CHAPTER 2

Power System Network Matrices—1

2.1 Introduction

Various studies have to be conducted for the analysis of steady state or dynamic state of a power system. As discussed in Chapter 1, a study is unfolded in three stages: network modelling stage, mathematical modelling stage and solution stage.

In the network modelling stage, various components of the power system are represented by their individual electrical equivalents, converting the single-line diagram of the power system network into an electrical network consisting of active and passive elements.

The electrical network model is converted into a suitable mathematical model comprising of algebraic or differential equations for performing network analysis. For the sake of convenience, ...
