A Harmonic Transfer Function Model for a Diode Converter Train

Möllerstedt, Erik and Bernhardsson, Bo LU (2000) In IEEE Power Engineering Society Winter Meeting, 2000. 2. p.957-962
Abstract
A method for analysis of electric networks with nonlinear and switching components is presented. The method is based on linearization around the nominal AC voltage, which results in linear time periodic (LTP) models. For nonlinear and switching components, there is coupling between different frequencies, which may cause stability and resonance problems. The models capture this coupling and can thus be used for small signal stability and robustness analysis. A short introduction to transfer functions for LTP systems is given. To illustrate the method, an LTP model for the Adtranz locomotive Re 4/4 is derived. The system consists of an AC-side with a transformer, and a DC-side with a DC motor and a smoothing choke. The AC-side and the... (More)
