Designing an All-Electric Ship (AES) requires testing of the interaction between hundreds of interconnected power electronic subsystems built by different manufacturers. Such integration tests require large analog test benches or the use of actual equipment during system commissioning. Fully digital simulators can also be used to perform Hardware-in-the-Loop (HIL) integration tests to evaluate the performance of some parts of these very complex systems. This approach, in use for decades in the automotive and aerospace industries, can significantly reduce the costs, duration and risks related to the use of actual equipment to conduct integration tests. However the computational power required to conduct detailed simulation of such diverse and numerous power electronic components can only be achieved through the use of distributed parallel supercomputers, optimized for hard real-time performance with jitter in the order of a few microseconds. Such supercomputers have traditionally been built using expensive custom computer boards.
The following documents present the technology and performance achieved by the eMEGAsim Real-Time Power Grid Simulator used for this AES application. The model and methodology for conducting simulation of an AES Integrated Power System is also illustrated.
These posters were presented as part of Opal-RT's demonstration of Real-Time Simulation of AES Power Systems at the 2009 IEEE Electric Ship Technologies Symposium (ESTS) in Baltimore, Maryland in April 2009:
- Simulation Environment Description
- Real-Time Distributed Simulation during the Design Process
- All-Electric Ship Model Distribution & Performance
