| Distanzschutz mit Mikrorechnern
/ Koglin, H J ; Lobos, T
[I08/1980/P-128]
[ENY-ARTICLE-2008-058]
Nachdem erst vor kurzem in der Schutztechnik die Technologie der elektromechanischen Relais durch den elektronischen ("statischen") Schutz abgelöst wurde, stehen wir zur Zeit bereits wieder vor einer Wende: Die Technologie der Mikroprozessoren macht auch vor diesem Bereich nicht halt; im Gegenteil: der Mikrorechner ist für die schwierigen Meßaufgaben in der Schutztechnik geradezu prädestiniert.

| Real-Time Parameter Estimation of Signals in Converter Fed Drives using Adaptive Neural Networks
/ Lobos, T ; Koglin, H J ; Waclawek, Z
[ENY-ARTICLE-2008-031]
Frequency converter-fed induction motor drives were simulated using the EMTP-ATP (Electromagnetic Transients Program - Alternative Transients Program) The aim of the simulation investigations is to develop a feasible method for drive visualisation and for diagnosis of different unsymmetrical operations.
