Efectos de los contactos de alta resistencia en las máquinas síncronas de reluctancia

Faults caused by voltage unbalances as a consequence of high-resistance connection (HRC) are one of the most common problems in electrical systems. HRC increases torque oscillations and vibrations, and generally affect the normal operation of machines. This article presents an analysis of the behavior of a synchronous reluctance motor drive with HRC. Simulation is performed under balanced and unbalanced conditions to study the consequences of voltage unbalance. Finally, experimental results are shown to make a direct comparison with the simulation ones.
