Zero-sequence components in unit-connected generator with ungrounded neutral during ground-faults

PowerCon 2000. 2000 International Conference on Power System Technology. Proceedings (Cat. No.00EX409), 2002
An analysis of voltage zero-sequence components in a generator during normal operation (pre-fault conditions) and during ground-faults in stator winding of generator with ungrounded neutral is presented. The changes in voltage zero-sequence components of fundamental frequency and 3rd harmonic during generator pre-fault conditions, ground-faults in ...

A DVR Control for Compensating Unbalanced Voltage Dips of a DFIG System using Zero Sequence Components

Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2013
The dynamic voltage restorer (DVR) is an effective protection device for wind turbine generators based on doubly-fed induction generator (DFIG) that is operated under unbalanced voltage dip conditions. The compensating voltages of the DVR depend on the voltage dips and on the influence of the zero sequence component. The zero sequence component results

Influence on zero-sequence components of autotransformer neutral grounding via small reactance in one 500kV substation

2014 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2014
Transformers neutral grounding accessing small reactance is an effective measure to restrain short circuit current in 500kV power grid. But accessing small reactance will bring changes to the zero-sequence parameters of system. The relay protection, especially the main transformer protection and transmission line protection nearby will be affected and ...
