one-line diagram) of a short three-phase balanced transmission line connecting buses i and j. Here, the term bus defines a specific nodal point of a transmission network. ...
