Kurzfassung englisch:
A mathematical physical model for dynamic simulation of
flow and temperature in district heating networks (DHN) is
proposed. The network structure is described by means of a
graph-theoretical approach where the network elements are
pipe sections, consumers and heat sources. The governing
equations for hydraulic flows and heat distribution through
pipe networks are presented. In addition, proper orthogonal
decomposition is outlined and applied for obtaining a
reduced model representation of the hydraulic equations. It
is shown that the proposed methods are suitable for predicting
flow and temperature values at each consumer with
minimal average error and can therefore be used as a conceptual
tool for operational optimization of district heating
