Dynamic reactive compensation: Reactive power fundamentals

The panel presentation is a tutorial on the concept of reactive power and discusses its implications in power systems. The impact of reactive power on the system voltage as well as on component ratings and component size is discussed. The concept of reactive power and the so called `instantaneous´ reactive power are presented. Finally, the mechanisms for generating reactive power using passive and active electrical apparatus are presented. The presentation is an introduction to more advanced dynamic compensation concepts to be covered by the other presenters.
