Object-Oriented Modelling & Simulation of Power Plants with Modelica

This paper presents and discusses the application of the object-oriented modelling paradigm to thermo-hydraulic systems, with particular reference to fossil-fired and nuclear power plants. As a result, a particular modelling approach is proposed and motivated. The paper also presents the ThermoPower Modelica library, developed at the Politecnico di Milano along the proposed approach, and made available to the scientific and professional community within the terms of the Modelica license. Some application cases involving ThermoPower are briefly reported.
