Adjustable Speed Drive and Power Rectifier Harmonics-Their Effect on Power Systems Components
TLDR
The use of the electrochemical rectifiers and the increasing application of ac and dc adjustable speed drives dictates that the effect of harmonic "pollution" on other equipment in the power system be considered as discussed by the authors.Abstract:
The use of the electrochemical rectifiers and the increasing application of ac and dc adjustable speed drives dictates that the effect of harmonic "pollution" on other equipment in the power system be considered An example power system is examined, and the necessary calculations are performed to show the effect harmonics have and investigate the probability of a harmonic resonance situation occurring The tolerances that various power system components have to harmonic currents and voltages are examined These components include transformers, reactors, capacitors, cable, switchgear, relaying, generators, and motorsread more
