Abstract

In power plant applications; detailed transient analysis of the evaporator results in very large fluid systems; i.e. the model consists of many equations. This is because the evaporator has many tubes and the spatial discretization has to be quite fine in order to appropriately model transient evaporation processes. In such cases; due to performance and workflow reasons; we use a specialized in-house tool Dynaplant. Coupling between Dynaplant and a Modelica-simulator helps to benefit in addition from the possibility of rapid development of new components in Modelica.

Here; it is shown; how the Functional Mock-up Unit (FMU) export from a Modelica model can be used to perform a co-simulation with Dynaplant and an FMU simulator. The FMU is defined via the Functional Mock-up Interface (FMI) for Model Exchange v1.0. Advantages but also restrictions and challenges are covered.
