Fuzzy Logic-Based Vector Control of Permanent Magnet Synchronous Motor Using Stacked Matrix Converter for Railway Traction Applications

Recently, Permanent Magnet Synchronous Motors (PMSMs) have been widely accepted and employed in traction and railway transportation applications due to their various advantages such as small inertia, high efficiency and high torque density. In this paper, in order to use these motors as traction drives in an effective way, the vector control scheme is employed. In this strategy, the stator curr...

Power Quality in Railway Traction and Compensation by Combining Shunt Hybrid Filter and TCR

This paper analyses the quality of electricity in railway traction. Power quality characteristics have been measured as a case study in a traction sub-station in Tamil Nadu, India, where 1400 KVAR capacitor bank is installed. The actual data has been obtained through direct supply of traction load. Harmonics and various power quality problems are generated through the load of current. The emerg...

A Direct Power Feeding System for AC Railway Networks Using Modular Multilevel Converter

Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...
