A new open source Modelica library called “ThermoSysPro” has been developed within the framework of the ITEA 2 EUROSYSLIB project. This library has been mainly designed for the static and dynamic modeling of power plants; but can also be used for other energy systems such as industrial processes; buildings; etc.
To that end; the library contains over 100 0D/1D model components such as heat exchangers; steam and gas turbines; compressors; pumps; drums; tanks; volumes; valves; pipes; furnaces; combustion chambers; etc. In particular; one and two-phase water/steam flow; as well as flue gases flow are handled.
The library has been validated against several testcases belonging to all the main domains of power plant modeling; namely the nuclear; thermal; biomass and solar domains.
The paper describes first the structure library. Then the test-case belonging to the thermal domain is presented. It is the dynamic model of a combined cycle power plant; whose objective is to study a step variation load from 100% to 50% and a full gas turbine trip. The structure of the model; the parameterization data; the results of simulation runs and the difficulties encountered are presented.
