AC railway electrification systems — An EMC perspective

AC cables strengthening railway low frequency AC power supply systems – a deepened study

In railway power supply systems using AC frequencies lower than the public grids of 50/60 Hz, high voltage AC overhead transmission lines in railway grid frequency are used as one measure of strengthening the systems. An increased resistance to overhead high voltage AC transmission lines, may motivate cables for future railway power systems. With the frequency of 50/60 Hz, reactive power produc...

An EMC Perspective on Data De-Duplication for Backup

Emc Avamar Integration with Emc Data Domain Systems

This white paper highlights integration features implemented in EMC Avamar with EMC Data Domain deduplication storage systems to allow high-speed data backup directly to Data Domain systems. The components outlined in this paper will provide IT backup administrators & consultants with a technical foundation to architecting efficient combined data deduplication backup solutions.

A comprehensive control strategy of railway power quality compensator for AC traction power supply systems

The development of electrical railway systems leads to critical power quality problems in the power grid. This paper discusses a kind of half-bridge-based railway power quality compensator system (HBRPQC) that can compensate negative sequence currents, harmonics, and reactive power simultaneously. In order to keep the HBRPQC performance efficient for the different kinds of transformers used in ...
