The architectural level corresponds to "simple" phasor theory resulting in a quasi-static description of the system. The functional level of detail uses dynamic phasors to cover dynamic effects in the models. The level of detail can be selected via parameters in the components.Additionally the EPSL enables the description of harmonics of the fundamental AC frequency, which can be either constant or variable. Currently the AC components are either single or three-phased, whereas other phase numbers would be straight-forward to be added due to the generic modeling approach of components.

Systems Fluid Dynamics Library for Coarse-Grid-CFD-simulation with Modelica

FLUID DYNAMICS LIBRARY (FFLY)

• The Systems Fluid Dynamics library carries out CFD-Simulations using Modelica language and provides standard interfaces to 1D-Modelica-models for a seamless connection. The fluid dynamics are purely modelled by using Modelica language.

• The Systems Fluid Dynamics Library allows the modelling and simulation of gas flows (e.g. humid air) in three-dimensional spaces. At the boundaries of the grid model local boundary conditions may be defined, which can change transiently or wall and window models can be attached. The maximum resolution of the cubic grid depends on the capacity of the computer hardware and is typically limited to about 1.000 - 2.000 cells. Larger spaces may even be modelled through the definition of symmetry boundary conditions.

Behavior Optimization (DOZ)

• The Systems Behavior Optimization role optimizes or "tunes" system parameters such that the system behavior is improved. This provides tools to benifit from numerical optimization algorithms without special knowledge about the internals of the algorithms. The parameters that are tuned are often referred to as tuners. Mathematically, the tuning procedure is formulated as multi-criteria parameter optimization: Parameters are calculated to minimize criteria which express in mathematical terms what “improvement” shall mean. Criteria values are usually derived from simulation results, e.g., the overshoot or rise time of a response, but they can also be derived by other analysis procedures, such as frequency responses or eigenvalue analysis.

FLEXIBLE BODIES LIBRARY (FBY)

• The Modelica based Systems Flexible Bodies Library enables the efficient mathematical modeling of flexible bodies such as components of multi-body and arbitrary physical systems.

• This library provides 4 Modelica model classes. Three of these classes are based on an analytical description of flexible bodies with a characteristic geometrical shape such as beams, annular plates and thermos-elastic annular plates. These model classes are completely implemented in Modelica and its instantiation and visualization is entirely controlled by Modelica user input parameters. The fourth class, the ModalBody is supposed to model flexible bodies with a general geometrical shape, whose mechanical description is based on an underlying finite element model. Therefore, a ModalBody relies on a preprocessing step and requires two input files in order to specify the associated parameters and visualization data.
