Calculation of the source impedances of the left and right side of the supplying line:
Z
= (1.1 • 110 kV) / (√3 • 20 kA) • e

Calculation of the total impedances between the generators:
Z
= Z

Calculation of the distance to the power-swing center:
Z
= 0.5 • Z

Z
= 0.5 • Z

The power-swing trigger starts operating at a minimum current of 10 % Irated. Power-swing detection
drops out once the current is below the minimum current. Power-swing frequencies between 0.1 Hz and
8 Hz are detected.
For the setting value X reach, use a safety margin of at least 20 %, yielding this result:
X reach = 1.2 • 8.5 Ω = 10.2 Ω.
Use the same setting value for R (ph-g).
Use double the value of X reach for R (ph-ph).
