Analysis of the stability margins of the Space Station Freedom Electrical Power System

Abstract

There is a need to define verifiable and testable stability margins for the Space Station Freedom Electric Power System Primary. Source/load impedance ratio margins are analyzed as candidates for assessing the power system stability. Limitations, as well as the advantages of the impedance ratio method, are discussed. A correlation is established between using this method and eigenvalue analysis as well as large signal studies.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
