Power sizing and power performance simulation tools for general EPS analyses

Several electric power system (EPS) modeling and simulation tools have been developed at Lockheed Martin that are being used in detailed EPS component designs and also in detailed EPS transient performance analyses. A consistent set of very detailed EPS components are used within each of the tools. The components can be chosen by the user to be very simple, such as time-averaged component values, or extremely detailed, such as instantaneous nonlinear models that have been verified against component test data. These tools have been used for a variety of satellite mission studies, and have been successfully used in both EPS component sizing studies and in detailed component and system transient performance calculations. Several EPS systems models are presented for discussion, the EPS component models are summarized in detail, and example results are included
