1. Development and Analysis of Small Signal DQ-Frame Model for Low Frequency Stability of Train Converters
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In order to meet the increasing demand for sustainable transportation, trains need to run with tighter schedules, more departures and more trains in depot. Multiple trains in depot has been linked to low frequency instability at many locations around the world. READ MORE

4. Pre-study of optical LED units for shunting signals
University essay from KTH/Hälsoinformatik och logistikAbstract : Alstom wanted to investigate the possibility of adapting its light emitting diode (LED) technology for shunting signals in train traffic. The LED technology uses 50V, but Alstom wants to adapt it for 12V. The LED technology is energy efficient but needs to be adapted for existing signal interlocking by drawing a higher current.

5. Stabilization of Constant Power Loads Using Model Predictive Control
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This thesis considers stabilization of constant power loads (CPLs) fed by a dcpower source through an input filter, using model predictive control (MPC).Train propulsion systems generally utilize electrical motors whose output torqueis tightly regulated by power converters. Often, these systems behave as CPLs. READ MORE
