ThermoSysPro is an open-source Modelica component library developed by EDF, focused on thermal-hydraulic, instrumentation, and control modeling. It is primarily designed for a wide range of thermal power generation systems, including nuclear power, fossil-fuel power plants, solar, biomass, and combined heat and power, and can also be used for simulating energy systems such as district heating networks and industrial processes. The library is released under the Modelica License 2 and can be used for teaching, academic, and industrial purposes.
In terms of functionality, ThermoSysPro provides more than one hundred model components, covering combustion chambers, heat exchangers, steam turbines, mechanical equipment, piping elements, and more. It supports single-phase and two-phase water/steam flows as well as flue gas flows. All components describe the static and dynamic behavior of systems based on first-principles physical laws, making the library suitable for studying thermal cycles across wide pressure and temperature ranges. The source material also notes that it has been validated against real industrial test cases in nuclear, thermal power, biomass, and solar applications, with test case models included in the library. This is valuable for both engineering credibility and reproducibility in teaching.
The library is developed in the Modelica language and primarily uses Dymola for development. It can also be combined with Persalys for model analysis, calibration, optimization, model reduction, and sensitivity analysis. The website provides entry points for Gitlab, Documentation, Publications, and related resources, although the captured content does not show documentation details. In terms of pricing, the source text does not mention any commercial fees, and the open-source license lowers the barrier to adoption. However, because it targets professional simulation of thermal systems, users need knowledge of Modelica, thermal hydraulics, and system modeling. It is not exactly lightweight for general developers.
Its strengths include a rich set of domain-specific components, open-source availability, suitability for industrial scenarios, and support from real-world test cases. Its integration with Persalys/OpenTURNS also enhances analysis and optimization capabilities. The drawbacks are that commercial support, SLA, or training services are not disclosed, and it depends on the Modelica toolchain, so beginners face a relatively long learning curve. It is better suited to R&D departments at energy companies, simulation teams at thermal power plants, control validation engineers, and universities or research institutions.
The source text does not provide information about access from China. Domain reachability, download speed, and Gitlab access stability would need to be tested in practice; if access is restricted, a mirror or proxy may be required. Alternative or complementary options worth considering include Modelica Standard Library, component libraries in the OpenModelica ecosystem, Buildings Library, and ThermoPower. Overall, ThermoSysPro is a high-value specialist library for engineering and research rather than a general-purpose development tool.
