Comprehensive power analysis

Power is a system level tool to define the power architecture of a satellite. It computes the electrical and thermal behaviour of a schematically defined architecture.  A schematic editor interface allows to build the power architecture with various elements such as solar array generators, batteries, and regulators.

Then a power solver computes the in orbit electrical performances of the architecture, taking into account the constraints due to the space environment (radiation, thermal, seasonal effects...). The power application globally transforms the electrical architecture model into a mathematical model. 

A complete power analysis of a space system (orbiting around a planet or along an interplanetary trajectory) can then be performed thanks to the power solver included in thermisol. The results of thermal computation (external fluxes, thermal couplings, temperatures) are accessible by the xthermica application. Thus, in order to take into account the space environment (external fluxes, thermal effects …) in the power analysis, the power application includes the thermica application.

Compute thermal and electrical behaviour

Integrated solver

The application offers a complete solution to compute the in-orbit electrical performances of an architecture.

It offers the possibility to create a geometrical model and define a mission to compute the external fluxes and radiative couplings.

A coupled thermal power solver allows to perform complete analyses taking into account thermal aspects due to space environment and the possibility of linking the geometrical/thermal model and the electrical architecture via thermal node numbers.

Build electrical architectures

Schematic editor

An interactive schematic editor allows you to build the electrical architectures.

A set of generic components is provided, including solar arrays, batteries, regulators, diodes, resistances, power loads and capacitances. 
This editor combines electrical, thermal and logical components.

Additionally, users can program their own components and reuse them for further analyses.

Complete analysis suite

Thermal & electrical

Power integrates all features of thermica to enhance power analysis.

It includes a radiative exchange factors computation module based on a multi-threaded ray-tracing algorithm.

Solar flux is computed based on the sun’s position, using an efficient ray-tracing algorithm. It also calculates infrared (IR) and albedo fluxes from planets or moons.

Please have a look at the thermica page for more information.
