System description 33
With the crowbar and the DC chopper
, the
wind turbine is capable of handling fault
situations like rotor overspeed, short inte
rruptions, voltage dips/sags and swells. With
these energy absorbers, the
converter is capabl
e of meeting eve
n the most strictest grid
fault ride-through requirements in acco
rd
ance with international grid codes.
