Although it is commonly assumed that power swing is symmetrical and will have identical
effects on all three-phase voltages and currents, there is another type of power swing, which …

The power swing characteristic of transmission lines (TLs) can be affected by the large-scale
integration of inverter-based resources (IBRs), resulting in the maloperation of the legacy …

Integration of wind-based renewable energy sources into long Extra High Voltage/Ultra High
Voltage uncompensated/compensated power transmission network poses significant …

Sensitivity, selectivity, speed of operation and reliability of the conventional current
differential protection schemes are affected and limited by the distributed shunt capacitance …

The distance protection in transmission networks is vulnerable to malfunction during a
power swing. Distance relays have a power swing blocking (PSB) function that prevents the …

The 110 kV single outgoing line powered by wind generation usually adopts tripolar tripping
and three-phase auto-recloser. The electrical quantities of the single line attenuate quickly …

Solar storms cause disturbances in the Earth's magnetic field, which results in quasi-DC
geomagnetically induced currents (GICs) flow in the grounded sections of the system. The …

Mal-operation of distance protection relays during power swing (PS) condition can endanger
the power system stability. Therefore, it is crucial to distinguish between short-circuit faults …

With respect to sensitivity, selectivity and speed of operation, the current differential scheme
is a better way to protect transmission lines than overcurrent and distance-based schemes …

Increasing power demand, penetration of renewables, and limitations of necessary grid
expansion are proffering new challenges to existing power system protection and control …
