An Intelligible and Practicable Methodology for Power System Dynamic Analysis : Part 1: System Modeling : Part 2: Component Modeling

Abstract

This paper summarizes a compact process of power system dynamic analysis that – indifferent of the level of detail observed in the electrical modeling of any given component – allows for appropriate power network modeling and analysis in a way that appears conceptually straight forward as well as practicable. Based on describing all power system components in terms of discrete elements, the power network related modeling is onducted within the d–q axis frame of reference. Central to the methodology is the definition of a standard electrical circuit model to act as common network building block for all power network components. Part 1 gives an overview of component- and system modeling as well as model application. A small example illustrates the methodology. Part 2 treats component modeling in depth. Some overview observations on the detailed analysis of unbalanced conditions are also made.
