Verification and analysis for small signal stability of Electric Power Systems for the international space station/JEM

The International Space Station (ISS) electric power system is now the world´s largest dc power system in space. The analysis and design of electric stability, power quality, power management and protection for the ISS were critical issues and concerns from early design phase. Especially, the design evaluation and verification for the electric stability must be required to the all ISS modules in every design phase. Japan Aerospace Exploration Agency (JAXA) is responsible for the design and verification of Electric Power System (EPS) in Japanese Experiment Module (JEM). This paper describes the approach of the small signal stability analysis and verification showing JEM EPS simulator test data.
