Satellite's Energy Balance, Modelling and Sizing Tool with Ecosimpro

This paper present the research, development and implementation of a Spacecraft model for the realization of an Electrical Power Subsystems (EPS) energy balance and sizing tool. Developed within the EcosimPro environment, this tool is able to conduct energy balance simulations for virtually any type of mission orbit and multiple power architectures. It comprehends mathematical models of key power units such as Batteries, Solar Arrays (SA) and Power Conditioning Units (PCU), while it also implements, in a multidisciplinary system concept, components to process SC orbit and attitude parameters, as well as dynamically changing thermal predictions.
