Dear wgust (we don't know your real name...)
I am absolutely new to Modelica and have some questions. I'm doing my
thesis and have to design a controller for a power system consisting of an
exhaust turbine, a gear and a synchronous generator. First, I have to
simulate the system and to analyze its behaviour.
The reason for me for unsing Modelica are the free libraries wit ready
models for thermodynamics, mechanics and power systems. As my thesis
refers to a real system it is very important for the simulation model to
be very close in its behaviour to the real system . I'd like to ask
modelica experts if it is possible with OpenModelica and libraries and
SimForge to build a reliable system model and design a controller. How
long can it take to get started with Modelica and SimForge to be able to
do? How difficult is the usage of the libraries?
I am afraid that the current status of OpenModelica does not allow you
to re-use most of the stuff you need, in particular the fluid models and
the thermodynamic libraries. The plan is to improve the compiler, so
that this becomes possible, by June next year, if everything goes as
expected.
In the meantime you might start trying with other Modelica tools (e.g.
Dymola). If develpment of OpenModelica goes as planned, at some point
you should be able to switch tools but still keep the same source
Modelica code for you models.
Another alternative is that you write everything you need in Modelica
from scratch, without re-using existing libraries, but I'm not sure
whether this is a good way to use your time - it might actually be
better than doing the same thing with Simuilink, which is a less
appropriate simulation tool for this kind of problems.
Good luck!
