This paper describes techniques to be used to model megawatt Electrified Aircraft Propulsion (MW EAP) components, specifically motor/generators and inverters, DC-DC converters, and long power leads. The goal of this work is to provide a way to combine experimental measurements with analytical models in order to predict system stability of an integrated MW class power system without detailed electrical models of individual components. A simulation approach called subscale measurement is used to generate an impedance transfer function model of the high-power dynamometer system, in motor and generator mode. Models of the interconnecting cables between subsystems are also developed and presented. Model results are analyzed and compared. Future work describing system stability and power quality improvement approaches is discussed.
