Database/power‐flow interlinkage of a stand‐alone power system training simulator

Abstract

A training simulator imitates the performance of a power system by application of dynamic models for power units, networks and loads. The results must be displayed in a form related to real operation. This implies a presentation of the power system both on operational and on model level, and transitions between both levels. The GDL‐system allows to describe the whole operational stock of objects, e. g. for substations, bays, lines, protection and auxiliary equipment alarms, including their potential topology, in format‐free alphatext. This source is translated into a data model according to general rules. From the data model an operational man/ machine interface is automatically derived. The dynamic model of the simulator was already presented by K. Dickers and D. Rumpel in „Modelling for Grid Restoration Studies „(Electr. Power&Energy Systems Vol. 9 (1987) No. 1, pp. 45‐55). The present paper shows, how the power flow of the dynamic model is automatically linked to the GDL data model, without further program adaptions or parametrizing efforts on model level.
