EBSILON®professional
EBSILON®professional is a software package for the simulation and optimisation of energy technology systems developed by iqony. The software enables the planning, process engineering design and optimisation of power plants. The integrated component library allows users to assemble and thermodynamically simulate any configuration.
In collaboration with the provider, the DLR Institute of Solar Research expanded the EBSILON®professional planning tool to include solar thermal power plant components such as the solar library and the time series calculation. This makes it possible to thermodynamically model a complete solar thermal plant.
For the simulation of line-focussed systems, the software offers components for modelling collectors (parabolic troughs and linear Fresnel collectors), which can work with different heat transfer media such as oil, liquid salt or water/steam. Header components calculate both heat and pressure losses in the distribution and collection pipes in a solar field model.
There are two different components for solar tower systems: Various efficiency matrices can be defined in the heliostat field model, while the receiver model offers common loss calculation mechanisms. The component library is supplemented by two storage components, one for tank storage systems and one for indirect storage systems.
In addition to a large number of standard parameters, the user has the option of entering individual parameters, formulating their own model equations and switching model parts on and off.
Time series calculations
In order to be able to use the thermodynamic models directly for time series calculations, the basic functionalities of the programme have been significantly extended. This allows annual calculations to be carried out from an Excel environment. The software's scripting language defines instructions to enable both the precise selection of operating points in each time step and the control of the simulation directly in the model. This means that systems with several generators or consumers and with storage functionality can be simulated in thermodynamic detail.
The Institute of Solar Research uses the tool to analyse innovative solar power plant circuits of heat storage power plants and industrial energy supply solutions. The software is also used for the planning and operation of test plants.
