Abstract :
Development and refinement of 20 kHz testbed simulation for the Space Station Freedom electric power system is described and the model verification process demonstrated. The high degree of correlation between the testbed data and the simulation results is shown. Testbed simulations will be performed prior to hardware tests to uncover any hidden problems, and simulations will be substituted when hardware tests are not practical or convenient. The EASY 5 simulation package is used as the primary tool for this activity. Many of the component models, results of simulations, and results of model verification activity are presented
