Wpływ jakości napięcia zasilającego na wyższe harmoniczne generowane przez układu napędowe prądu przemiennego oregulowanej prędkości

摘要

The paper presents results of computer simulations and experimental measurements for several topologies of AC adjustable speed drivesfitted with selected devices for harmonics mitigation. Simulation models of the drive topologies have been developed using the program EMTP-ATPand tested under adjusted levels of supply voltage distortion. Both experimental measurements and simulations demonstrate high harmonicmitigation effectiveness of broad-band harmonic filter and active front end rectifier.
