Parameters related to FRT)
These parameters are set automatically upon selecting the grid code.
Parameter Description
FRT upper threshold level Upper grid voltage magnitude for engaging a high-voltage FRT
FRT lower threshold level Lower grid voltage magnitude for engaging a low-voltage FRT
Static reactive power, k Ratio between additional reactive current to be injected during
the FRT and the depth of the sag, k= (ΔI

p.u.
Transition time Duration of period after the sag has cleared, where reactive
current is still injected.
