Modern wind power plants are required and
designed to ride through faults in the network, subjected to the
fault clearance and following grid code demands. Beside voltage
support during faults, the wind turbine fault current
contribution is important to establish the correct settings for the
relay of the protections. The following wind turbine generator during faults have been
studied: (i) induction generator, (ii) induction generator with
variable rotor resistance (iii) converter-fed rotor (often referred
to as DFIG) and (iv) full scale converter.
To make a clear comparison and performance analysis during
faults, and the consequent effects on substation protections, the
aforementioned configurations have been simulated using
PSCAD/EMTDC, with the same power plant configuration,
electrical grid and generator data.
