Power

The Power application is based on:

• An interactive schematic editor to build the power architecture with various elements such as solar arrays, batteries and regulators, taking into account electrical and thermal aspects

• The computation of external fluxes and radiative couplings (with geometrical model and mission definition)

• The Thermisol solver, which is a coupled thermal power solver, to compute the electrical and thermal behaviour of the system

It is a complete solution to compute the in-orbit electrical performances of an architecture:

• Possibility to create a geometrical model and define a mission to compute the external fluxes and radiative couplings

• Geometrical (thermal) model and electrical architecture can be linked via thermal node numbers

• A coupled thermal power solver allows to perform complete analyses taking into account thermal aspects due to space environment

An interactive Schematic editor:

• An editor to build the electrical architecture
• Set of generic components are provided with the application: solar array, battery, regulator, iode, resistance, power load, capacitance
• Combine electrical, thermal and logical networks of components

Component editor:

• An editor to build the electrical architecture
• Set of generic components are provided with the application: solar array, battery, regulator, diode, resistance, power load, capacitance
• Combine electrical, thermal and logical networks of components
• User can program his own components using MORTRAN and C and reuse them for further analyses via the Graphical User Interface

Systema-Power embeds all the possibilities of Systema-Thermica to feed the power analysis:

• Radiative exchange factors computation module based on an multi-threaded ray-tracing algorithm It allows handling realistic thermo-optical properties:
  • Absorptivity / emissivity
  • Specular / diffuse reflection
  • Specular / diffuse transmission
  • Refractive index
• Solar & planets fluxes:
  • Computed as function of the position of the Sun
  • Efficient ray-tracing algorithm
  • Planet (or moon) IR and albedo fluxes
