Conceptual Design

EBSILON®Professional not only simulates part integration but also calculates wear and contamination effects due to varying efficiency, environmental conditions, and loads. It helps evaluate repowering or retrofitting benefits and timing.
The tool includes standard working fluids, user-defined fluids, and compatible fuels. It boasts a detailed coal database with chemical compositions and calorific values by source.

Detailed Design

Constructing and modifying energy and power plant systems requires precision planning and early performance testing. EBSILON®Professional allows you to model thermodynamic cycle processes and design entire power plants on your computer.
The tool includes calculation modules to define models. In design mode, input parameters determine design conditions, mapping your cycle's topology. The design mirrors your plant, with data automatically validated. This process is reliable and robust, supported by a universal calculation approach and a powerful solution algorithm.

Acceptance Test

Power plants undergo rigorous testing before becoming operational. This critical phase assesses the performance and safety of every plant component and the entire system. Environmental conditions and load scenarios are scrutinized, with data displayed and evaluated in real time. EBSILON®Professional excels at identifying sources of efficiency issues and revealing potential financial losses.


For power plant operators, the primary challenge lies in maximizing availability while maintaining performance as close to optimal as possible. However, defining what optimal performance entails precisely is often a complex task.
EBSILON®Professional addresses this challenge by estimating the likely optimum performance level. Its thermodynamic model incorporates all relevant variables and conducts real-time calculations. Furthermore, EBSILON®Professional can detect even minor deviations between the model and the actual plant, allowing for early corrective actions.

Go Limitless with EBSILON®Professional

In principal, EBSILON®Professional does not limit the details of the model. 

The interface between EBSILON®Professional and SR::x enables seamless data exchange between the model and the archive.

The combination of EBSILON®Professional and SR::EPOS allows the online calculation model to function offline as well. Should SR::EPOS identify any weaknesses in the power generation process, data from that specific point in time can be sent to EBSILON for thorough offline analysis.
