The main objective of the current proposal was the development of an Electrical Network Analysis Model (ENAM) in Saber simulation environment and at behavioural modelling level. The model was used for the analysis of power quality, stability, and reliability of different configurations for the Electrical Test Bench (ETB). The proposal was based on the following key points:
- a detailed Saber model for the ENAM will be implemented in order to perform short transient analyses. Starting from the literature regarding electrical equipment modelling, first a mathematical model will be derived. Successively, it will be translated into an electrical scheme adopting Saber standard library elements where possible, or user-defined components implemented in MAST code as an alternative. The ENAM will be equipped with a high-level supervisory control scheme, in order to manage failures. About testing process, a set of devoted tests will be performed, mainly referring to required stability, power quality, reliability and failure mode behaviour.
- a devoted software will be implemented in order to interface with the Saber models and perform the required tests. The software will be implemented as standalone, however requiring the presence of a full Saber package installed on the target machine, but hiding to the user the complexity of the Saber environment. The devoted software will use an external mathematical calculation environment (e.g. Matlab) for implementing the post-processing functionalities above reported (i.e. power quality, failure mode and reliability analysis)
The proposed project followed a typical workflow for both modelling process and software development basic tasks.
The modelling activities were based on main theoretical analysis, mathematical formulation, models implementation and results verification task. On the other hand, the software development workflow was based on requirements analysis, specs derivation, design, implementation, testing and validation.
The main objective of MAS DE NADA was the development of an Electrical Network Analysis Model (ENAM) in Saber simulation environment and at behavioural modelling level, interacting with a software tool to be implemented, in order to perform a number of analyses. Specifically, the MAS DE NADA tool interacts with the ENAM Saber model in order to perform analyses of power quality, stability and failure mode of different configurations for the Electrical Test Bench (ETB).
The complexity of the Saber ENAM model is completely transparent to the MAS DE NADA tool user, that uses an intuitive GUI in order to perform the different analyses. Hence the project was based on the following key points:
- a detailed Saber model for the ENAM has been implemented in order to perform short transient analyses. In addition to the Saber models delivered by the equipment supplier, some other has been delivered and integrated into a global ENAM architecture, in conjunction with the available supplier models. The ENAM arranged schematic has been tested in order to evidence its performances and absence of destructive phenomena (e.g. overcurrents, overvoltages) on the correspondent ENAM, configured as a virtual representation of the Copper Bird electrical test bench.
- a user-friendly software has been implemented in order to interface with the Saber ENAM model and perform the required tests. The software has been implemented as standalone, however requiring the presence of both the Saber schemes and a full Saber package installed on the target machine, but hiding to the user the complexity of the Saber environment. The MAS DE NADA software uses specific AIM language scripts for implementing the post-processing functionalities (i.e. power quality, fault tree analysis, industrial stability analysis)
