An electrical network model for analysis is a representation of an electrical test platform. Such a model must be representative of the electrical behavior of the entire apparatus and the correct representation must be guaranteed both in steady state and during transients. Furthermore, the model must take into account changes in the operating point due to mechanical, thermal, environmental changes (for example for mechanical load shifts in terms of speed and torque for actuators / motors, voltage changes and transients on the network due to changes in external parameters, etc.).

The model also has other functions:

• • to support verification and validation activities: each test can be simulated in order to verify the good behavior included in the model;
  • to investigate verification and validation activities: the calibrated model is able to provide information that has not been measured during a test, and is necessary for the analysis;
  • for component sizing: The model can be used as a sizing tool for specifying the requirements of some components of the physical platform (for example, filters and heat sinks).

The power grid analysis model and the rig synergistically pursue the same goals. The rig extends the model to physical phenomena that have not been modeled, the model simulates configurations or parameter changes that cannot be physically performed on the rig.

Additionally, the power grid model will have the ability to anticipate problems on the test bench, and will also be used to scale up the plant in specific configurations (business jets, regional aircraft and helicopters).

The power grid model for analysis will be based on the integration of product models provided by different component manufacturers.

Most of these models should be provided in SABER format, while the power grid should be developed using multi-system simulation oriented tools. Therefore, a key step for multi-system modeling activities will be to use the conversion to non-proprietary models, but using free libraries such as MODELICA (CATIA V6) or EASY-5.

Given the scenario described above, the need arises to develop a software tool capable of converting power grid models from the SABER format to other types of multisystem simulation tools (e.g., MODELICA, EASY-5, CATIA V6, …). Such a tool accepts as input a generic SABER model and must produce as output an object that must be compatible with another software language.
