This paper presents the lessons learnt during the development of a library for the modelling of district heating systems (DH systems), especially focusing on the distribution network. The library was built based on elements from the Modelica Standard Library (Modelica Association, 2012) and the NewThermal library (Lopez, del Hoyo, 2013). The modelling strategy chosen is described. Furthermore, the requirements established by the DH networks are set out as well as the models created in response to these demands. Finally, the artificial diffusion phenomenon, present in the simulation of this kind of large thermo-fluid systems, is described.

Keywords: district heating modelling; plastic pipe model; buried pipe model; numerical diffusion; courant number; transport delay; thermo-fluid simulation
