Measurement of AC side harmonics of a DC metro railway

Abstract

The measured harmonic content (voltage and current) of the AC side of a rectifier substation of a DC electrified railway, Dubai Metro, is presented. The measured harmonic content is assessed for compliance against the permissible limits specified in IEEE Std 519. Some results are also given for the amplitude of characteristic and noncharacteristic harmonics with respect to the output current and delivered power.
