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

) / (ΔU/U

) ≥ 2.0

p.u.

Transition time Duration of period after the sag has cleared, where reactive

current is still injected.
