Abstract :
Voltage dips or power interruptions in the grid cause huge problems for the users. The ride-through behavior of frequency converters can be a very good solution to bridge the gap. But how does the whole drive system react in case of power loss? The kinetic energy recovery is only successful when all the important elements in the chain fit together. This paper reconsiders the topic on a power drive system level and gives practical information to the users, based on the experience of a drive manufacturer.
