Electrified Railway

Electrified railway traction transformer is a pivot that connects the electric locomotive and the public grid. Therefore, power quality problems caused by electric locomotive such as three-phase voltage imbalance, great voltage fluctuation and high harmonic content can be transmitted to the public grid via the traction transformer. To solve this problem, the solution of two sets of single-phase SVG (Static Var Generator) in back-to-back operation to solve power quality problems of the electrified railway is raised. This solution has been proved by practice effective in improving power quality of the traction transformer.

This paper explores methods to improve the power quality of large, single-phase, thyristor controlled equipment within industrial plants. An advanced shunt single phase power filter for the compensation of instantaneous harmonic current components in direct coupled booster melting in glass furnaces is presented. The validity of the excellent filtering characteristics is verified by a previous installation.

Technical Requirements

The power circuit arrangements of on-board high-voltage static converters fed from a 3000 V AC single-phase network that in the general case produce multi-channel AC and DC output voltages are considered. The basic technical requirements posed to such converters are formulated. The general structural diagram of high-voltage converters with improved electric power consumption quality is given. Possible power circuit arrangements for the high-voltage converter input unit based on single-phase input current correction devices are considered. A classification and criteria for comparative evaluation of the possible power circuit arrangements of these devices are proposed. The information presented in the article will be of interest for specialists engaged in designing on-board electrical systems involving high-voltage converters that must comply with strict requirements for the quality of consumed single-phase input current.
