Electric Power Systems Research, 2012 This paper develops and analyzes a methodology for detecting stator winding inter-turn faults in surface-mounted permanent magnet synchronous motors. The proposed methodology is based on monitoring the zero-sequence voltage component having into account the effects of the inverter that usually feeds the machine.

Owing to the operational characteristic of a Vienna rectifier, it is found that the traditional modulation method would result in the current distortion. This paper, therefore, proposes a novel zero-sequence component injection modulation method for improving the input quality of the Vienna rectifier with balanced or unbalanced dc-link voltages.

Torque Improvement of Dual Three-Phase Permanent Magnet Machine Using Zero Sequence Components
IEEE Transactions on Magnetics, 2017This paper investigates the interaction of the zero sequence component into both permanent magnet (PM) shape and phase current to improve the output torque in dual three-phase surface-mounted PM (SPM) machines. The optimal zero sequence components are analytically derived and validated by finite element (FE) analyses.

High Impedance Fault Area Location in Distribution Systems Based on Current Zero Sequence Component
IEEE Latin America Transactions, 2016This paper presents a new methodology for detection and area location of high impedance faults (HIF) on unbalanced distribution systems. The method is called Quasi-Differential Zero Sequence Protection (PQDSZ) and it detects these faults by analyzing the current zero sequence rms value on a distribution feeder.
