Effects of Geomagnetically Induced Currents on current transformer and differential protection

2013 IEEE Power & Energy Society General Meeting, 2013
Geomagnetically Induced Current (GIC) has long been recognized to influence current transformer (CT). Treated as quasi-DC, the effects of GIC haven't been discriminated from DC bias caused by High Voltage Direct Current transmission (HVDC). However, the nature of GIC as current with time-varying magnitude and random waveform makes it generate complex ...

Adaptive Quasi-Power Differential Protection Scheme for Active Distribution Networks

IEEE Transactions on Smart Grid
With the massive integration of distributed generations (DGs), distribution networks gradually become more active and flexible. Conventional overcurrent protection is difficult to adapt to such active distribution networks (ADNs).

High-Sensitivity Differential Protection for Offshore Wind Farms Collection Line With MMC-HVDC Transmission

IEEE Transactions on Power Delivery
When single-phase-to-ground (SPG) or phase-to-phase (PP) faults occur on collection lines of an offshore wind farm with modular multilevel converter-based high voltage direct current (MMC-HVDC) transmission, the fault current level may be low or even ...
