Harmonics propagation in industrial networks in the range of 2 to 150kHz

摘要

The aim of this paper is to investigate the harmonics propagation in industrial networks. The harmonics are studied in the frequency range of 2 to 150 kHz. In this frequency range, there are only few constraints due to standards for harmonics generation and therefore a great part of power electronic converters are designed with a switching frequency within this range. This paper will focus on methodologies to measure the harmonics in an existing electrical network. The measurements will be based on both voltage and current measurements. The harmonic propagation through the network will then be investigated and discussed.
