Dymola FMU

The idea was to merge two models (standard cycle model and engine specific cycle model) into one model to save time and facilitate development of new models. The current fmi standard did not support an easy way to do this. Two models are still used.

Input(s):

• Different sets of input parameters depending on if running a standard cycle or using measured data from site
• Examples of input are: -- Ambient conditions -- Power output set point -- Valve positions

Main feature(s):

• The fmu uses the inputs and runs a transient cycle of the gas turbine
• The cycle can be a pre-defined standard cycle, i.e. start, loading and stop or can mimic a cycle for a real engine, by using measured data
• After simulation a result file is generated, that can be used for different applications

Output(s):

• A large number of outputs are generated, but are the same regardless of if a standard transient cycle or a engine specific cycle has been simulated
• Examples of outputs are speed, pressure, temperature, mass flow etc.

• Component specific characteristic
• Control document
• Technical specifications of valves etc.

Tools that use the transient gas turbine model.

In-house models only available for Siemens Energy.
