The use of doubly fed induction generator in wind
power plants has result in new necessities to maintain a reliable
operation of the network. The tendency of the grid codes is to
require the ability from the wind power plant to keep connected
during and after grid disturbance, similarly to the synchronous
generators requirements. This paper analyse the behaviour of a
wind power plant equipped with doubly fed induction
generators connected to a transmission system during grid fault
and compare its performance with a conventional synchronous
generator based power plant. The results have shown that the
conventional synchronous generator has much more effective
injection of reactive power during grid fault and, by
consequence, the terminal voltage is kept in higher levels.
