PSCAD based simulation of the connection of a wind generator to the network

The simulation of the behavior of an induction generator during the connection of a wind turbine by means of a soft starter is presented. The problems concerning the connection of a wind turbine to the network appear more evident when the wind turbine operates alone feeding local loads in weak systems. The reactive power depends significantly on the derivative of the voltage which made the steady state equivalent circuit unsuitable for the study of the voltage drops. A model of the soft-starter and a feasible connection strategy is described and the simulations performed, illustrating that a dynamic model of the induction generator must be taken into account.
