called the power factor angle and the cosine of this angle is called the power factor. Power factor may be defined also as the ratio of the real power to the apparent power whose value lies between 0 and 1 and it is dimensionless quantity.

&CHAPTER 7 Power Flow Analysis 7.1 INTRODUCTION Power flow analysis is concerned with describing the operating state of an entire power system‚ by which we mean a network of generators‚ transmission lines‚ and loads that could represent an area as small as a municipality or as large as several states. Given certain known quantities—typically‚ the amount of power generated and consumed at different locations—power flow analysis allows one to determine other quantities. The most important
