Analytical and circuital modeling of commutation transients in phase-split synchronous motors supplied by multiple load commutated inverters

, 2008
Phase-split synchronous motors supplied by multiple three-phase Load Commutated Inverters are of importance in high power applications. A criticality of such systems is the possibility that commutations within different stator windings may overlap ...

Precision enhancement of the traditional sub‐synchronous analysis by using frequency components of instantaneous magnetic flux

IET Generation, Transmission & Distribution, 2021
Sub‐synchronous resonance (SSR) is a great danger to the stable and safe operation of the synchronous generator and power network. Detecting this condition in a fast and precise method is very important for power engineers.

Reduction of synchronous torques in induction machines using asymmetrical rotor slots

, 2012
Removing the rotor skew in induction machines reduces the negative effects created by inter-bar currents. On the other hand, synchronous torques at low rotor speeds may appear, this can prevent the rotor to reach its rated speed.
