An experimental object-oriented modelling of an hydraulic valley

Abstract This communication presents an object-oriented modelling methodology for the development of complex systems simulators and an application to an hydroelectric system. The model structure is described by a multiport object-oriented diagram. Its implementation and simulation are based on the object-oriented modelling language Modelica© and on a multiformalism simulation platform Dymola©. System identification techniques arc used for both estimating the behavioural models of objects and for the calibration of the multiport diagram. The originality of this contribution is the introduction of the behavioural formalism of the systems theory in the object-oriented modelling framework.
